작업을 위해 Flutter 또는 React Native를 선택하는 것이 더 나은 주제 분석을 시작하겠습니다. 모든 것이 어디서 시작되었는지 인식해야 합니다. DataReportal의 Digital 2022 Global Statshot 통계 및 보고서에 따르면 지구상의 거의 70%의 사람들이 매일 휴대전화를 사용합니다.

즉, 현대인의 라이프스타일이 모바일 애플리케이션 산업에 엄청난 수혜를 안겨준 셈이다. 그러므로 따라서 후자를 개발하는 경우는 여전히 매우 적절하다. 결국 오늘날의 기술 리더인 Google과 Facebook이 만든 Flutter & React Native가 등장합니다.

우리는 다음 질문을 고려하여 본 연구에서 어떤 것을 선택하는 것이 더 나은지 논의할 것입니다.

본 연구에서는 다음 질문을 고려하여 완벽한 선택에 대해 논의할 것입니다.

• 반응이란 무엇입니까?

• 2023년에 무엇을 선택할 것인가: Flutter 또는 React Native?
• 마지막 생각들.

Flutter 및 React 앱 개발에 대한 풍부한 정보가 매일 인터넷에 넘쳐나는 시대에 우리는 더 깊이 탐구한다는 점을 강조하는 것이 중요합니다. 이 글에서는 Flutter와 React Native의 중요한 차이점을 살펴보고 차이점을 살펴보겠습니다.

그럼, 조사를 시작하겠습니다!

리액트 네이티브와 Flutter

Flutter와 React Native의 비교는 새로운 것이 아니며 광범위하게 논의된 주제입니다. 그러나 어떤 도구가 더 우수한지에 대한 질문에 대한 명확한 답은 아직 파악하기 어렵습니다. 두 프레임워크 모두 열광적인 헌신적인 커뮤니티와 함께 ​​각각의 장점과 단점을 가지고 있습니다. 이 기사의 목표는 Flutter와 React Native에 대한 포괄적인 이해를 제공하여 이러한 하이브리드 기술의 복잡성을 보다 효과적으로 탐색할 수 있도록 하는 것입니다. 이러한 지식을 바탕으로 정보에 입각한 선택을 하고 선호도에 맞는 도구를 선택하는 데 더 많은 준비를 갖추게 될 수 있습니다.

Flutter와 React Native의 비교는 그렇지 않으며 이미 충분히 논의된 주제입니다. 더욱이 어떤 도구가 최고의 도구인지에 대한 결정적인 답변은 여전히 ​​어렵습니다. 두 프레임워크 모두 고유한 강점과 약점을 갖고 있으며, 각 프레임워크에는 열렬한 지지자 커뮤니티가 수반됩니다. 이 기사의 목표는 Flutter 및 React Native에 대한 포괄적인 이해를 제공하여 이러한 하이브리드 기술의 복잡성을 더욱 능숙하게 탐색할 수 있도록 지원하는 것입니다. 이러한 지식을 통해 귀하는 현명한 결정을 내리고 귀하의 선호도에 가장 적합한 도구를 선택할 수 있는 준비를 갖추게 될 것입니다.

플러터는 무슨 뜻인가요?

Flutter에 대해 이야기하기 시작할 때 이것이 모바일 앱이나 휴대용 소비자 인터페이스 도구 키트를 만들기 위한 크로스 플랫폼 플랫폼이라는 점을 정확히 말할 필요가 있습니다. 개발자에게 도구 및 위젯으로 구성된 완전한 소프트웨어 개발 키트(SDK)를 제공합니다.

Flutter로 데스크톱 앱을 만들 때 Flutter 소스 코드를 기본 Windows, Linux 또는 macOS 데스크톱 앱으로 수집할 수 있습니다. 예를 들어 Flutter의 웹 지원은 인터넷 및 모바일 장치에서 동일한 프로세스를 제공합니다. 이는 이제 동일한 코드베이스에서 iOS, Android 및 웹 브라우저용 애플리케이션을 만들 수 있음을 의미합니다.

Google 팀에서 개발하고 Dart를 기반으로 구축된 Flutter는 무료이면서도 비교적 새로운 기능으로, 접근성이 뛰어나고 이해하기 쉽습니다. 고성능 렌더링 엔진으로 구동되는 사용자 정의 위젯 컬렉션을 제공합니다. 특히 Google과 Flutter 커뮤니티는 지속적인 개발에 적극적으로 기여하고 있습니다. 결과적으로 Flutter는 자신있게 신흥 기술로 분류될 수 있습니다.

초기 반복에서 Flutter는 Android 및 iOS와 호환되는 모바일 애플리케이션을 만들기 위한 툴킷을 제공했습니다. 후속 버전을 통해 발전하면서 Flutter는 다양한 플랫폼에 대한 지원을 포괄하도록 범위를 확장했습니다. 이 확장에는 Windows, macOS, Linux, 웹 애플리케이션 및 Flutter 사용을 위해 맞춤 제작된 특수 플랫폼이 포함되었습니다. 특히 2023년 1월 Flutter 3.7의 출시는 중요한 이정표였습니다. 이 업데이트에는 iOS에 최적화된 렌더링 엔진, Material 3 및 iOS 스타일 위젯에 대한 향상된 지원, 향상된 현지화 솔루션, 더욱 효율적인 배경 데이터 처리, 개발 도구 개선 등 다양한 새로운 기능이 도입되었습니다.

반응은 무엇을 의미합니까?

반면 React Native는 JavaScript를 활용하고 Facebook에서 제작한 모바일 앱용 오픈 소스 프레임워크입니다.

2023년에 React Native를 배워야 하는 가장 강력한 이유 중 하나는 플랫폼 독립성입니다. 과거에는 개발자들이 Android 애플리케이션 개발에는 Java를, iOS 애플리케이션 개발에는 Swift를 주로 활용해야 했습니다. 게다가 Windows와 같은 다른 플랫폼도 있어서 프로세스가 더 복잡해졌습니다. React Native는 여러 플랫폼에서 원활하게 실행되는 앱을 만들기 위한 완벽한 옵션으로 등장합니다. React Native를 사용하면 앱을 한 번만 빌드하면 모든 주요 플랫폼에서 쉽게 실행됩니다. 또한 React Native는 React에 익숙한 사람들에게 친숙한 JSX를 활용하며 종종 HTML과 JavaScript의 혼합으로 정의됩니다. 이러한 친숙함 덕분에 일부 어려운 개념에도 불구하고 React Native를 비교적 쉽게 배울 수 있습니다. 유사한 목표를 위해 Java를 활용하는 것과 비교할 때 React Native를 사용한 구성 앱은 훨씬 더 쉽고 효율적입니다.

React Native는 Flutter보다 오래되었으며 더 큰 커뮤니티를 자랑한다는 점을 강조해야 합니다. 계속 읽어보자!

React와 Native Flutter의 차이점

아래에서는 두 프레임워크의 장점과 단점에 대해 설명하겠습니다.

기본 성능 비교

Flutter는 AOT(Ahead-of-Time) 컴파일러를 활용하여 프로젝트가 빌드된 후 iOS 및 Android에 최적화된 코드를 생성하여 애플리케이션 바이너리에 전체 코드베이스를 포함할 필요 없이 네이티브 수준의 성능을 보장합니다. 이는 React Native와 공통된 기능입니다. . 특히, 네이티브 모듈과 상호작용하기 위해 브리지를 요구하는 React Native와 달리 Flutter는 네이티브 모듈과 직접 통신합니다.

React Native는 JIT 컴파일러 덕분에 V8보다 뛰어난 향상된 JavaScript 가상 머신을 자랑합니다. 사전 컴파일된 프레임워크로서 모든 코드베이스를 배포하고 기본 실행 파일로 컴파일할 수 있습니다. 일반적으로 React Native는 iOS 빌드 설정을 조정할 필요 없이 iOS 애플리케이션 수준에서 수행하여 기본 앱과 동일한 속도를 달성합니다.

React Native는 JIT 컴파일러 덕분에 성능 면에서 V8을 능가하는 뛰어난 JavaScript 가상 머신을 갖추고 있습니다. 사전 컴파일된 프레임워크로서 모든 코드베이스를 기본 실행 파일로 배포하고 컴파일하는 것을 용이하게 합니다. 일반적으로 React Native는 iOS 빌드 설정을 수정할 필요 없이 iOS 애플리케이션 수준에서 수행하여 기본 앱과 동일한 속도를 달성합니다.

결론 : Flutter와 React Native 모두 네이티브 수준의 높은 성능을 자랑하지만 Flutter는 네이티브 모듈과 직접 통신합니다.

프로그래밍 언어

React Native는 동적 웹 개발을 가능하게 하는 최초의 언어인 고전적인 JavaScript 프로그래밍 언어를 활용합니다.

Flutter는 2011년에 발표된 이후 훨씬 새로운 언어인 Dart를 활용합니다.

JavaScript는 Dart에 비해 더 광범위하고 광범위하게 사용됩니다. 결과적으로 개발자는 React Native 애플리케이션 개발에 뛰어드는 것이 더 익숙하고 편안하다고 생각하는 경우가 많습니다.

결론: Flutter와 React Native 프로그래밍 언어 모두 무결성이 있지만 React Native가 승리합니다.

신뢰할 수 있음

안정적인 플랫폼을 사용하여 모바일 애플리케이션을 신속하게 개발하는 것이 우선이라면 Flutter가 더 나은 옵션이 될 수 있습니다. 반대로, 강력한 지원 생태계와 강력한 UI 기능을 자랑하는 잘 확립된 플랫폼을 찾고 있다면 React Native가 더 적절한 선택일 수 있습니다.

결론 : React Native와 Flutter는 모두 안정적이지만 React Native는 강력한 지원 생태계를 갖추고 있습니다.

소비자 인터페이스 구축

React Native 프레임워크는 Flutter의 규모를 능가하는 광범위하고 활발한 커뮤니티로 돋보입니다. 풍부한 UI 디자인, 라이브러리, 철저한 문서 및 수많은 보충 리소스를 제공합니다. 또한 React Native는 Flutter와 비교할 때 훨씬 더 풍부한 타사 라이브러리를 자랑합니다.

결론: React Native는 소비자 인터페이스를 구축하는 데 가장 적합한 옵션입니다.

선적 서류 비치

Flutter에는 Android와 iOS 모두에 대한 명확한 플랫폼 설정 및 IDE 정보가 있습니다. 명령줄 인터페이스(CLI)도 개발자의 설정을 지원하는 도구인 Flutter Doctor와 함께 제공됩니다.

오픈 소스 특성 덕분에 Flutter는 뛰어난 사용자 정의 및 유연성을 제공하므로 개발자는 독특한 소비자 경험을 쉽게 준비할 수 있습니다.

React Native는 새로운 업데이트가 나올 때마다 계속해서 발전하고 있습니다. 계속해서 교육을 받으려면 React Native의 공식 문서 와 웹 리소스를 주의 깊게 살펴보세요 .

결론: Flutter는 포괄적인 문서를 자랑하지만 React Native는 끊임없이 진화하고 있습니다.

설치 용이성

React Native 설치는 간단하지만 패키지를 생성하므로 일부 개발자에게는 사소한 불편함으로 보일 수 있습니다. 그러나 이 요소는 사용자마다 중요도가 다릅니다. React Native는 주로 UI 렌더링 및 장치 액세스 API를 제공하며 해당 기능을 보완하기 위해 타사 라이브러리에 의존한다는 점은 주목할 가치가 있습니다.

React Native 설치는 간단한 프로세스이지만 패키지 생성이 포함되어 있어 특정 개발자에게는 사소한 불편으로 간주될 수 있습니다. 이 요소의 중요성은 사용자마다 다르다는 점을 강조하는 것이 중요합니다. 또한 React Native는 기능 향상을 위해 타사 라이브러리에 따라 주로 UI 렌더링 및 장치 액세스 API를 제안한다는 점에 주목할 가치가 있습니다.

Flutter는 작은 ZIP 파일에서 얻을 수 있지만 명령줄에서 PATH 변수로 추가해야 합니다. 이것은 일을 불필요하게 어렵게 만듭니다.

결론: React Native는 Flutter보다 설정하기가 훨씬 쉽습니다.

지역 사회

React Native는 Flutter보다 앞서며 더 큰 커뮤니티를 자랑합니다. 또한 Meta 팀은 API를 개선하고 근본적인 문제를 해결하는 데 많은 시간을 보냈습니다.

React Native는 버전 0.70부터 기본 엔진이었던 새로운 JavaScript 엔진 Hermes를 채택하여 성능 최적화 및 메모리 사용량 감소 측면에서 상당한 진전을 이루었습니다. 이에 대한 더 자세한 내용은 React Native 블로그 게시물을 참조하세요.

또한 Meta는 다음과 같은 몇 가지 중요한 개선 작업을 적극적으로 진행하고 있습니다.

• 린 코어(Lean Core): 여기에는 선택적 구성 요소나 기능을 별도의 저장소에 재배치하여 개발자가 필요에 따라 이를 애플리케이션에 추가할 수 있도록 하여 애플리케이션의 크기를 줄이는 것이 포함됩니다.
• React Native Fabric: 성능 향상을 위해 재구성된 UI 레이어입니다.
• TurboModules: 이는 기본 모듈 처리를 개선하는 것을 목표로 합니다.

결론: React Native는 이제 Flutter에 비해 더 크고 강력한 커뮤니티 지원을 자랑합니다.

디버깅

React Native에서는 디버깅이 어려울 수 있습니다. 특히 앱의 기본 부분 어딘가에 특정 예외나 실수가 나타날 경우 더욱 그렇습니다.

반면 Flutter는 Android Studio 및 Visual Studio와 원활하게 통합되는 도구를 제공하여 디버깅 프로세스를 단순화하고 개발 워크플로를 간소화합니다.

결론: Flutter가 이 비교에서 승리했습니다.

인기

2023년 현재 Flutter와 React Native라는 두 가지 주요 하이브리드 앱 개발 프레임워크가 계속해서 업계를 지배하고 있습니다. 놀랍게도 두 프레임워크의 인기는 계속 높아지고 있습니다. 2023년에는 42%의 개발자가 앱 개발을 위해 React Native를 선호했으며, Flutter가 39%로 그 뒤를 바짝 쫓고 있습니다.

올해인 2023년에도 Flutter와 React Native라는 두 가지 주요 하이브리드 앱 개발 프레임워크가 여전히 영향력을 행사하고 있습니다. 흥미롭게도 두 프레임워크의 매력이 계속 높아지고 있습니다. 올해 React Native는 개발자 중 42%가 애플리케이션 개발을 선호했으며, Flutter가 39%로 그 뒤를 바짝 쫓고 있습니다.

결론: React Native는 인기로 승리합니다.

위의 내용을 표로 요약해 보겠습니다.

계속하자!

2023년에 무엇을 선택할 것인가: React Native 또는 Flutter

Flutter를 선택할지, React Native를 선택할지 고민할 때 명확하거나 간단한 대답이 없다는 점에 유의하는 것이 중요합니다. 두 옵션 모두 실행 가능한 선택입니다.

우리가 알 수 있는 한, React Native와 Flutter는 공통점이 많지만 많지는 않습니다. 첫 번째이자 가장 중요한 사실은 둘 다 누구나 활용할 수 있는 오픈 소스 프레임워크라는 것입니다.

Flutter 프레임워크와 그것이 2023년 프로젝트에 적합한 선택인지에 대해 여전히 질문이 있는 경우 이 주제에 대한 연구 중 하나를 읽어 보시기 바랍니다 .

2023년에 어떤 기술이 승자가 될지 정의하는 것은 간단한 과제가 아닙니다. React Native와 Flutter는 모두 다양한 장단점을 보여줍니다. Flutter는 크로스 플랫폼 모바일 앱을 만들기 위한 신속하고 신뢰할 수 있는 프레임워크로 두각을 나타내며, 다양한 오픈 소스 라이브러리 및 강력한 플러그인 생태계에 대한 액세스를 제안합니다. 반면에 React Native는 개발자가 JavaScript를 활용하여 복잡한 소비자 인터페이스를 만들 수 있도록 지원하고 광범위하고 헌신적인 개발 커뮤니티의 이점을 누릴 수 있습니다.

궁극적으로 이 두 프레임워크 사이의 선택은 아마도 개인의 필요와 선호도에 달려 있을 것입니다. 신속한 모바일 애플리케이션 개발을 촉진하는 빠르고 안정적인 플랫폼을 우선시한다면 Flutter가 더 나은 선택일 수 있습니다. 게다가, 포괄적인 지원과 강력한 UI 기능을 갖춘 잘 확립된 플랫폼을 찾고 있다면 React Native가 귀하의 요구에 더 나은 옵션이 될 수 있습니다.

How to Implement Deep Linking in Flutter?

Flutter에서 딥링킹을 구현하는 방법은 무엇입니까?

https://medium.com/@dudhatkirtan/how-to-implement-deep-linking-in-flutter-f882b6d834da

Overview

Deeplink in Flutter means the ability to open a specific page or perform a specific action within your app by clicking on a link from another app or a web page. It allows users to navigate to specific pages or sections of your app like cart, orders, or any product information, etc. Deeplink in Flutter is a very good feature for all developers and users. Flutter supports deep linking on iOS, Android, and web browsers. Implementing deep linking in Flutter apps enhances the user experience and makes it easier for users to navigate directly to specific sections.

Introduction

Deep linking is a crucial feature in mobile app development that enables smooth navigation to specific sections of different apps. This is very useful for users to access relevant content or perform specific tasks without manually navigating through the app’s screens. This deep linking feature eliminates the need for users to search for or manually locate the desired information within the app. Deep linking is a useful functionality for apps like e-commerce apps, content-driven apps, and social media platforms. By using deep links in Flutter, we can connect with other apps and services making it a good digital ecosystem.

Understanding Deep Links in Flutter

DeepLinks in Flutter means you have URLs or URIs to navigate or perform specific actions within a Flutter app. It directly helps users to access specific screens or content like webpages, screens, and notifications.

There are some concepts and terms that should be known to developers for using deep links in the Flutter applications.

• URL Scheme -
• A URL scheme is a unique identifier that identifies your app and allows it to handle specific deep links. It is generally a link to view or see a particular product in an e-commerce app.

Universal Links (iOS) and App Links (Android):

• These are platform-specific mechanisms that help deep linking to work smoothly between web content and apps. These help in directly opening the content of the app, if the app is installed on the device, or fall back to the web page if the app is not present.

Deep Link Handling :

• We need to handle the logic for deep lonks in Flutter like capturing the link URL and getting important data such as parameters or query strings. This captured information helps in navigating to a particular screen or performing the actions.

Implement Deep Linking on Android

To use deep links in your Flutter applications, we must have links for redirection that can be instantiated by adding intent filters for the incoming links.

In Android, we have two types of Uni Links, which are approximately the same as the meaning.

Open the DynamicLink section in firebase

• On a domain that you may customize by adding your own name, company name, trademark, etc., dynamic links are generated. More relevant links that have been customized appear. After displaying this window, click Finish.

• Now, on the newly opened page, select the “New Dynamic link” button.

• Click on the new dynamic link button.

App Links -

App Links are the same as deep links, but it does require a specified host, i.e. a hosted file and along with this, the app links only tend to work with the HTTPS scheme.

You need to add the following code to your AndroidManifest file for adding deep links in Flutter. There you have to define an intent-filter and you can change the host with your need.

<!-- This is for App Links -->

<meta-data
            android:name="flutter_deeplinking_enabled"
            android:value="true" />

      <intent-filter android:autoVerify="true">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <!-- Accepts URIs that begin with https://YOUR_HOST -->
        <data
          android:scheme="http"
          android:host="deeplink.example.com" />
            <data android:scheme="https" />
      </intent-filter>

Deep Links -

Deep links are the links in Android, which don’t require a specified host or any other custom scheme.

As discussed above, we have to paste for Deep links and we can change the host and scheme accordingly.

<!--  This is for Deep Links --> 
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" /> 
<category android:name="android.intent.category.BROWSABLE" /> 
<!-- Accepts URIs that begin with YOUR_SCHEME://YOUR_HOST --> 
<data android:scheme="blog" android:host="deeplink.example" /> 
</intent-filter>

We can use any of the intent filters in the AndroidManifest.xml file.

The intent filter is a statement in the manifest file that specifies what intent or component will be received on the app side, according to native app implementation. When an action occurs, it can specify additional actions that should be taken on this intent filter.

Data is what the URI format, which primarily resolves to the activity, represents. Also, a data tag must have the android attribute.

A category is mainly the type of intent-filter category. We have defined BROWSABLE in the category, which means that the intent filter can be accessed from the browser, and if not added, it will not be browsed.

Implement Deep Linking on iOS

In iOS also, we have two types of links-

Universal Links :

Universal links are those links that require a specified host or a custom scheme in their app. It works only with the HTTPS scheme. Below is the defined example of a universal link.

For setting up Universal Links we need to follow some steps-

• Enable Associated Domains in your app’s entitlements.
• Set up a unique URL identifier for your app.
• Set up a JSON file on your website that contains information about your app’s URL identifier.

Enable Associated Domains

Creating the entitlements file in Xcode:

• Open up Xcode by double-clicking on your ios/Runner.xcworkspace file.
• Go to the Project navigator (Cmd+1) and select the Runner root item at the very top.
• Select the Runner target and then the Signing & Capabilities tab.
• Click the + Capability (plus) button to add a new capability.
• Type “associated domains” and select the item.
• Double-click the first item in the Domains list and change it from webcredentials.com to: applinks: + your host (ex: my-blogs.com). A file called Runner.entitlements will be created and added to the project.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<!-- ... other keys -->
<key>com.apple.developer.associated-domains</key>
<array>
  <string>applinks:[YOUR_HOST_HERE]</string>
</array>
<!-- ... other keys -->
</dict>
</plist>

Custom URL:

In Custom URL, we don’t need a host or a custom scheme for our iOS app. An example of a custom URL is defined below. We need to add the host and scheme in the ios/Runner/Info.plist file.

<key>FlutterDeepLinkingEnabled</key>
<true/>
<key>CFBundleURLTypes</key>
<array>
  <dict>
  <key>CFBundleTypeRole</key>
  <string>Editor</string>
  <key>CFBundleURLName</key>
  <string>flutterbooksample.com</string>
  <key>CFBundleURLSchemes</key>
  <array>
  <string>customscheme</string>
  </array>
  </dict>
</array>

Handling Deep Linking in the App

There are two ways your app will receive a link — from a cold start and brought from the background.

ATTENTION -

getInitialLink/getInitialUri should be handled ONLY ONCE in your app’s lifetime, since it is not meant to change throughout your app’s life

Once we are done with the Universal Links set up for our app, we will need to handle the links within our Flutter app. To do this, we need to use the uni_links package. Add this dependency in pubspec.yaml file and pub get it.

uni_links: ^0.5.1

Now, we just need to register a callback to handle incoming deep links.

import 'package:uni_links/uni_links.dart';

void main() {
   // Initialize the deep link handler
   initUniLinks();
   runApp(MyApp());
}

void initUniLinks() async {
   // Ensure that the app is ready to handle deep links
   await getInitialUri();

   // Set up a stream subscription to handle deep links when the app is running
   uriSubscription = uriLinkStream.listen((Uri uri) {
      // Handle the deep link here
      handleDeepLink(uri);
   });
}

void handleDeepLink(Uri uri) {
   // Process the deep link URI and navigate accordingly
   // You can extract parameters or perform specific actions based on the deep link data
}

Advanced Usage

Some additional features enhance the capabilities of deep linking in our Flutter app. These features help in creating more personalized and smooth user experiences, tracking user engagement, optimizing marketing efforts, and improving overall app performance.

Deep Link Analytics -

By implementing Deep Link Analytics, we can track and analyze user engagement with deep links. We can get the data on the number of clicks, conversions, and user behavior after accessing the app through a deep link. With this information, we can get to know about our deep links and can do some optimization if needed.

Deferred Deep Linking -

This helps in handling the scenarios, where the app is not installed on the user’s device on clicking the deep link. In these cases, the user is redirected to the app store to download the app and after installation, the app can open and handle the deep link that triggered the installation.

Dynamic Deep Links -

These help in generating deep links programmatically with dynamic parameters. It means we can generate deep links that include user-specific data, product IDs, or other variables.

Deep Link Attribution -

By using this you can track the source of each deep link and can know which channels are getting more engagement and conversions.

Deferred App Deep Linking -

Some platforms handle deep links when the app is already installed but not in the foreground. But this feature works even if the app is in the background or not currently running.

Example App

Let us understand this through a code. In the AndroidManifest.xml file, I have declared my link like — blog://deeplink.example

We will declare the function main.dart file like this.

import 'package:blog/home.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:uni_links/uni_links.dart';
import 'package:flutter/services.dart' show PlatformException;

void main() {
  initUniLinks();
  runApp(MyApp());

 initUniLinks()async{
  try{
    Uri? initialLink = await getInitialUri();
    print(initialLink);
  } on PlatformException {
    print('platfrom exception unilink');
  }
}
}


class MyApp extends StatelessWidget {

  @override
  Widget build(BuildContext context){
    return MaterialApp(
      home: HomeScreen(),
    );
  }
}

There is some page that says it as HomeScreen.

import 'package:flutter/material.dart';

class HomeScreen extends StatefulWidget {
  const HomeScreen({Key? key}) : super(key: key);

  @override
  State<HomeScreen> createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {

    return const Scaffold(
      body: Center(
        child: Text("Home Screen"),
      ),
    );
  }
}

We will open this app through the deeplink shown below. We will paste the same link(blog://deeplink.example) in the browser and it will show us the APP NAME of that app and will navigate us to the app by clicking on continue

Conclusion

1. Deep links help in seamless navigation to specific screens from external sources like the web, notifications, etc.
2. By using deep links, users are more engaged and satisfied. This also helps users to users to access relevant and personalized content.
3. Deep links provide cross-platform compatibility like for both iOS and Android.
4. Deep links can be customized with parameters or query strings, allowing for dynamic and personalized experiences based on user-specific data.
5. We can test and analyze deep links, also we can track user behavior, and optimize our app’s deep linking strategy.
6. By using deep links in Flutter, we can interact with other apps, services, or platforms. Also, we can collaborate and share the data.

Flutter vs React Native

https://medium.com/@vikranthsalian/flutter-vs-react-native-396216ad41d3

Developers often find it difficult to choose between Flutter vs React Native. Both have been created by the current tech giants of the world, Facebook and Google.

But the question of what to use to create these apps has been around for a while.

Flutter

is an open-source UI framework developed by Google in 2017 that aims to design cross-platform apps to run on mobile, Windows, macOS, and Linux as well as on the web. Flutter’s framework is built upon Dart. A lot of big companies like Alibaba, Philips Hue, Hamilton, etc., choose Flutter for development. Moreover, Google frequently provides updates for Flutter, improving its performance with each update.

Advantages of using Flutter

1. Great UI
2. Has a number of widgets
3. Apps are faster
4. Helps build web apps
5. Well-structured documentation and community
6. Helps replicate and create the same UI for different devices

Disadvantages of Flutter

1. Not native
2. Apps are larger
3. Has a limited set of tools

React Native

Facebook developed React Native in 2015. It is an open-source framework that is based on JavaScript. It also provides a similar feature, using the same codebase to create cross-platform apps, thus eliminating the need to compile other technologies for creating mobile apps. Skype, Instagram, Uber Eats, etc., depends upon React Native for development.

Advantages of using React Native

1. Uses JavaScript
2. Can create apps for multiple platforms using a single codebase
3. Understands the importance of code reusability and promotes it
4. Growing and active community
5. Helps in accelerating coding time

Disadvantages of using React Native

1. Not native
2. Does not provide innovative, out-of-the-box components
3. Limited choices
4. Abandoned libraries and packages
5. UI can be hampered easily and needs to undergo vigorous UI testing
6. Larger apps

Differences between Flutter vs React Native

React Native and Flutter are amazing choices for developing a cross-platform application, however, they share several differences which make them unique from each other.

• One major difference is the programming languages both frameworks use. React Native is based on JavaScript and uses JSX. However, Flutter uses Dart programming language.
• The architecture for both frameworks differs. Flutter uses a 2D graphic rendering library, Skia, whereas, React Native uses the Flux architecture, which also requires JavaScript bridging. Here, JavaScript bridging is necessary for React Native to allow JavaScript and Native code to interact with each other. However, there is no programming bridge in Flutter.
• Flutter and React Native documentation guides are very good. However, Flutter shares more organized and structured documentation. React Native documentation is poorly maintained because it depends heavily on third-party libraries.
• Installing Flutter requires you to download the binary from GitHub and also to set up the environment variables on your system. On the other hand, React Native is installed using node package manager (NPM) with one command on your terminal.
• Flutter relies on its developed widgets for customization, whereas React Native incorporates third-party customization components. Therefore, flutter offers more compatibility. Moreover, Flutter development is solely constructed upon Widgets, whereas React Native uses JSX.
• React Native has better support for 3D, whereas, Flutter does not support 3D.

Conclusion :

This blog explains the reasons behind the great popularity of the two emerging frameworks Flutter and React Native, for creating cross-platform applications. Flutter and Native solve the issue of creating separate code for native platforms like Android and iOS. Now, you can create an application for all the platforms using entirely the same code.

Moreover, picking the best framework for yourself depends upon your experience, requirements, and the business needs of your project. If you’re already aware of the JavaScript programming language, then there’s no doubt that React Native is a good choice. However, if you’re targeting a highly stable and fast performance, Flutter has several advantages over React Native.

Happy Coding!!!

What is Flutter Impeller?

https://blog.nonstopio.com/flutter-impellers-d18d47a809d9

Credits: wikiHow

Flutter 3.10 introduces Impeller in iOS apps by default. So these iOS apps will have less jank and better consistent performance. And for Android, Impeller is in the development phase. But we should know what Impeller is.

Impeller is a new renderer within Flutter’s engine. Until now, Flutter has been using Skia. Skia has built-in rendering features which can be used for various devices. But Skia is not always optimized solution for Flutter’s needs.

Before going further, let’s see

The basic Scenario of Impeller is that (check this issue)-

If we had a static set of shaders, we could asynchronously compile them on program startup, so that by the time the application runs an animation we can use this static set and not stutter while we prepare a new one.

Medium term we could also determine what specialized shaders we would want to use in each scene, and compile them in the background so that the next time, if all the specialized shaders we would want to use are ready, we could just use them. That way we get the long-term sustained performance benefits of specialized shaders and the short-term smooth start performance benefits of a static shader set.

Yes, our main goal is to eliminate jank or any stuttering that’s happening inside your app. But first, we should know what is Renderer.

Renderer software helps to translate the code into the pixels that are visible on the screen.

Whenever we build any widget into the Flutter that goes into some steps like Widget Tree -> Element Tree -> Render Object Tree.

But what happened after that? We will go step by step.

1. Display List — Render objects contain the instruction for how to actually layout and how that widget should be painted, in the form of instructions, and those instructions are given to the engine as a simple command, which is called Display List. Now an engine will decide whether the widget should be rendered either using Impeller or Skia.

2. Render Pipelines — Render Pipelines that can be used to render everything given in the Display List.

3. Shader — A Shader is nothing but a small piece of code that gets executed on the graphics device.

4. Rasterization — Shaders take the vertices (say for ex. Flutter Logo) and it will move them on the screen where exactly we want to draw it. This process will iterate through all the given triangles of this Flutter Logo(Ex. Fig.1). For each vertex into say triangle of any image, we figure out the specific pixels that are inside it, and this is called rasterization.

But wait...

Those Shaders and Render Pipeline need compilation to get instructed by the GPU so that GPU can execute it.

AND THIS COMPILATION PROCESS IS VERY EXPENSIVE.

And that’s how Impeller comes into the picture. Let’s discuss this issue in detail.

Shader Compilation Jank Issue —We know that Shaders are the low-level code given to GPU to draw UI on screen.

Skia compiles and generates these shaders (at runtime) when running app for the first time. The generation of shaders requires quite a bit of time(approx. 200ms or more depending on the situation) and this causes the frame, which can’t be rendered within 16ms to jank. This jank is called shader-compilation-jank.

Impeller resolved this issue by pre-compiling a smaller, simpler set of shaders at build time.

First, we will see how exactly Impeller Architecture works,

Now let’s take this Display List and draw it using Impeller.

Impeller Architecture

1. Aiks — The Display List operations are dispatched to Aiks. Aiks is the topmost layer of Impeller and it mainly contains the canvas drawing API.

2. Entity — Aiks takes the higher level commands from the DisplayList and translates them into the simpler self-contained drawing operations called Entities.

3. Contents of Entity — These are the Content Objects of the Entity, and it contains the actual GPU instructions need to draw the Entity.

4. Hardware Abstraction Layer [HAL] — Impeller needs some kind of translation layer by which it can communicate with the GPU, which called as Hardware Abstraction Layer. Render Pipelines contain the Shaders, and each Content of Entity uses the HAL to draw itself by giving instructions to GPU to render these Shaders. This HAL talks to the graphics driver through various standard graphics APIs like Metal on iOS and Vulcan on Android. And then this is how the resulting texture gets displayed on the screen.

Impeller generates and compiles all necessary Shaders (ahead of time) when we build the Flutter Engine. Therefore apps running on Impeller will have a predefined set of Shaders they need, and the shaders can be used without introducing jank into animations. This operation can be done by using Impellerlc Shader Compiler.

Impellerlc Shader Compiler — Impeller has a set of handwritten shaders compiled in advance. Impeller precompiles a smaller, simpler set of shaders at Engine build time so they don’t compile at runtime.

After a preview period since January 2023, Impeller is now on-by-default on iOS in a stable branch. Android up next.

How to Enable Impeller ?

Here, I have taken this example and tried to run it from the IDE (Android Studio).

Pre-Impeller build

Can you see that, the app got stuck at a very early stage of the app run.

Now as per this, to see what direction Android support will take, experiment with Impeller in the 3.7 or later stable release, I enabled Impeller for Android and tried to run the same app from scratch. And got the below observations.

Post-Impeller build

Here, the animation runs smoothly after enabling Impeller.
