Flutter Screen Mirroring

Flutter screen mirroring refers to the capability of displaying the screen of a Flutter application on another device. This allows developers to showcase their apps on larger screens or test their apps on different devices without needing physical connection or separate installations.

There are multiple ways to achieve screen mirroring in Flutter:

1. Mirroring through Screen Recording and Streaming

One approach is to record the screen of the Flutter app and then stream it to another device over a network connection. This can be done using various screen recording and streaming tools in Flutter, such as the flutter_screen_recording package or third-party solutions like Firebase or Agora.

Here is an example of using the flutter_screen_recording package to record and stream the screen: 


import 'package:flutter/material.dart';
import 'package:flutter_screen_recording/flutter_screen_recording.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Screen Mirroring Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () async {
              if (await FlutterScreenRecording.checkIfRecording) {
                FlutterScreenRecording.stopRecordScreen();
              } else {
                FlutterScreenRecording.startRecordScreen();
              }
            },
            child: Text('Toggle Screen Recording'),
          ),
        ),
      ),
    );
  }
}

2. Mirroring through Streaming Platforms

Another method is to leverage streaming platforms like Twitch or YouTube to broadcast the screen of the Flutter app. This involves setting up a streaming channel and using Flutter libraries like flutter_twitch or flutter_youtube to stream the app’s screen content to the corresponding platform.

Here is an example of using the flutter_twitch package to stream the app’s screen content to Twitch: 


import 'package:flutter/material.dart';
import 'package:flutter_twitch/flutter_twitch.dart';

class MyApp extends StatelessWidget {
  final String channelName = 'your_channel_name';
  
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Screen Mirroring Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () async {
              await FlutterTwitch.streaming(channelName, 'your_twitch_token');
            },
            child: Text('Start Screen Mirroring'),
          ),
        ),
      ),
    );
  }
}

3. Mirroring through Remote Debugging

Remote debugging allows you to mirror the app’s screen on a different device by connecting it through a development tool like Chrome DevTools or Visual Studio Code. This method requires setting up remote debugging and connecting the Flutter app to the debugging tool.

Connect to Chrome DevTools:

– Open Chrome browser and type “chrome://inspect” in the address bar.

– Enable the “Discover USB devices” option if your device is connected via USB.

– Click on the “Inspect” link next to the Flutter app you want to mirror.

Connect to Visual Studio Code:

– Install and configure the Dart and Flutter extensions in Visual Studio Code.

– Connect the device to your computer via USB.

– Open the command palette (Ctrl+Shift+P) and select “Flutter: Attach Device”.

These are just a few examples of how you can achieve screen mirroring in Flutter. The approach you choose depends on your specific requirements and the preferred method of mirroring for your app.
