flutter_screen_recorder_kl #

Open source Flutter plugin for Android screen recording with fast stop (live mux), internal audio + mic mixing (Android 10+), and mic fallback.

Features #

• Live-mux recording to MP4 (no heavy post-stop merge by default).
• Android 10+ internal playback capture + microphone mix.
• Automatic fallback to mic-only if internal capture is blocked/unavailable.
• Android 14+ foreground service support for media projection.

Platform Support #

• Android: supported
• iOS/web/desktop: not implemented in this package

Installation #

dependencies:
  flutter_screen_recorder_kl: ^0.1.0

Android Setup #

Add these permissions to your app AndroidManifest.xml:

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MEDIA_PROJECTION" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MICROPHONE" />

The plugin ships a foreground service declaration via plugin manifest merge.

Usage #

import 'package:flutter_screen_recorder_kl/flutter_screen_recorder_kl.dart';

final recorder = FlutterScreenRecorderKl.instance;

await recorder.startRecording();
final path = await recorder.stopRecording();

Notes #

• Internal playback capture depends on Android policy and target app behavior.
• Some apps/games can block internal capture. The plugin then falls back to mic-only mode.
• This package does not compress by default. You can run your own compression pipeline after stop if needed.
