microphone_flutter library

Flutter integration for the microphone_dart package.

This package contributes the native microphone library to your Flutter app (built automatically via cargokit) and re-exports the full microphone_dart API. In most cases you only need the re-exported Microphone entry point:

import 'package:microphone_flutter/microphone_flutter.dart';

await MicrophoneFlutter.ensureInitialized();
if (await Microphone.requestPermission()) {
  final recording = await Microphone.record();
  // ... later ...
  final wav = await recording.stop();
}

Platform permissions

The microphone is a protected resource; your app must declare it:

macOS / iOS: add NSMicrophoneUsageDescription to the app's Info.plist (a short reason shown in the system prompt). On macOS also enable the "Audio Input" capability / com.apple.security.device.audio-input entitlement for sandboxed apps.
Android: add <uses-permission android:name="android.permission.RECORD_AUDIO"/> to AndroidManifest.xml.

The OS shows its permission prompt the first time capture starts. The web backend prompts via getUserMedia.
