hybrid_media 是一个 Flutter 插件，用于处理多媒体文件，包括音频和视频的录制、播放、编辑等操作。它结合了原生平台（Android 和 iOS）的能力，提供了跨平台的多媒体处理功能。

安装插件

首先，你需要在 pubspec.yaml 文件中添加 hybrid_media 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  hybrid_media: ^0.0.1  # 请使用最新版本

然后运行 flutter pub get 来安装插件。

基本用法

1. 初始化插件

在使用 hybrid_media 之前，通常需要初始化插件。你可以在 main.dart 中进行初始化：

import 'package:hybrid_media/hybrid_media.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await HybridMedia.initialize();
  runApp(MyApp());
}

2. 录制音频

hybrid_media 提供了录制音频的功能。你可以使用 HybridMediaAudioRecorder 来录制音频：

import 'package:hybrid_media/hybrid_media.dart';

class AudioRecorderPage extends StatefulWidget {
  [@override](/user/override)
  _AudioRecorderPageState createState() => _AudioRecorderPageState();
}

class _AudioRecorderPageState extends State<AudioRecorderPage> {
  HybridMediaAudioRecorder _audioRecorder = HybridMediaAudioRecorder();
  bool _isRecording = false;

  Future<void> _startRecording() async {
    await _audioRecorder.startRecording();
    setState(() {
      _isRecording = true;
    });
  }

  Future<void> _stopRecording() async {
    String filePath = await _audioRecorder.stopRecording();
    setState(() {
      _isRecording = false;
    });
    print("Audio saved to: $filePath");
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Audio Recorder'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            _isRecording
                ? Text("Recording...")
                : Text("Press the button to start recording"),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _isRecording ? _stopRecording : _startRecording,
              child: Text(_isRecording ? "Stop Recording" : "Start Recording"),
            ),
          ],
        ),
      ),
    );
  }
}

3. 播放音频

你可以使用 HybridMediaAudioPlayer 来播放音频文件：

import 'package:hybrid_media/hybrid_media.dart';

class AudioPlayerPage extends StatefulWidget {
  [@override](/user/override)
  _AudioPlayerPageState createState() => _AudioPlayerPageState();
}

class _AudioPlayerPageState extends State<AudioPlayerPage> {
  HybridMediaAudioPlayer _audioPlayer = HybridMediaAudioPlayer();
  bool _isPlaying = false;

  Future<void> _playAudio(String filePath) async {
    await _audioPlayer.play(filePath);
    setState(() {
      _isPlaying = true;
    });
  }

  Future<void> _pauseAudio() async {
    await _audioPlayer.pause();
    setState(() {
      _isPlaying = false;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Audio Player'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            _isPlaying
                ? Text("Playing...")
                : Text("Press the button to play audio"),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _isPlaying ? _pauseAudio : () => _playAudio("path_to_audio_file"),
              child: Text(_isPlaying ? "Pause" : "Play"),
            ),
          ],
        ),
      ),
    );
  }
}

4. 录制视频

hybrid_media 也支持视频录制。你可以使用 HybridMediaVideoRecorder 来录制视频：

import 'package:hybrid_media/hybrid_media.dart';

class VideoRecorderPage extends StatefulWidget {
  [@override](/user/override)
  _VideoRecorderPageState createState() => _VideoRecorderPageState();
}

class _VideoRecorderPageState extends State<VideoRecorderPage> {
  HybridMediaVideoRecorder _videoRecorder = HybridMediaVideoRecorder();
  bool _isRecording = false;

  Future<void> _startRecording() async {
    await _videoRecorder.startRecording();
    setState(() {
      _isRecording = true;
    });
  }

  Future<void> _stopRecording() async {
    String filePath = await _videoRecorder.stopRecording();
    setState(() {
      _isRecording = false;
    });
    print("Video saved to: $filePath");
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Video Recorder'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            _isRecording
                ? Text("Recording...")
                : Text("Press the button to start recording"),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _isRecording ? _stopRecording : _startRecording,
              child: Text(_isRecording ? "Stop Recording" : "Start Recording"),
            ),
          ],
        ),
      ),
    );
  }
}

class _VideoPlayerPageState extends State<VideoPlayerPage> {
  HybridMediaVideoPlayer _videoPlayer = HybridMediaVideoPlayer();
  bool _isPlaying = false;

  Future<void> _playVideo(String filePath) async {
    await _videoPlayer.play(filePath);
    setState(() {
      _isPlaying = true;
    });
  }

  Future<void> _pauseVideo() async {
    await _videoPlayer.pause();
    setState(() {
      _isPlaying = false;
    });
  }

            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _isPlaying ? _pauseVideo : () => _playVideo("path_to_video_file"),
              child: Text(_isPlaying ? "Pause" : "Play"),
            ),
          ],
