使用Flutter实现 仿微信录音的插件

插件支持android 和IOS


插件提供的功能 录制

  1. 录制语音,
  2. 播放录音,
  3. 录制声音大小的监听
  4. 提供录制时长的监听
  5. 提供类似微信的录制组件
  6. 提供播放音频结束的监听
  7. 提供根据传递的路径进行语音录制
  8. 提供录制wav,mp3格式 具体可参考example

播放

  1. 提供播放指定路径的音频文件
  2. 提供播放指定Url地址的wav,MP3格式文件
  3. 提供播放完成的回调监听
  4. 提供暂停和继续播放的功能
  5. 提供停止播放的功能

1,引入

在pubspec.yaml 文件上引入如下配置

引入方式1(引入最新的版本)
flutter_plugin_record:
    git:
      url: https://github.com/yxwandroid/flutter_plugin_record.git

引入方式2 (引入指定某次commit)
flutter_plugin_record:
    git:
      url: https://github.com/yxwandroid/flutter_plugin_record.git
      ref: 29c02b15835907879451ad9f8f88c357149c6085
      
引入方式3 (引入Flutter仓库的library)
      
dependencies:
  flutter_plugin_record: ^1.0.1

使用

1, 初始化录制

1.1, 初始化录制(wav)

可以在页面初始化的时候进行初始化比如: 在initState方法中进行初始化

//实例化对象 
FlutterPluginRecord   recordPlugin = new FlutterPluginRecord();
//    初始化
recordPlugin.init()

1.2, 初始化录制(Mp3)

可以在页面初始化的时候进行初始化比如: 在initState方法中进行初始化

//实例化对象 
FlutterPluginRecord   recordPlugin = new FlutterPluginRecord();
//    初始化
recordPlugin.initRecordMp3()

2, 开始录制

 recordPlugin.start()

3, 停止录制

 recordPlugin.stop()

4, 播放

1,播放

 recordPlugin.play()

2, 暂停和继续播放

 recordPlugin.pausePlay();

3, 停止播放

 recordPlugin.stopPlay();

5, 根据传递的路径进行语音录制

 recordPlugin.startByWavPath(wavPath);

6, 根据传递的路径或则Url进行语音播放

  ///
  /// 参数 path  播放音频的地址
  ///
  ///path 为 url类型对应的在线播放地址   https://linjuli-app-audio.oss-cn-hangzhou.aliyuncs.com/audio/50c39c768b534ce1ba25d837ed153824.wav
  ///path 对应本地文件路径对应的是本地文件播放肚子   /sdcard/flutterdemo/wiw.wav
  /// 参数  type
  /// 当path 为url   type为 url
  /// 当path 为本地地址 type为 file
  ///
  Future playByPath(String path, String type) async {
    return await _invokeMethod('playByPath', <String, String>{
      "play": "play",
      "path": path,
      "type": type,
    });
  }   

7, 释放资源

可以在页面退出的时候进行资源释放 比如在 dispose方法中调用如下代码

 recordPlugin.dispose()

4,回调监听

1,初始化回调监听

///初始化方法的监听
recordPlugin.responseFromInit.listen((data) {
  if (data) {
    print("初始化成功");
  } else {
    print("初始化失败");
  }
});

2,开始录制停止录制监听

 /// 开始录制或结束录制的监听
    recordPlugin.response.listen((data) {
      if (data.msg == "onStop") {
        ///结束录制时会返回录制文件的地址方便上传服务器
        print("onStop  " + data.path);
      } else if (data.msg == "onStart") {
        print("onStart --");
      }
    });

3,录制声音大小回调监听

 ///录制过程监听录制的声音的大小 方便做语音动画显示图片的样式
    recordPlugin.responseFromAmplitude.listen((data) {
      var voiceData = double.parse(data.msg);
      var tempVoice = "";
      if (voiceData > 0 && voiceData < 0.1) {
        tempVoice = "images/voice_volume_2.png";
      } else if (voiceData > 0.2 && voiceData < 0.3) {
        tempVoice = "images/voice_volume_3.png";
      } else if (voiceData > 0.3 && voiceData < 0.4) {
        tempVoice = "images/voice_volume_4.png";
      } else if (voiceData > 0.4 && voiceData < 0.5) {
        tempVoice = "images/voice_volume_5.png";
      } else if (voiceData > 0.5 && voiceData < 0.6) {
        tempVoice = "images/voice_volume_6.png";
      } else if (voiceData > 0.6 && voiceData < 0.7) {
        tempVoice = "images/voice_volume_7.png";
      } else if (voiceData > 0.7 && voiceData < 1) {
        tempVoice = "images/voice_volume_7.png";
      }
      setState(() {
        voiceIco = tempVoice;
        if(overlayEntry!=null){
          overlayEntry.markNeedsBuild();
        }
      });

      print("振幅大小   " + voiceData.toString() + "  " + voiceIco);
    });

4,播放声音完成的监听监听

  recordPlugin.responsePlayStateController.listen((data){
  print("播放路径   " + data.playPath );
  print("播放状态   " + data.playState );
});

2,录制组件的使用

组件使用效果

android效果

IOS效果

1,在使用的页面进行导入package

import 'package:flutter_plugin_record/index.dart';  

2,在使用的地方引入VoiceWidget组件

VoiceWidget(),


VoiceWidget({startRecord: Function, stopRecord: Function}) {

startRecord 开始录制的回调

stopRecord 停止录制的回调 返回的path是录制成功之后文件的保存地址

IOS配置注意事项

ios集成的的时候需要在info.list添加

 <key>NSMicrophoneUsageDescription</key>
        <string>打开话筒</string>


 <key>NSAppTransportSecurity</key>
 	<dict>
 		<key>NSAllowsArbitraryLoads</key>
 		<true/>
 	</dict>

ios release 打包失败配置注意事项

android配置注意事项

android 集成的的时候需要在application标签下添加

  tools:replace="android:label"

###iOS 中断切换后台一些优化

FlutterPluginRecordPlugin 回主线程重启录音 [DPAudioRecorder.sharedInstance performSelectorOnMainThread:@selector(startRecording) withObject:nil waitUntilDone:NO];

DPAudioRecorder [self.audioRecorder record]; 改为 [self.audioRecorder recordAtTime:200] 延迟200毫秒启动;

被中断后 调用[self clean] 把audioRecorder 销毁置为 nil

TODO

  • 双声道切换 单声道切换
