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

  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

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: ^0.0.9

使用 #

1, 初始化录制 #

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()

2, 开始录制 #

 recordPlugin.start()

3, 停止录制 #

 recordPlugin.stop()

4, 播放 #

 recordPlugin.play()

3, 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);
    });

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>

  • 实现录制时长的监听

TODO #

  • 实现发送语音时间按下抬起时间很短提示
