================================================ [TOC] # 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', { "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 NSMicrophoneUsageDescription 打开话筒 NSAppTransportSecurity NSAllowsArbitraryLoads ### 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" ## TODO * [ ] 双声道切换 单声道切换 ## 感谢 [肖中旺](https://github.com/xzw421771880)对IOS 播放在线Wav的支持 ## 作者的其他开源项目推荐 [基于腾讯云点播封装的flutter版的播放器插件

FILE: example/README.md ================================================ # flutter_plugin_record_example ### 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 暂停,停止播放 #### 1,播放 recordPlugin.play() #### 2, 暂停和继续播放 recordPlugin.pausePlay(); #### 3, 停止播放 recordPlugin.stopPlay(); ### 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 ### 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 new VoiceWidget(), ## TODO * [x] 实现发送语音时间按下抬起时间很短提示 * [x] 优化代码 * [x] 实现录制完成文件路径回调功能,方面使用者可以把录音文件上传服务器 ## 关注公众号获取更多内容
