audio - FLUTTER:我想录制麦克风流并立即播放

Question

我想做和申请谁来使用麦克风流，并直接在Flutter中播放它，谁可以帮助我，我在Internet上一无所获。谢谢!

Answer 1

您可以使用this库记录麦克风的音频。

用法
要使用此插件，请将audio_recorder作为依赖项添加到pubspec.yaml文件中。

Android

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

iOS

<key>NSMicrophoneUsageDescription</key>
<string>Record audio for playback</string>

示例

// Import package
import 'package:audio_recorder/audio_recorder.dart';

// Check permissions before starting
bool hasPermissions = await AudioRecorder.hasPermissions;

// Get the state of the recorder
bool isRecording = await AudioRecorder.isRecording;

// Start recording
await AudioRecorder.start(path: _controller.text, audioOutputFormat: AudioOutputFormat.AAC);

// Stop recording
Recording recording = await AudioRecorder.stop();
print("Path : ${recording.path},  Format : ${recording.audioOutputFormat},  Duration : ${recording.duration},  Extension : ${recording.extension},");

现在，您需要做的就是播放录制的声音文件。
