Flutter / Dart-首次构建时Android Manifest权限使App崩溃

如何解决Flutter / Dart-首次构建时Android Manifest权限使App崩溃

在Android Studio中首次构建我的应用程序时发生了一些奇怪的事情。接受以下权限的“允许”后，该应用程序将崩溃，并且无法完全加载到我的手机上。

Allow YourApp to access photos and media on your device?
Allow YourApp to record audio?

但是当我再次尝试构建时，它已完全加载并且第二次运行正常。

这是我的AndroidManifest.xml中的内容；

 <uses-permission android:name="android.permission.RECORD_AUdio"/>
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.WAKE_LOCK" />
 <uses-permission android:name="android.permission.INTERNET"/>

这是我要求记录许可的地方；

_init() async {
try {
  setState(() {
    stopButton = false;
    playButton = false;
    recButton = true;
  });
  if (await FlutterAudioRecorder.hasPermissions) {
    String customPath = '/Flutter_audio_recorder_';
    io.Directory appDocDirectory;
    if (io.Platform.isIOS) {
      appDocDirectory = await getApplicationDocumentsDirectory();
    } else {
      appDocDirectory = await getExternalStorageDirectory();
    }
    customPath = appDocDirectory.path +
        customPath +
        DateTime.Now().millisecondsSinceEpoch.toString();
    _recorder = FlutterAudioRecorder(customPath,audioFormat: AudioFormat.AAC,sampleRate: 44100);

    await _recorder.initialized;
    var current = await _recorder.current(channel: 0);

     setState(() {
      _current = current;
      _currentStatus = current.status;
    });
  } else {
    Scaffold.of(context).showSnackBar(
        new SnackBar(content: new Text("You must accept permissions")));
  }
} catch (e) {
  print(e);
 }
}

有人知道为什么我第一次尝试构建时会崩溃吗？
