Flutter：如何将麦克风的原始音频信号实时存储到内存中？

您可以使用颤动声音插件将麦克风的原始音频信号实时存储到内存中。参考链接是：https : //pub.dev/packages/flutter_sound和演示示例在这里https://github.com/dooboolab/flutter_sound/blob/master/example/lib/demo_util/demo3_body.dart

我有一个例子是

Widget _buildRecorder(Track track) {
    return Padding(
        padding: const EdgeInsets.all(8.0),
        child: RecorderPlaybackController(
            child: Column(
          children: [
            Left("Recorder"),
            SoundRecorderUI(track),
            Left("Recording Playback"),
            SoundPlayerUI.fromTrack(
              track,
              enabled: false,
              showTitle: true,
              audioFocus: true
                  ? AudioFocus.requestFocusAndDuckOthers
                  : AudioFocus.requestFocusAndDuckOthers,
            ),
          ],
        )));
  }

}

谢谢。
