我设法使用本机代码完成了它

首先，您将在 Flutter 端创建这些东西。


// here where your ringtones will be stored
List<Object?> result = ['Andromeda'];

// this is the channel that links flutter with native code
static const channel = MethodChannel('com.example.pomo_app/mychannel');

// this method waits for results from the native code 
Future<void> getRingtones() async {
    try {
      result = await channel.invokeMethod('getAllRingtones');
    } on PlatformException catch (ex) {
      print('Exception: $ex.message');
    }
  }

知道你需要实现本机代码。转到 MainActivity.kt

// add the name of the channel that we made in flutter code
private val channel = "com.example.pomo_app/mychannel"

// add this method to handle the calls from flutter
MethodChannel(flutterEngine.dartExecutor.binaryMessenger, channel)
  .setMethodCallHandler { call, result ->
            when (call.method) {
                "getAllRingtones" -> {
                    result.success(getAllRingtones(this))
                }



// this function will return all the ringtones names as a list
private fun getAllRingtones(context: Context): List<String> {

  val manager = RingtoneManager(context)
  manager.setType(RingtoneManager.TYPE_RINGTONE)

  val cursor: Cursor = manager.cursor

  val list: MutableList<String> = mutableListOf()
  while (cursor.moveToNext()) {
    val notificationTitle: String = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX)
    list.add(notificationTitle)
  }
  return list
}

就是这样，希望对您有所帮助。任何问题让我知道。
