[HELP]:Cache size increases every time mPlayer!.startPlayer fromDataBuffer is called

[changcw83]

// any mp3 buffer
mPlayer!.startPlayer(
        fromDataBuffer: buffer,
        codec: Codec.mp3,
);

Are there any ways to deal with this cache "leak"

I have tried to clear cache programmatically by doing this.

    import 'package:path_provider/path_provider.dart';
    //then
    final cacheDir = await getTemporaryDirectory();
    if (cacheDir.existsSync()) {
      cacheDir.deleteSync(recursive: true);
    }

but after doing so and running the startPlayer method I get the following error

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(ERR_UNKNOWN, ERR_UNKNOWN, startPlayer() error, null)

Hi Chang. How are you doing? This is probably a bug in Flutter Sound. I am going to fix that this week.

iOS or Android or both? Which codec?

Cheers my friend.

[changcw83]

noticed on android not sure how to check cache size on iOS will get my wife's phone tonight. codec is mp3 flutter_sound 9.1.3

[changcw83]

Found a workaround. Use the following function to "copy" the asset to cacheDir then use fromURI

  Future<File> assetToFile(String path) async {
    final byteData = await rootBundle.load('assets/$path');
    var tempDir = (await getTemporaryDirectory()).path;
    final file = File('$tempDir/$path');
    await file.writeAsBytes(byteData.buffer
        .asUint8List(byteData.offsetInBytes, byteData.lengthInBytes));
    return file;
  }
  // then call mPlayer!.startPlayer(fromURI:...)
