fluttersnowboy's Issues

Unable to init Snowboy, required bundled file 'common.res' missing

Hi there,

Thanks for making this package, but I haven't get it working till now, always got 'common.res' missing problem. I downloaded the file from https://github.com/Kitt-AI/snowboy/blob/master/resources/common.res and load it in runtime as well.

What I did:

1. install all packages
2. put the pmdl file , common.res , ding.wav in the root's assets folder and declared in pubspec.yml

flutter:
  assets:
     - assets/yoyo.pmdl
     - assets/common.res 
     - assets/ding.wav

The code is learned from the example in https://pub.dev/packages/flutter_snowboy

...

    final directory = await getApplicationDocumentsDirectory();
    final modelPath = "${directory.path}/yoyo.pmdl";
    final commonResPath = "${directory.path}/common.res";
    
    final bytes = await rootBundle.load("assets/yoyo.pmdl");
    final modelData = bytes.buffer.asUint8List();
    await File(modelPath).writeAsBytes(modelData);
    debugPrint('>>> modelPath: $modelPath'); 

    final commonResBytes = await rootBundle.load("assets/common.res");
    final commonResData = commonResBytes.buffer.asUint8List();
    await File(commonResPath).writeAsBytes(commonResData);
    debugPrint('>>> commonResPath: $commonResPath');

    detector = Snowboy();
    await detector.prepare(modelPath); // working, otherwise, it will show the model missing
    detector.hotwordHandler = hotwordHandler;
    await configureAudioSession();
...

The console display:

flutter: >>> modelPath: /var/mobile/Containers/Data/Application/46445C07-C970-468C-B548-D63578DC4BC3/Documents/yoyo.pmdl
flutter: >>> commonResPath: /var/mobile/Containers/Data/Application/46445C07-C970-468C-B548-D63578DC4BC3/Documents/common.res
Unable to init Snowboy, required bundled file 'common.res' missing

I found the similar discussion here: Kitt-AI/snowboy#309
But I don't find a way to pass the common.res path in this lib.
