Issues with ArrayBuffer in Flutter Web

[beevelop]

When using Socket.io with Flutter Web and sending ArrayBuffers over the pipe, the browser throws the following exception:

Uncaught Error: NoSuchMethodError: '[]'
Dynamic call of null.
Receiver: Instance of 'NativeByteBuffer'
Arguments: [0]
    at Object.throw_ [as throw] (errors.dart:196)

I saw, that the required code portion is in place, but unfortunately commented out.

if (data instanceof ArrayBuffer) {
  data = arrayBufferToBuffer(data);
}

https://github.com/rikulo/socket_io_common/blob/master/lib/src/engine/parser/parser.dart#L167

I tried adapting the implementation to automatically detect the ArrayBuffer, and it seems to (at least) stop throwing exceptions:

    if (binaryType == 'arraybuffer' || runtimeType == 'ByteBuffer') { //  || data.runtimeType == 'NativeByteBuffer'
      // wrap Buffer/ArrayBuffer data into an Uint8Array
      var intArray = (data as ByteBuffer).asUint8List();
      type = intArray[0];
      return {'type': PacketTypeList[type], 'data': intArray.sublist(0)};
    }

Would this be a suitable approach?

@beevelop please upgrade the socket_io_common to 0.9.1 to see if the fix works, thanks.
