getUploadProgress method

@override Stream<double> getUploadProgress(String taskId)

Gets a stream of progress updates for an upload task.

Parameters:

@override
Stream<double> getUploadProgress(String taskId) {
  final controller = _progressControllers[taskId];
  if (controller == null) {
    throw Exception('Task not found: $taskId');
  }
  return controller.stream;
}
