How can you track component state updates in the BLoC architecture?

In the BLoC (Business Logic Component) architecture, the component's state is usually stored as a stream. To track state updates, you need to subscribe to this stream using the listen method or use widgets that automatically subscribe to the stream, such as StreamBuilder in Flutter.

Example of using StreamBuilder to monitor BLoC state:

StreamBuilder<MyState>(
  stream: myBloc.stateStream,
  builder: (context, snapshot) {
    if (snapshot.hasData) {
      return Text('Current state: \\${snapshot.data}');
    } else {
      return CircularProgressIndicator();
    }
  },
)

Thus, with each state update of the BLoC, the widget will automatically rebuild with the new state.
