Can you name the three most preferred libraries for Flutter development that you use or find most useful?

1. provider — a simple and powerful state management library that integrates well with Flutter and is suitable for most applications.

2. dio — a convenient HTTP client with support for interceptors, timeouts, request cancellation, and other useful network features.

3. flutter_bloc — a library for implementing the BLoC pattern, helping to structure business logic and state management in large applications.

Example of using provider:

class Counter with ChangeNotifier {
  int _count = 0;
  int get count => _count;

  void increment() {
    _count++;
    notifyListeners();
  }
}

// In widget
Consumer<Counter>(
  builder: (context, counter, child) => Text('Count: \\${counter.count}'),
)
