What methods and steps do you use for developing and implementing project solutions?

To develop and implement solutions in a Flutter project, I usually follow these steps:

1. Requirements analysis — carefully study the task, clarify details and expected results.
2. Architecture planning — choose an appropriate pattern (e.g., BLoC, Provider, MVVM) and break down the task into modules.
3. UI prototyping — create basic widgets to visualize the interface.
4. Logic implementation — write business logic, integrate with backend or local data.
5. Testing — add unit and widget tests to verify correctness.
6. Optimization and refactoring — improve performance and code readability.
7. Deployment and monitoring — prepare the build and track app behavior.

Example of a simple widget using Provider for state management:

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

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

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