Have you worked with dependency injection mechanisms in projects?

Dependency Injection (DI) in Flutter helps manage dependencies between objects, making testing and maintaining code easier. Commonly, packages like provider, get_it, or riverpod are used.

Example using get_it:

import 'package:get_it/get_it.dart';

final getIt = GetIt.instance;

class ApiService {
  void fetchData() {
    print('Fetching data...');
  }
}

void setup() {
  getIt.registerLazySingleton<ApiService>(() => ApiService());
}

void main() {
  setup();
  var api = getIt<ApiService>();
  api.fetchData();
}

This approach allows centralized management of dependencies and easy replacement of implementations, for example, for testing.
