NoDirectInstantiation class

Enforces dependency injection for better testability of auth/sync components.

This rule flags all direct instantiations of classes, except:

  • Classes whose names end with 'Factory' (e.g., FileProcessorFactory)
  • Classes that extend 'Module'
  • Any instantiation that occurs inside a class that extends 'Module'

Example:

// ❌ Not allowed:
fakeSupabaseWrapper = FakeSupabaseWrapper();
final service = AuthService();

// ✅ Allowed:
fakeSupabaseWrapper = Modular.get<FakeSupabaseWrapper>();
final service = Modular.get<AuthService>();
final factory = FileProcessorFactory();
final module = AppModule();

// ✅ Allowed: Instantiation inside a Module
class AppModule extends Module {
  AppModule() {
    final service = AuthService(); // Allowed here
  }
}
