## Structuring Code for Testability
Design Dart classes to support dependency injection. Isolate complex external dependencies (like API clients or databases) so they can be replaced with mock objects during testing.

- Inject external services (e.g., `http.Client`) through class constructors.
- Represent URLs strictly as `Uri` objects using `Uri.parse(string)`.
