How do you widget-test states without real network calls?
This tests UI isolation from I/O. Mock the repository with Mockito, stub methods to yield loading, success, and error, and inject it via constructor or provider. Avoid real HTTP calls or unmocked clients in widget tests.
This tests whether you can isolate widget tests from external I/O using dependency injection and mocking. Generate a mock repository with Mockito, then stub its methods to synchronously or asynchronously return loading, success, and error states. Inject the mock into the widget tree via the constructor or an inherited provider, pump the tester, and verify that the correct UI elements appear for each state. Never make real network calls, use unmocked HTTP clients, or rely on global singletons that cannot be overridden in tests.
