Mocking Flutter/Dart tests often requires code generation or heavy boilerplate. Mocktail provides a no-codegen approach and guides when to use mocks, fakes, or real objects to keep tests fast and readable.
Create mocks by extending Mock and implementing your service, then stub methods with when and thenReturn and verify interactions.

Mock Dart and Flutter tests without code generation by extending the Mock class and implementing your service. Mocktail uses a noSuchMethod approach to stub methods and verify interactions, keeping tests fast and readable.
Stub method responses in Dart unit testing using when and thenReturn or thenAnswer. Verify interactions using verify, verifyNever, and called(n), applying argument matchers like any and captureAny for flexible assertions.
Register fallback values in Mocktail when using argument matchers with non-nullable custom types. This requirement ensures the testing framework has valid default instances to satisfy Dart's null safety constraints during method stubbing and verification.
Use mocks, fakes, or real objects in Flutter widget testing based on your needs: mocks verify interactions via noSuchMethod, fakes provide lightweight implementations, and real objects execute actual logic to ensure accurate behavior.
Yes, Mocktail works with both unit and widget testing in Dart and Flutter. It covers mocking, stubbing, and interaction verification across both testing scopes without requiring code generation or heavy boilerplate.
