Mocktail is a Dart mocking library designed to simplify unit testing with null safety support. It eliminates the need for manual mock creation or code generation, allowing developers to create mocks dynamically at runtime. With intuitive syntax and seamless integration into test suites, Mocktail enhances test readability and maintainability. It supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux, making it ideal for cross-platform Flutter applications. The library is maintained by felangel.dev and is widely adopted in the Flutter community for its ease of use and reliability.
