What is the difference between widget tests and unit tests in the development process?

Unit tests check individual functions or classes in isolation, without depending on UI or external components. They are fast and help ensure that the logic works correctly.

Widget tests in Flutter verify the interaction and display of UI components (widgets). They run in an environment close to a real app and can check how widgets respond to events, change state, and display data.

Thus, unit tests focus on logic, while widget tests focus on UI and component interaction.
