GitAuto: Add a widget test for lib/components/button/gf_button.dart

[gitauto-ai]

Resolves #27

Why is this feature needed?

Widget testing is essential to ensure that UI components behave as expected without manual intervention. In this case, adding tests for GFButton helps to catch regressions and verify that the button functions correctly in both enabled and disabled states.

What and how are we changing? Why this approach?

We have introduced a new test file, "test/components/button/gf_button_test.dart", which contains two test cases:

• The first test ensures that GFButton renders with the correct text and properly executes its onPressed callback when tapped.
• The second test verifies that a GFButton with a null onPressed (disabled state) renders correctly and does not trigger any actions upon tapping.
  This approach leverages Flutter's widget testing capabilities to simulate user interaction and validate the widget behavior in isolation.

What actions are required from users?

No user action is required. This change only impacts the test suite. It is recommended that developers run the tests locally or via the CI pipeline to ensure everything works as expected.

How does it work? (Technical details)

• The tests use Flutter's built-in testing framework (flutter_test) to create a simulated environment.
• Each test wraps the GFButton in a MaterialApp and a Scaffold to mimic the real app context.
• The first test modifies a boolean flag to confirm that the onPressed event is fired when the button is tapped.
• The second test confirms that the button is correctly rendered with the disabled state by setting onPressed to null and ensuring no unintended interactions occur.

Is it backwards compatible?

Yes, this change is fully backwards compatible as it only adds new test cases and does not modify the existing functionality of the GFButton widget.

Any other considerations?

• These tests help ensure that any future modifications to the GFButton component will be less likely to introduce regressions.
• Additional tests can be added in the future to cover more edge cases or additional features/functions of the GFButton if needed.
• Regular test runs via CI/CD are recommended to maintain code quality and catch issues early in the development process.
