Description

Removes the cross-import of TestCallbackPainter from test/rendering/rendering_tester.dart in test/cupertino/picker_test.dart, and inlines the trivial 12-line class directly in the test file.

Per the issue guidelines: "Duplicate the util if its implementation is trivial."

Tests

All existing tests continue to pass:

  • packages/flutter/test/cupertino/picker_test.dart — 27 tests pass

Code Review

This pull request removes an unused import and adds a TestCallbackPainter helper class to the Cupertino picker tests. The review feedback suggests adding documentation to the new public members to comply with the style guide and updating the shouldRepaint method signature for better consistency with Flutter's CustomPainter implementation.

Thank you for the review, @gemini-code-assist!

Both suggestions have been addressed:

  1. Doc comments added: TestCallbackPainter now has /// doc comments on the class, constructor, and onPaint field explaining their purpose.
  2. shouldRepaint signature updated: Now uses covariant TestCallbackPainter oldDelegate to match Flutter's CustomPainter convention.
