Make sure that an InputChip doesn't crash in 0x0 environment

This is my attempt to handle #6537 for the InputChip widget.

Code Review

This pull request adds a regression test to ensure that InputChip does not crash when rendered in a zero-sized environment. The test is well-structured and covers the basic case. I've suggested an improvement to make the test more comprehensive by covering additional InputChip configurations, such as those with an avatar or a delete icon, to prevent future regressions.

This is a good test for the base case. To make it more robust and prevent future regressions, consider expanding it to cover more InputChip configurations. Specifically, testing with an avatar and an onDeleted callback (which adds a delete icon) would ensure that other chip layouts also handle the zero-sized environment correctly. A helper function can be used to avoid code duplication.

  testWidgets('InputChip does not crash at zero area', (WidgetTester tester) async {
    Future<void> testChip(Widget chip) async {
      await tester.pumpWidget(
        MaterialApp(
          home: Scaffold(
            body: Center(
              child: SizedBox.shrink(child: chip),
            ),
          ),
        ),
      );
      expect(tester.getSize(find.byType(InputChip)), Size.zero);
    }

    await testChip(const InputChip(label: Text('X')));
    await testChip(const InputChip(label: Text('X'), avatar: CircleAvatar(child: Text('A'))));
    await testChip(InputChip(label: const Text('X'), onDeleted: () {}));
  });

Checklist:

• The test is in the correct file
• The test name goes “does not crash at zero area”
• The target widget is wrapped by Center (or is fullscreen)
• The target widget does not have an overlay, or the overlay is tested
• The target widget is expected to have a size of exactly Size.zero
