Make sure that a ListTile doesn't crash in 0x0 environment

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

Code Review

This pull request adds a regression test to ensure that ListTile does not crash when rendered in a zero-sized area. My review includes a suggestion to make the test more comprehensive by covering more ListTile configurations to prevent future regressions.

This test is a good start for ensuring ListTile behaves correctly in a zero-sized environment. However, it only covers the case of an empty ListTile. The layout logic for ListTile can be more complex when it includes leading, trailing, or title widgets.

To make this test more robust and prevent future regressions, I suggest expanding it to cover these cases as well. A table-driven approach could be effective here.

  testWidgets('ListTile does not crash at zero area', (WidgetTester tester) async {
    final List<Widget> listTiles = <Widget>[
      const ListTile(),
      const ListTile(title: Text('title')),
      const ListTile(leading: Icon(Icons.add)),
      const ListTile(trailing: Icon(Icons.remove)),
      const ListTile(leading: Icon(Icons.add), trailing: Icon(Icons.remove)),
    ];

    for (final Widget listTile in listTiles) {
      await tester.pumpWidget(
        MaterialApp(
          home: Scaffold(
            body: Center(child: SizedBox.shrink(child: listTile)),
          ),
        ),
      );
      expect(tester.getSize(find.byType(ListTile)), Size.zero, reason: 'Failed for $listTile');
    }
  });

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
