Worked on the flutter/flutter repository to enhance UI customization for Material ListTile widgets using Flutter and Dart. Focused on adding new property passthroughs such as horizontalTitleGap, minVerticalPadding, minLeadingWidth, and minTileHeight to CheckboxListTile, SwitchListTile, and RadioListTile, ensuring these properties propagate correctly to the underlying ListTile. Addressed related passthrough bugs to improve stability and updated documentation and tests to cover the new features, supporting regression protection. These changes enabled more consistent UI customization and alignment across Material widgets, reducing the need for workarounds and streamlining developer workflows while maintaining design fidelity and robust widget behavior.
