आप नीचे पेस्ट रन पूरा कोड कॉपी कर सकते हैं
आप StatefulWidget का उपयोग कर सकते हैं और setState को onTap
के अंदर कॉल कर सकते हैं सांकेतिक टुकड़ा

class _ListTileCustomState extends State<ListTileCustom> {
  String _title = "title";
  Color _color = Colors.blue;

  @override
  Widget build(BuildContext context) {
    return ListTile(
      tileColor: _color,
      leading: GestureDetector(
          behavior: HitTestBehavior.translucent,
          onTap: () {
            setState(() {
              _title = "changed";
              _color = Colors.red;
            });
          },
          child: Icon(Icons.add)),
      title: Text(_title),
      dense: false,
    );
  }
}
