ListTile's tileColor and selectedTileColor are not working in Flutter / Dart

I have upgraded Flutter version on my Windows 10 system. flutter upgrade command installed Flutter's 2.5.0-5.2.pre version on system.

My existing project has many ListTile widgets on various screens / pages. I am attaching below code snippets.

Code 1:

ListTile(
  tileColor: Color.fromRGBO(255, 255, 0, 1),
  selected: true,
  selectedTileColor: Color.fromRGBO(255, 0, 255, 1),
  title: Text('Hello friends'),
),

Code 2:

ListTile(
  tileColor: Colors.green,
  selected: true,
  selectedTileColor: Colors.red,
  title: Text('Hello friends'),
),

Is there anyone who can help me to understand why are ListTile's tileColor and selectedTileColor not working in Flutter / Dart after upgrading flutter? Any help will be appreciated. Thanks a lot.
