Change background color of ListTile upon selection in Flutter

Question

I've made a ListView in Flutter, but now I have some ListTiles in this ListView that can be selected. Upon selection, I want the background color to change to a color of my choice. I don't know how to do that. In the docs they mention that a ListTile has a property style. However, when I try to add that (as in third last line in the code below), this style property gets a squiggly red line underneath and the compiler tells me that The named parameter 'style' isn't defined.

Widget _buildRow(String string){
  return new ListTile(
    title: new Text(string),
    onTap: () => setState(() => toggleSelection(string)),
    selected: selectedFriends.contains(string),
    style: new ListTileTheme(selectedColor: Colors.white,),
  );
}

Answer 1

I was able to change the background color of the ListTile using a BoxDecoration inside Container:

ListView (
    children: <Widget>[
        new Container (
            decoration: new BoxDecoration (
                color: Colors.red
            ),
            child: new ListTile (
                leading: const Icon(Icons.euro_symbol),
                title: Text('250,00')
            )
        )
    ]
