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

It's not ListTile that has the style property. But ListTileTheme. ListTileTheme is an inheritedWidget. And like others, it's used to pass down data (such as theme here).

To use it, you have to wrap any widget above your ListTile with a ListTileTheme containing the desired values.

ListTile will then theme itself depending on the closest ListTileTheme instance.
