How can i print random task/item from the list in flutter?

I was wondering how can I print/display text of random item from the list? Here is the code of the list i have

class TaskData extends ChangeNotifier {
  List<Task> _tasks = [
    Task(name: "Task one"),
    Task(name: "Task two"),
    Task(name: "Task three"),
  ];

  UnmodifiableListView<Task> get tasks {
    return UnmodifiableListView(_tasks);
  }

  int get taskCount {
    return _tasks.length;
  }

Here I have different file with buttons and i managed to get some code to just test it out (Found online) but it only displays second task, doesn't randomize not sure why.

class TasksScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    List yourList = ["first item", "second item", "third item"];
    int randomIndex = Random().nextInt(yourList.length);
    return Scaffold(
      backgroundColor: Colors.lightBlueAccent,
      floatingActionButton: Row(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        children: <Widget>[
          FloatingActionButton.extended(
              label: const Text("Randomize"),
              icon: const Icon(Icons.touch_app),
              backgroundColor: Colors.lightBlueAccent,
              onPressed: () {
                print(yourList[randomIndex]);
              }),

Would really appreciate if someone could help me with this one Thank you!
