Reset a List when finished - flutter

Question

I have a list of strings that are rendered in swipeable cards. What I want to achieve is that when the users finishes the cards, There is a button to "retry again" and the list of Strings is reset and retrieved again.
This is what i achieved so far:
class _ExampleHomePageState extends State<ExampleHomePage> with TickerProviderStateMixin {
List<String> truths = [
"Hello",
"Hello2",
"Hello3",
"Hello4",
"Hello5",
"Hello6",
"Hello7",
"Hello7",
"Hello7",
"Hello7",
];
#override
Widget build(BuildContext context) {
CardController controller;
return Scaffold(
backgroundColor: Colors.black45,
appBar: AppBar(
centerTitle: true,
backgroundColor: Colors.white,
title: Text(
'The truth game',
style: TextStyle(color: Colors.redAccent),
),
),
body: Container(
height: MediaQuery.of(context).size.height * 0.7,
child: TinderSwapCard(
orientation: AmassOrientation.BOTTOM,
totalNum: 6,
stackNum: 4,
swipeEdge: 4.0,
maxWidth: MediaQuery.of(context).size.width * 0.9,
maxHeight: MediaQuery.of(context).size.width * 0.9,
minWidth: MediaQuery.of(context).size.width * 0.8,
minHeight: MediaQuery.of(context).size.width * 0.8,
cardBuilder: (context, index) => Card(
child: Center(
child: Text(
'${truths[index]}',
style: TextStyle(fontWeight: FontWeight.bold, fontSize: 20),
)),
),
cardController: controller = CardController(),
swipeUpdateCallback: (DragUpdateDetails details, Alignment align) {
if (align.x < 0) {
} else if (align.x > 0) {
return {
};
}
},
swipeCompleteCallback: (CardSwipeOrientation orientaion, int index) {
GestureDetector(
child: Text('try me again'),
onTap: (){
},
);
},
)),
bottomNavigationBar: CurvedNavigationBar(
color: Colors.white,
backgroundColor: Colors.transparent,
buttonBackgroundColor: Colors.white,
height: 70.0,
items: <Widget>[
Icon(
Icons.home,
size: 30.0,
color: Colors.redAccent,
),
Icon(
Icons.chat_bubble,
size: 30.0,
color: Colors.redAccent,
),
Icon(
FontAwesomeIcons.heart,
size: 30.0,
color: Colors.redAccent,
),
],
),
);
}
}
I tried setting the SetState(){} method, but its not reseting the list.

Answer 1

you can reset your whole widget by :
void _reset() {
Navigator.pushReplacement(
context,
PageRouteBuilder(
transitionDuration: Duration.zero,
pageBuilder: (_, __, ___) => MyWidget(),
),
);
}
and call it when you press your resetbutton

Answer 2

swipeCompleteCallback: (CardSwipeOrientation orientaion, int index) {
GestureDetector(
child: Text('try me again'),
onTap: (){
// add this code inside try me again..,
truths.clear();
setState((){});
},
);
},
