Use a controller to control

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  TCardController _controller = TCardController();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            TCard(
              cards: cards,
              size: Size(360, 480),
              controller: _controller,
              onForward: (index, info) {
                print(index);
              },
              onBack: (index, info) {
