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) {
                print(index);
              },
              onEnd: () {
                print('end');
              },
            ),
            SizedBox(
              height: 40,
            ),
            Row(
              mainAxisAlignment: MainAxisAlignment.spaceAround,
              children: <Widget>[
                OutlineButton(
                  onPressed: () {
                    print(_controller);
                    _controller.back();
                  },
                  child: Text('Back'),
                ),
                OutlineButton(
                  onPressed: () {
                    _controller.reset();
                  },
                  child: Text('Reset'),
                ),
                OutlineButton(
                  onPressed: () {
                    _controller.forward();
                  },
                  child: Text('Forward'),
                ),
              ],
            ),
          ],
        ),
      ),
    );
  }
}

Determine the sliding direction

 TCard(
  cards: cards,
  size: Size(360, 480),
  controller: _controller,
  onForward: (index, info) {
    print(index);
    print(info.direction);
    if (info.direction == SwipDirection.Right) {
      print('like');
    } else {
      print('dislike');
    }
  },
  onBack: (index, info) {
    print(index);
  },
  onEnd: () {
    print('end');
  },
)

Reset width new cards

List<Widget> newCards = [];

TCardController _controller = TCardController();

_controller.reset(cards: newCards);
