解决方案

You could use library flip_card.

Add this to pubspec.yaml :

dependencies:
  flip_card: ^0.4.4

Then run

flutter packages get

To use :

import 'package:flip_card/flip_card.dart';

FlipCard(
  direction: FlipDirection.HORIZONTAL, // default
  front: Container(
        child: Text('Front'),
    ),
    back: Container(
        child: Text('Back'),
    ),
);
