Getting Started
Import it
import 'package:snappable_thanos/snappable_thanos.dart';
Wrap any widget in Snappable
@override
Widget build(BuildContext context) {
  return Snappable(
    child: Text('This will be snapped'),
  );
}
Snap with a Key
class MyWidget extends StatelessWidget {
  final key = GlobalKey<SnappableState>();
  @override
  Widget build(BuildContext context) {
    return Snappable(
      key: key,
      child: Text('This will be snapped'),
    );
  }
  
  void snap() {
    key.currentState.snap();
  }
}
Undo by currentState.reset().
or snap by tap
class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Snappable(
      snapOntap: true,
      child: Text('This will be snapped'),
    );
  }
}
Undo by tapping again.
Callback for when the snap ends
class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Snappable(
      onSnapped: () => print("Snapped!"),
      child: Text('This will be snapped'),
    );
  }
}
