Getting Started

Import it

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'),
    );
  }
}
