AiryBottomSheet

Thanks for looking!

WHAT'S THIS?

AiryBottomSheet is a very easy-to-use and stylish BottomSheet that seamlessly switches widgets by scrolling through the BottomSheet and adjusts like a magnet to the specified height when released.

HOW TO USE (Only 3 steps!)

1. Defines widgets wrapped in a Handle.

The Handle widget is required to adjust the height of the AiryBottomSheet.

Widget _firstChild() {
  return Column(
    children: [
      Handle(
        controller: _controller,
        child: Container(
          color: Colors.redAccent,
          height: 40,
        ),
      ),
      Expanded(
        child: Container(
          color: Colors.black,
        ),
      )
    ],
  );
}

Widget _secondChild() {
  return Handle(
    controller: _controller,
    child: Column(
      children: [
        Expanded(
          child: Container(
            color: Colors.red,
          ),
        ),
      ],
    ),
  );
}

2. Prepare AiryBottomSheetController

• initialHeight is the initial height of the AiryBottomSheet.
• magnetPoints is the height that is adjusted when the scroll is released.
  • -> why the type of magnetPoints is List<List<double>> ??
    • This is in contrast to AiryBottomSheet.switchChildren described below, which uses the information in the corresponding index to determine the widget and height to be displayed.
• maxHeight is the maximum height of the AiryBottomSheet.
• minHeight is the minimum height of the AiryBottomSheet.

final _controller = AiryBottomSheetController(
  initialHeight: 100,
  magnetPoints: [
    [100],
    [200, 300],
    [400, 500],
  ],
  maxHeight: 530,
  minHeight: 80,
);

3. Call your AiryBottomSheet

• _scaffoldKey is GlobalKey<ScaffoldState>.
• controller is prepared in Section 2.
• switchChildren is paired with AiryBottomSheetController.magnetPoints and the corresponding index height and widget will be displayed on the AiryBottomSheet.
• onDragAndAnimationEnd is literal. :)✨

AiryBottomSheet.show(
  _scaffoldKey,
  controller: _controller,
  switchChildren: [
    _firstChild(),
    _secondChild(),
    _thirdChild(),
  ],
  onDragAndAnimationEnd: (height) {
    debugPrint(height.toString());
  },
);
