Thanks for providing the library! It's very smooth and easy to integrate.

One issue we found is the onDismiss function, swiping down won't dismiss the bottom sheet where tapping the backdrop works (same for the project example listed above), and see some JavaScript error about the find the snap point.

Thanks!
