Does not work with touchpad scrolling gestutre

[12people]

bottom_sheet_bar works great on touch devices. However, on desktop devices, it only works with the click-and-drag gestures — trackpad scrolling is not supported.

This is because, as of version 3.3.0, Listener has had new PointerEvents introduced specifically for trackpads and the older events no longer work with them — see the Flutter documentation.

It'd be great if the bottom sheet could be shown via an upward scroll gesture even in newer Flutter versions.
