I emplacements the script on ionic 5 and it is so beautiful.

Thanks

Also can you add more function like backdropClose like ability to change the pane to any Breakpoints.
for example if the pane on top and when i click on backdrop drop, will minimize the pane to bottom or middle based on my choice on settings.

Updated package, now you can make this

let settings = {
  ...
  backdropTransparent: true,
  onBackdropTap: () => {
    this.cupertinoPane.moveToBreak('bottom');
  }
}

Or this

let settings = {
  ...
  backdropTransparent: true,
  onBackdropTap: () => {
    this.cupertinoPane.destroy({animate: true});
  }
}

Nice work, and thanks so much for fast response. It’s working pretty good on actual devices.
