ui-material-components: Bottom sheet visuals ara bad and crashes on iOS

Runs great on Android but when tested on iOS i have three problems:

• Setting a background makes the view have an up and bottom white space (doesn’t happen on Android)
• When opening the view inmediatelly when the view is loaded and trying to close it gives the error: Trying to hide bottom-sheet view but no parent with viewController specified. and the app closes
• When is selected and element from the list and is called closeCallback the same error appears but the app doesn’t crash, instead, the bottomsheet is not closed and the user haves to close doing a tap outside.
