Modal Bottom Sheet double import

[SashaKrstev]

Modal Bottom sheet is being imported from both the Material library and the modal_bottom_sheet package, resulting with build error in 'widget/modal_sheet_presentation.dart'

Fixed by updating the modal bottom sheet package and hiding the class from the material library
