Flickable (accessible in ScrollView through the flickableItem property) has a bottomMargin property which should be set to the bottom bar's height. 

I don't recall whether our Page is scrollable automatically or you have to explicitly place a ScrollView there. In the latter case I don't know how we could automatically ensure it works properly.
