The problem is that whenever I open the model bottom sheet and when the keyboard appears on pressing a text field the chart widget behind the ModalBottomSheet overflows and this only happens when I switch to landscape mode.

Reset to default 0When the keyboard appears, the Row that contains your Chart does not have a sufficient height, and a layout error occurs in your Chart. We don't know what the chart looks like, but one of its children requires more height than available with the keyboard present in landscape mode.
In such a case, a possible solution can be to wrap your Scaffold body in a SingleChildScrollView, so that when the space becomes too small, it will automatically scroll. But again, it really depends on what's actually going on in your Chart widget.
