Bottom tab navigator hide part of my screen

I’m using a bottom tab navigator with a page with a dataviewer list.
The Tab navigator hide the bottom part of my list.
So I thought about resize my whole page to a certain percentage, but it’s not clear how to set the height of the tab bar or if there is a default dimension of it (in this case,which is the dimension?)
An example of what I would do is to have a tab navigator with height 10% and the whole page in a column with height 90%
Could it be a solution or there is a better way to do it?
