I've spent hours attempting to make an AppBar show a title having a particular height. From what I have read on SO etc., it can be done, however I cannot achieve it and I have spent many hours attempting to. I need to make the "title:" and "actions:" have a height of about 70 or thereabouts.
From what I can determine from various tests that I have performed, when the size of the AppBar exceeds a certain size, any excess size automatically goes to the "bottom:" which in the case of my app is the TabBar.
I tested a PreferredSize for that AppBar in another test where there was no "bottom:" and no TabBar, and the space allocated to the AppBar in the program was sufficient to display the large title, but only part of the title having a large font showed. The remainder of the space that was allocated to the AppBar in that case was just blank and showed below the display of the title.
In another program that I have written, I have set the AppBar height to 35 and that works without a problem. So it appears that setting the AppBar height to a low value works for the title, but setting it to a large value does not.
I would appreciate a solution to this problem because the need for this is integral to my program and I have spent a lot of time attempting to solve the problem.
This problem appears to be solved by AppBar "flexibleSpace:".
