The ExpansionTile inherits from the ListTile, which has a fixed height. There are no input args for tile height.
I've tried wrapping the ExpansionTile in a Container widget with a hardcoded height, but that causes the children widgets to only take up the space within the hardcoded height. Currently, because the contents in the title widget are large, I have a "Column overflowed by 23 pixels" message.
Is there any way to change an Expansion Tile's height? Or is there another Widget I could use that has the expansion/accordion feature?
I would probably copy ExpansionTile and make your own version. Sizing ListTile is easy with a Container or SizedBox, but ExpansionTile is a material widget and it doesn't look like it was built with your use case in mind.
