I am creating a message page, where an admin can send messages to the users on the app.
I use a Container, with a Column with a Row and an AnimatedContainer as children, the AnimatedContainer also holds a Column with two Listviews and a TextField.
The Row holds an Icons.add button, whenever the button is pressed, _isExpanded =! _isExpanded. When _isExpanded, the AnimatedContainer height is set to 400, when !_isExpanded, the height is 0. My weakness in flutter is working with spacing, boundries etc. Whenever I expand my AnimatedContainer, I get a bottomOverflow error, which isn't surprising because my Column inside the Animated container (and it's children) have a fixed width. I tried wrapping a lot of widgets with Expanded, but I can't seem to find the right combination. The error keeps appearing. Anyone who is able to help me resolve this?

_isExpanded = !_isExpanded;
