QUESTION
I'm new to Flutter and I've been stuck here for a while now. I am trying to make a main screen in Flutter for web, but I keep getting this error every time I try to apply the expanded property to the listview widget.
This is the code, the error, and what I'm trying to get:
[What I'm trying to do]: ...ANSWER
Answered 2020-Mar-27 at 10:29The error occurs because you are trying to expand without constrains. Expanded Widget
is used with a parent with dimension constrains. Since you are using it directly as one of the children in a column it can't infer which dismission to take.
By default Expanded
expand to fill dimension of the parent so you have to provide a parent like a container or padding or sizeBoxed
Edit:
You will also need some flex widgets ( Flexible
) to achieve the layout.
