MediaQuery.of() Flutter

Question

i am searching a way for sizing a element in flutter with the dimensions of the parent widget. How can I do?

I tried with MediaQuery.of(WidgetParent) but this not work.

Thanks

Answer 1

If you want to size the current widget with respect to the parent widget's dimensions, check this Widget FractionallySizedBox

Answer 2

The MediaQuery.of(context) returns the device's screen size, not the parent widget.

You can get the size of the parent widget by using the LayoutBuilder.
