Flutter - how to get the height and width of the AspectRatio widget?-CodePudding

AspectRatio(
        aspectRatio: 1,
        child: Container(
          color: Colors.blue,
        ),
      ),

I am trying to hand over AspectRatio's width and height to its child Container. I am trying to use this info to create the responsive Text widget. Is there any way that I can get the height and width of the AspectRatio?

CodePudding user response：

You can use LayoutBuilder to get the height and width of the AspectRatio. It is returned in terms of maxWidth and maxHeight of constraint.

AspectRatio(
        aspectRatio: 1,
        child: LayoutBuilder(
               builder(context, constraints){

                  debugPrint(constraints.toString());
                  return Container(
                     color: Colors.blue,
                  );
               }
          ),
      ),
