Sizing elements to percentage of screen width/height

Question

Is there a simple (non-LayoutBuilder) way to size an element relative to screen size (width/height)? For example: how do I set the width of a CardView to be 65% of the scree

Answer 1

you can use MediaQuery with the current context of your widget and get width or height like this double width = MediaQuery.of(context).size.width double height = MediaQuery.of(context).size.height after that, you can multiply it with the percentage you want
