Great! I've always been using MediaQuery but that will return the screen size (in my case). But this video taught me how I can access each widget specifically using the key. Thanks a lot!

[@rutvikrana512]

You can use LayoutBuilder For That instead of using keys....

[@rydmike]

Thanks, this was very informative, I've been wondering how this can be done in Flutter. Really helpful to see this example!

[@ssiroma]

I was using very complicated and error prone ways of getting the size of an image, this works great.Thanks a lot.

[@jerinfrancis4509]

WidgetBinding.instance will be very useful. Thanks for sharing that with us !

[@crazy-man]

Thanks for this man , but is it possible to keep tracking the location of that widget , for example if a widget is inside a scrollable list , then keep track of where the widget's location is , because it will change based on the scroll
