How to make Flutter Responsive app for all platform

Which is best dependency or method to make flutter responsive to all platforms.

I tried using ScreenUtil and Media Query but don’t exactly know how to do it

>Solution :

Hi Ferox use below Class to make your UI responsive

class Responsive extends StatelessWidget {
  final Widget mobile;
  final Widget tablet;
  final Widget desktop;

const Responsive({
 Key? key,
required this.mobile,
required this.tablet,
required this.desktop,
}) : super(key: key);


static bool isMobile(BuildContext context) =>
  MediaQuery.of(context).size.width < 850;

static bool isTablet(BuildContext context) =>
  MediaQuery.of(context).size.width < 1100 &&
  MediaQuery.of(context).size.width >= 850;

static bool isDesktop(BuildContext context) =>
  MediaQuery.of(context).size.width >= 1100;

@override
Widget build(BuildContext context) {
final Size size = MediaQuery.of(context).size;

if (size.width >= 1100) {
  return desktop;
} else if (size.width >= 850) {
  return tablet;
} else {
  return mobile;
}
}
}

and use it like

   if (Responsive.isDesktop(context))
            Container(),//your UI
