• Define breakepoints as top level list of GoResponsiveBreakpoint and annotate it with @GoResponsive():

  @GoResponsive()
  const breakpoints = [
    GoResponsiveBreakpoint(size: 600, name: 'compact'),
    GoResponsiveBreakpoint(size: 840, name: 'medium'),
    GoResponsiveBreakpoint(size: double.maxFinite, name: 'expanded'),
  ];
  

• return GoResponsiveBuilder from MaterialApp builder function and set breakpoint to already defined breakpoints list:

  class App extends StatelessWidget {
    const App({super.key});
  
    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        home: const Home(),
        builder: (context, child) {
          return GoResponsiveBuilder(
            breakpoints: breakpoints,

          );
        },
      );
    }
  }
  

• now run dart run build_runner build in console which will generate <file_name>.name.go_responsive.dart

          ),
          expanded: Container(
            color: Colors.blue,
          ),
          defaultWidget: Container(
            color: Colors.black,
          ),
        ),
      );
