Define go_responsive.dart:
import 'package:flutter/widgets.dart';
import 'package:go_responsive/go_responsive.dart';
import 'package:go_responsive_annotation/go_responsive_annotation.dart';

part 'go_responsive.g.dart';

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


return GoResponsiveBuilder from MaterialApp builder function and set breakpoint to already defined breakpoints list from go_responsive.dart:
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,
child: child,
);
},
);
}
}
copied to clipboard


now run dart run build_runner build in console which will generate go_responsive.g.dart


then import go_responsive.dart can be use context.goResponsiveValue:
class Home extends StatelessWidget {
const Home({super.key});

@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
color: context.goResponsiveValue(
compact: Colors.red,
medium: Colors.green,
expanded: Colors.blue,
defaultValue: Colors.black,
),
),
);
}
}
copied to clipboard


use or GoResponsiveWidget
class Home2 extends StatelessWidget {
const Home2({super.key});

@override
Widget build(BuildContext context) {
return Scaffold(
body: GoResponsiveWidget(
compact: Container(color: Colors.red),
medium: Container(color: Colors.green),
expanded: Container(color: Colors.blue),
defaultWidget: Container(color: Colors.black),
),
);
}
}
copied to clipboard


or use context.is{breakpoint_name} with if else
class Home3 extends StatelessWidget {
const Home3({super.key});

@override
Widget build(BuildContext context) {
var color = Colors.black;

if (context.isCompact) {
color = Colors.red;
}

if (context.isMedium) {
color = Colors.green;
}

if (context.isExpanded) {
color = Colors.blue;
}

return Scaffold(
body: Container(color: color),
);
}
}
copied to clipboard


or use context.goResponsiveData and GoResponsiveBreakpoints.{breakpoint_name}
combination for custom conditions
class Home4 extends StatelessWidget {
const Home4({super.key});

@override
Widget build(BuildContext context) {
var color = Colors.black;

if (context.goResponsiveData
.smallerOrEqualTo(GoResponsiveBreakpoints.compact)) {
color = Colors.red;
}

if (context.goResponsiveData.between(
GoResponsiveBreakpoints.compact,
GoResponsiveBreakpoints.expanded,
)) {
color = Colors.green;
}

if (context.goResponsiveData.between(
GoResponsiveBreakpoints.medium,
GoResponsiveBreakpoints.expanded,
)) {
color = Colors.blue;
}

return Scaffold(
body: Container(color: color),
);
}
}
