Important!

Since version 0.1.0 the ResponsiveSettings class is no longer used to manage change points. Instead use ScreenChangePoints, check example for more details.

Add your own settings

Manage global the responsive screen change points with ResponsiveSettings class.

void main() {
  // Global Settings
  ResponsiveSettings.instance.setCustomSettings(
    screenChangePoints: const ScreenChangePoints(
      desktopChangePoint: 1150.0,
      tabletChangePoint: 625.0,
      watchChangePoint: 250.0,
    ),
  );
  runApp(const MyApp());
}

Use the responsive widget

The responsive widget allows you to have different layouts for each device.

const ResponsiveWidget(  
  // If don't set the global values will be applied, if do not exist global values,
  // the default values will be applied.
  screenChangePoints: ScreenChangePoints(),
  desktop: Scaffold(
    body: Center(
      child: Text(
        'Desktop screen',
        style: TextStyle(
          color: Colors.black,
          fontSize: 25.0,
        ),
      ),
    ),
  ),
  phone: Scaffold(
    body: Center(
      child: Text(
        'Phone screen',
        style: TextStyle(
          color: Colors.amber,
          fontSize: 25.0,
        ),
      ),
    ),
  ),
  tablet: Scaffold(
    body: Center(
      child: Text(
        'Tablet screen',
        style: TextStyle(
          color: Colors.greenAccent,
          fontSize: 25.0,
        ),
      ),
    ),
  ),
  watch: Scaffold(
    body: Center(
      child: Text(
        'Watch screen',
        style: TextStyle(
          color: Colors.blueAccent,
          fontSize: 25.0,
        ),
      ),
    ),
  ),
);

Use only responsive app bar

The responsive app bar allows to adapt the top tool bar to all screens.

const Scaffold(
  appBar: ResponsiveAppBar(
    // If don't set the global values will be applied, if do not exist global values,
    // the default values will be applied.
    screenChangePoints: ScreenChangePoints(),
    title: Text('Responsive app bar'),
    actions: [
      AppBarAction(
        Center(child: Text('About')),
      ),
      AppBarAction(
        SizedBox(width: 16.0),
        showInAllScreens: true,
      ),
      AppBarAction(
        Icon(Icons.brightness_auto_outlined),
        showInAllScreens: true,
      ),
      AppBarAction(
        SizedBox(width: 16.0),
        showInAllScreens: true,
      ),
    ],
  ),
);
