  Widget buildMobilePortraitLayout(
      BuildContext context, DeviceUtils deviceUtils) {
    return Scaffold(
        appBar: AppBar(),
        body: Center(
            child: Container(),
        )

class ProgressBar extends AppWidgetState {
  const ProgressBar({Key? key}) : super(key: key);


  @override
  Widget buildMobilePortraitLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Center(
      child: Platform.isIOS
          ? const CupertinoActivityIndicator(
              radius: 50,
            )
          : const SizedBox(
              width: 50,
              height: 50,
              child: CircularProgressIndicator(),
            ),
    );
  }
}

Orientation

If you want to support both portrait and landscape orientations

 @override
 Widget buildMobilePortraitLayout(BuildContext context, DeviceUtils deviceUtils}

 @override
 Widget buildMobileLandscapeLayout(BuildContext context, DeviceUtils deviceUtils}

ScreenType

If you want the same layout to look different in desktop, tablet and mobile, use the deviceUtils.screenType method:

deviceUtils.screenType == DeviceScreenType.tablet
  ? Container(   // Widget for Tablet
      width: 200,
      height: 25,
   )
  : deviceUtils.screenType == DeviceScreenType.desktop 
  ? Container(   // Widget for Mobile
      width: 400,
      height: 50,
   ) : Container(   // Widget for Mobile
      width: 100,
      height: 12.5,
   )

BuildLayout

If you want the same layout to look different in tablet and mobile, override buildMobilePortraitLayout, buildTabletPortraitLayout, buildDesktopPortraitLayout method:

class ProgressBar extends AppWidgetState {
  const ProgressBar({Key? key}) : super(key: key);


  @override
  Widget buildMobilePortraitLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Container(
    );
  }

  @override
  Widget buildTabletPortraitLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Center(
    );
  }

  @override
  Widget buildDesktopPortraitLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Center(
    );
  }

  @override
  Widget buildMobileLandscapeLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Center(
    );
  }

  @override
  Widget buildTabletLandscapeLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Center(
    );
  }

  @override
  Widget buildDesktopLandscapeLayout(
      BuildContext context, DeviceUtils deviceUtils) {
      return Center(
    );
  }
}
