}) {
  return LayoutBuilder(
    builder: (context, constraints) {
      var maxHeight = constraints.maxHeight;
      return ScreenUtilInit(
        designSize: Size(
          designWidth.toDouble(),
          maxHeight > 0 ? maxHeight : designHeight.toDouble(),
        ),
        child: child,
      );
