How to set the child if it comes from onGenerateRoute ?

[postpasspost]

I do not have access to the child parameter from the builder because it comes from the onGenerateRoute: onGenerateRoute

I found this BouncingScrollWrapper.builder(context, widget)! It works for mobiles, tablets and laptops!

            builder: (context, widget) => ResponsiveWrapper.builder(
                BouncingScrollWrapper.builder(context, widget),
                maxWidth: 1200,
                minWidth: 480,
                defaultScale: true,
                breakpoints: [
                  ResponsiveBreakpoint.resize(480, name: MOBILE),
                  ResponsiveBreakpoint.autoScale(800, name: TABLET),
                  ResponsiveBreakpoint.resize(1000, name: DESKTOP, scaleFactor: 1.2),
                ],
              background: Container(color: Color(0xFFF5F5F5)),
            ),

I thought that UI looked too small on tablet simulator. Using scaleFactor allows to scale the UI for high resolution devices. I set it to 1.2 and everything seems to be well resized. What would be a good value for iPad simulator (is 1.0 good)?

The package works very well! Thanks!
