ResponsiveInit class
Top-level initializer that registers breakpoints and wires up
flutter_screenutil.
Place ResponsiveInit above your MaterialApp/CupertinoApp. It:
- registers your ordered
BreakpointswithResponsiveUtils - detects the active device type by current screen width
- looks up the exact active breakpoint via
breakpointForWidth - re-configures
ScreenUtilInitwhenever the device type changes so scaling anddesignSizealways match the active breakpoint
