updateShouldNotify method
Only notify when the breakpoints or the breakpoint changes. This helps a lot with performance, since we are only rebuilding widgets when the breakpoint changes, and not whenever the window's width changes.
Implementation
@override
bool updateShouldNotify(covariant ResponsiveBreakpointProviderScope oldWidget) {
return breakpoints != oldWidget.breakpoints || breakpoint != oldWidget.breakpoint;
}
