breakpointsLandscape property Null safety
A list of breakpoints that are active when the device is in landscape orientation.
In Flutter, the returned device orientation is not the real device orientation, but is calculated based on the screen width and height. This means that landscape only makes sense on devices that support orientation changes. By default, landscape breakpoints are only active when the ResponsiveTargetPlatform is Android, iOS, or Fuchsia. To enable landscape breakpoints on other platforms, pass a custom list of supported platforms to landscapePlatforms.
final List<ResponsiveBreakpoint>? breakpointsLandscape;
