includeRouteSemantics property
Whether this route introduces a route scope in the semantics tree.
Defaults to true. When true, screen readers can treat pushes and pops of this route as navigation to a new screen and announce the change to users.
Set this to false for routes that update only part of the screen, such as tab or shell content in a nested navigator. This prevents screen readers from treating the route as a new screen.
Implementation
final bool includeRouteSemantics;
