popRoute method
Called by the Router when the Router.backButtonDispatcher reports that the operating system is requesting that the current route be popped.
The method should return a boolean Future to indicate whether this delegate handles the request. Returning false will cause the entire app to be popped.
Consider using a SynchronousFuture if the result can be computed synchronously, so that the Router does not need to wait for the next microtask to schedule a build.
Implementation
@override
Future<bool> popRoute({
Object? result,
PopMode popMode = PopMode.Page,
}) async {
//Returning false will cause the entire app to be popped.
final wasPopup = await handlePopupRoutes(result: result);
if (wasPopup) return true;
final popped = await _pop(popMode);
refresh();
if (popped != null) {
//emulate the old pop with result
return true;
}
return false;
}
