didPop method
- T? result
A request was made to pop this route. If the route can handle it
internally (e.g. because it has its own stack of internal state) then
return false, otherwise return true (by returning the value of calling
super.didPop). Returning false will prevent the default behavior of
NavigatorState.pop.
When this function returns true, the navigator removes this route from the history but does not yet call dispose. Instead, it is the route's responsibility to call NavigatorState.finalizeRoute, which will in turn call dispose on the route. This sequence lets the route perform an exit animation (or some other visual effect) after being popped but prior to being disposed.
This method should call didComplete to resolve the popped future (and this is all that the default implementation does); routes should not wait for their exit animation to complete before doing so.
See popped, didComplete, and currentResult for a discussion of the
result argument.
