Properties
- currentResult → T?
-
When this route is popped (see Navigator.pop) if the result isn't
specified or if it's null, this value will be used instead.
no setterinherited
- finishedWhenPopped → bool
-
Controls whether didPop calls NavigatorState.finalizeRoute.
no setter
- hasActiveRouteBelow → bool
-
Whether there is at least one active route underneath this route.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isActive → bool
-
Whether this route is on the navigator.
no setterinherited
- isCurrent → bool
-
Whether this route is the top-most route on the navigator.
no setterinherited

-
Whether this route is the bottom-most active route on the navigator.
no setterinherited
-
The navigator that the route is in, if any.
no setterinherited
-
overlayEntries
→ List<
OverlayEntry> -
The overlay entries of this route.
no setteroverride
- popDisposition → RoutePopDisposition
-
Returns whether calling Navigator.maybePop when this Route is current
(isCurrent) should do anything.
no setterinherited
-
popped
→ Future<
T?> -
A future that completes when this route is popped off the navigator.
no setterinherited
- requestFocus → bool
-
When the route state is updated, request focus if the current route is at the top.
no setterinherited
-
restorationScopeId
→ ValueListenable<
String?> -
The restoration scope ID to be used for the RestorationScope surrounding
this route.

Methods
-
changedExternalState(
) → void -
Called whenever the Navigator has updated in some manner that might
affect routes, to indicate that the route may wish to rebuild as well.
inherited
-
changedInternalState(
) → void -
Called whenever the internal state of the route has changed.
inherited
-
createOverlayEntries(
) → Iterable< OverlayEntry> - Subclasses should override this getter to return the builders for the overlay.
-
didAdd(
) → void -
Called after install when the route is added to the navigator.
inherited
-
didChangeNext(
Route? nextRoute) → void -
This route's next route has changed to the given new route.
inherited
-
didChangePrevious(
Route? previousRoute) → void -
This route's previous route has changed to the given new route.
inherited
-
didComplete(
T? result) → void -
The route was popped or is otherwise being removed somewhat gracefully.
inherited
-
didPop(
T? result) → bool -
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.override -
didPopNext(
Route nextRoute) → void -
The given route, which was above this one, has been popped off the
navigator.
inherited
-
didPush(
) → TickerFuture -
Called after install when the route is pushed onto the navigator.
inherited
-
didReplace(
Route? oldRoute) → void -
Called after install when the route replaced another in the navigator.
inherited
-
dispose(
) → void -
Discards any resources used by the object.
override
-
install(
) → void -
Called when the route is inserted into the navigator.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onPopInvoked(
bool didPop) → void -
Called after a route pop was handled.
inherited
-
onPopInvokedWithResult(
bool didPop, T? result) → void -
Called after a route pop was handled.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
willPop(
) → Future< RoutePopDisposition> -
Returns whether calling Navigator.maybePop when this Route is current
(isCurrent) should do anything.

Operators

operator ==(
Object other) → bool -
The equality operator.
