LocalHistoryRoute<T> mixin
Null safety
A mixin used by routes to handle back navigations internally by popping a list.
When a Navigator is instructed to pop, the current route is given an
opportunity to handle the pop internally. A LocalHistoryRoute handles the
pop internally if its list of local history entries is non-empty. Rather
than being removed as the current route, the most recent LocalHistoryEntry
is removed from the list and its LocalHistoryEntry.onRemove is called.

-
Whether calling didPop would return false.
read-only, override
-
The navigator that the route is in, if any.
read-only, inherited
- settings → RouteSettings
-
The settings for this route.
read-only, inherited

popped
→ Future<
T?> -
A future that completes when this route is popped off the navigator.

Whether this route is the top-most route on the navigator.
read-only, inherited

-
Whether this route is the bottom-most active route on the navigator.
read-only, inherited
- hasActiveRouteBelow → bool
-
Whether there is at least one active route underneath this route.
@protected, read-only, inherited

Methods
-
addLocalHistoryEntry(
LocalHistoryEntry entry) → void - Adds a local history entry to this route.
-
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.
@mustCallSuper, @protected, inherited
-
changedInternalState(
) → void -
Called whenever the internal state of the route has changed.
@mustCallSuper, @protected, inherited
-
didAdd(
) → void -
Called after install when the route is added to the navigator.
@mustCallSuper, @protected, inherited
-
didChangeNext(
Route? nextRoute) → void -
This route's next route has changed to the given new route.
@mustCallSuper, @protected, inherited
-
didChangePrevious(
Route? previousRoute) → void -
This route's previous route has changed to the given new route.
@mustCallSuper, @protected, inherited
-
didComplete(
T? result) → void -
The route was popped or is otherwise being removed somewhat gracefully.
@mustCallSuper, @protected, 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.
@mustCallSuper, @protected, inherited
-
didPush(
) → TickerFuture -
Called after install when the route is pushed onto the navigator.
@mustCallSuper, @protected, inherited
-
didReplace(
Route? oldRoute) → void -
Called after install when the route replaced another in the navigator.
@mustCallSuper, @protected, inherited
-
dispose(
) → void -
Discards any resources used by the object.
@mustCallSuper, @protected, inherited
-
install(
) → void -
Called when the route is inserted into the navigator.
@mustCallSuper, @protected, inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
removeLocalHistoryEntry(
LocalHistoryEntry entry) → void - Remove a local history entry from this route.
-
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.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
