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.

Properties
- willHandlePopInternally → bool
-
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
-
restorationScopeId
→ ValueListenable<
String?> -
The restoration scope ID to be used for the RestorationScope surrounding
this route. [...]
read-only, inherited
-
overlayEntries
→ List<
OverlayEntry> -
The overlay entries of this route. [...]
read-only, inherited
- 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. [...]
read-only, inherited
-
popped
→ Future<
T?> -
A future that completes when this route is popped off the navigator. [...]
read-only, inherited
- isCurrent → bool
-
Whether this route is the top-most route on the navigator. [...]
read-only, inherited
- isFirst → bool
-
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.

Methods
-
addLocalHistoryEntry(
LocalHistoryEntry entry) → void - Adds a local history entry to this route. [...]
-
removeLocalHistoryEntry(
LocalHistoryEntry entry) → void - Remove a local history entry from this route. [...]
-
willPop(
) → Future< RoutePopDisposition> -
Returns whether calling Navigator.maybePop when this Route is current
(isCurrent) should do anything. [...]
override
-
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 -

-
didAdd(

Called after install when the route is added to the navigator. [...]
@mustCallSuper, @protected, inherited
-
didReplace(
