Static Properties

entryTimestamps → Map<String, DateTime>
Entry time per route name. If the same route is on the stack more than once, the most recent entry wins.
no setter
instance → RouteObserver<PageRoute>
The singleton observer instance to pass to MaterialApp.navigatorObservers.
no setter
routeArguments → Map<String, dynamic>
Route arguments by route name, from the most recent push/replace of that name.
final
routeHistory → List<String>
A running log of push/pop/replace events, newest-appended, capped at 1000 entries.
no setter
routeStack → List<String>
Names of routes currently on the navigator stack, oldest first. A name appears once per time it's on the stack, so A → B → A lists [A, B, A].
no setter
routeVersion → ValueNotifier<int>
Bumped on every navigation event and clear, so the Routes tab can rebuild.
final

Static Methods

clear() → void
Clears the recorded history. Routes still on the navigator stack are left alone — they are live state, not history, and dropping them would break duration tracking for screens the user still has open.
init() → void
Logs a one-time initialization notice. Called once by FlutterDevToolkit.init.
