VitalsManager class
Central controller that manages all performance trackers and produces periodic PerformanceReport snapshots.
Extends ChangeNotifier so widgets (like VitalsOverlay) can listen for report updates.
Quick start:
final vitals = VitalsManager();
vitals.start();

- hasListeners → bool
-
Whether any listeners are currently registered.

Latest aggregated performance report.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- startupTracker → StartupTracker
-
Individual trackers — exposed so callers can interact directly
(e.g.
vitals.networkTracker.trackRequest(...)).final - updateInterval → Duration

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
refresh(
) → Future< void> - Force a report update.
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
start(
) → void - Start all trackers and begin periodic report updates.
-
stop(
) → void - Stop all trackers and periodic updates.
-
stopStartup(
) → void - Stop the startup timer. Call this after the first frame renders.
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Properties
- instance → VitalsManager
-
