Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
busy(Object? object) → bool: Returns the busy status for an object if it exists. Returns false if not present
inherited
clearErrors() → void: Clears all the errors
inherited
clearMessages() → void: 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).
inherited
error(Object object) → dynamic: inherited
hasErrorForKey(Object key) → bool: Returns a boolean that indicates if the ViewModel has an error for the key
inherited
hasMessageForKey(Object key) → bool: Returns a boolean that indicates if the ViewModel has an message for the key
inherited
init() → void: initialise the animation controller
message(Object object) → String?: Returns the message for an object if it exists. Returns null if not present
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
onFutureError(dynamic error, Object? key) → void: Function that is called when a future throws an error
inherited
popRouteName(BuildContext context) → Future<bool>: same for other apps if the user is already zooming on the image and he press the system back button the screen will not close but the image will be resized to the original size a
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
returnToPreviousPage(BuildContext context) → Future<bool>
runBusyFuture<T>(Future<T> busyFuture, {Object? busyObject, bool throwException = false}) → Future<T>: Sets the ViewModel to busy, runs the future and then sets it to not busy when complete.
inherited
runErrorFuture<T>(Future<T> future, {Object? key, bool throwException = false}) → Future<T>: inherited
setBoxFit(double scale) → void: this method is called to update Boxfit value
setBusy(bool value) → void: Marks the ViewModel as busy and calls notify listeners
inherited
setBusyForObject(Object? object, bool value) → void: Sets the busy state for the object equal to the value passed in and notifies Listeners If you're using a primitive type the value SHOULD NOT BE CHANGED, since Hashcode uses == value
inherited
setError(dynamic error) → void: Sets the error for the ViewModel
inherited
setErrorForObject(Object object, dynamic value) → void: Sets the error state for the object equal to the value passed in and notifies Listeners If you're using a primitive type the value SHOULD NOT BE CHANGED, since Hashcode uses == value
inherited
setInitialised(bool value) → void: Sets the initialised value for the ViewModel to true. This is called after the first initialise special ViewModel call
inherited
setMessage(String? message) → void: Sets the message for the ViewModel
inherited
setMessageForObject(Object object, String? value) → void: Sets the message for the object equal to the value passed in and notifies Listeners If you're using a primitive type the value SHOULD NOT BE CHANGED, since Hashcode uses == value
inherited
setOnModelReadyCalled(bool value) → void: Sets the onModelReadyCalled value to true. This is called after this first onModelReady call
inherited
setupStream<T>(Stream<T> stream, {dynamic onData, dynamic onSubscribed, dynamic onError, dynamic onCancel, dynamic transformData}) → StreamData: inherited
skeletonData<T>({required T? realData, required T busyData, Object? busyKey}) → T: returns real data passed if neither the model is busy nor the object passed is busy
inherited
tapLocation(TapDownDetails detail) → void: this methode is called to get position where the user has tapped it take TapDownDetails as a parameter
toString() → String: A string representation of this object.
inherited
userScaleState() → void: this methode is used to indicate if the user is currently zooming on the image
userStartZooming() → void: when this methode is called if the user is not zooming in it zoom on the position where the user has tapped on else it show the image to the original size also it update scaling state

Operators

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