The hash code for this object.
no setterinherited
hasListeners bool
Whether any listeners are currently registered.
no setterinherited
hasMessage bool
Returns the message status of the ViewModel
no setterinherited
initialised bool
no setterinherited
isBusy bool
Returns the busy status of the ViewModel
no setterinherited
modelError → dynamic
Returns the error status of the ViewModel
no setterinherited

Returns the message status of the ViewModel
no setterinherited
onModelReadyCalled bool
no setterinherited
reactiveServices List<ReactiveServiceMixin>
no setteroverride
reverse bool
Indicates whether we're going forward or backward in terms of the index we're changing. This is very helpful for the page transition directions.

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
isIndexSelected(int index) bool
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
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
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
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
setIndex(int value) → void
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
toString() String
A string representation of this object.
