FluttermojiController class

Brains of the Fluttermoji package

Built using the getX architecture to allow the two widgets to communicate with each other

Exposes certain static functions for use by the developer

  • Object
  • GetLifeCycle
  • DisposableInterface
  • GetxController
  • FluttermojiController




fluttermoji ↔ RxString
getter/setter pair
hashCode int
The hash code for this object.
no setterinherited
hasListeners bool
no setterinherited
initialized bool
Checks whether the controller has already been initialized.
no setterinherited
isClosed bool
Checks whether the controller has already been closed.
no setterinherited
listeners int
no setterinherited
onDelete → InternalFinalCallback<void>
Internal callback that starts the cycle of this controller.
onStart → InternalFinalCallback<void>
Called at the exact moment the widget is allocated in memory. It uses an internal "callable" type, to avoid any @overrides in subclases. This method should be internal and is required to define the lifetime cycle of the subclass.
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
selectedIndexes Map<String?, dynamic>
getter/setter pair
selectedOptions Map<String?, dynamic>
Stores the option selected by the user for each attribute where the key represents the Attribute and the value represents the index of the selected option.
getter/setter pair


$configureLifeCycle() → void
addListener(GetStateUpdate listener) → Disposer
Register a closure to be called when the object notifies its listeners.
addListenerId(Object? key, GetStateUpdate listener) → Disposer
dispose() → void
disposeId(Object id) → void
To dispose an id from future updates(), this ids are registered by GetBuilder() or similar, so is a way to unlink the state change with the Widget from the Controller.
getComponentSVG(String? attributeKey, int? attributeValueIndex) String
Generates compnonent SVG string for an individual component to display as a preview
getComponentTitle(String attributeKey, int attriibuteValueIndex) String?
getFluttermojiFromOptions() String
Generates a String fluttermoji from selectedOptions pref
getFluttermojiOptions() Future<Map<String?, int>>
init() → void
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
notifyChildrens() → void
onClose() → void
Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
onInit() → void
Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
onReady() → void
Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
refresh() → void
refreshGroup(Object id) → void
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
removeListenerId(Object id, VoidCallback listener) → void
restoreState() → void
Restore controller state with the latest SAVED version of fluttermoji and selectedOptions
setFluttermoji({String fluttermojiNew = ''}) Future<void>
Accepts a String fluttermoji
toString() String
A string representation of this object.
update([List<Object>? ids, bool condition = true]) → void
Rebuilds GetBuilder each time you call update(); Can take a List of ids, that will only update the matching GetBuilder( id: ), ids can be reused among GetBuilders like group tags. The update will only notify the Widgets, if condition is true.
updatePreview({String fluttermojiNew = ''}) → void
Adds fluttermoji new string to fluttermoji in GetX Controller


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