CropController class - controller library

Constructors

CropController(Uint8List image)

Properties

aspect → double: Returns the aspect ratio of image.
no setter
crop → Rx<Rect>: Crop rectangle coordinates for image.
final
dimensions → Rx<Size>: Size of the image.
final
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: no setterinherited
image → Uint8List: Uint8List of the image to crop.
final
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.
finalinherited
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.
finalinherited
real → Rect: Returns the crop rectangle of image in pixels.
no setter
rotation → Rx<CropRotation>: Current image rotation.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
size → Size: Returns the Size of the image.
no setter
svg ↔ PictureInfo?: PictureInfo of the image being an SVG.

Methods

$configureLifeCycle() → void: inherited
addListener(GetStateUpdate listener) → Disposer: Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, GetStateUpdate listener) → Disposer: inherited
dispose() → void: inherited
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.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyChildrens() → void: inherited
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.
inherited
onInit() → void: Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
override
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.
inherited
refresh() → void: inherited
refreshGroup(Object id) → void: inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void: inherited
rotateLeft() → void: Rotates image 90 degrees left.
rotateRight() → void: Rotates image 90 degrees right.
toString() → String: A string representation of this object.
inherited
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.

Operators

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