PaintingBinding mixin - painting library

Constructors

PaintingBinding()

Properties

imageCache → ImageCache: The singleton that implements the Flutter framework's image cache. [...]
read-only
hashCode → int: The hash code for this object. [...]
read-only, inherited
locked → bool: Whether lockEvents is currently locking events. [...]
@protected, read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited
window → Window: The window to which this binding is bound. [...]
read-only, inherited

Methods

createImageCache() → ImageCache: Creates the ImageCache singleton (accessible via imageCache). [...]
@protected
evict(String asset) → void: Called in response to the ext.flutter.evict service extension. [...]
override
initInstances() → void: The initialization method. Subclasses override this method to hook into the platform and otherwise configure their services. Subclasses must call "super.initInstances()". [...]
override
instantiateImageCodec(Uint8List list) → Future<Codec>: Calls through to dart:ui with decodedCacheRatioCap from ImageCache.
initLicenses() → void: Adds relevant licenses to the LicenseRegistry. [...]
@mustCallSuper, @protected, inherited
initServiceExtensions() → void: Called when the binding is initialized, to register service extensions. [...]
inherited
lockEvents(Future<void> callback()) → Future<void>: Locks the dispatching of asynchronous events and callbacks until the callback's future completes. [...]
@protected, inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
performReassemble() → Future<void>: This method is called by reassembleApplication to actually cause the application to reassemble, e.g. after a hot reload. [...]
@mustCallSuper, @protected, inherited
postEvent(String eventKind, Map<String, dynamic> eventData) → void: All events dispatched by a BindingBase use this method instead of calling developer.postEvent directly so that tests for BindingBase can track which events were dispatched by overriding this method.
@protected, inherited
reassembleApplication() → Future<void>: Cause the entire application to redraw, e.g. after a hot reload. [...]
inherited
registerBoolServiceExtension({String name, AsyncValueGetter<bool> getter, AsyncValueSetter<bool> setter }) → void: Registers a service extension method with the given name (full name "ext.flutter.name"), which takes a single argument "enabled" which can have the value "true" or the value "false" or can be omitted to read the current value. (Any value other than "true" is considered equivalent to "false". Other arguments are ignored.) [...]
@protected, inherited
registerNumericServiceExtension({String name, AsyncValueGetter<double> getter, AsyncValueSetter<double> setter }) → void: Registers a service extension method with the given name (full name "ext.flutter.name"), which takes a single argument with the same name as the method which, if present, must have a value that can be parsed by double.parse, and can be omitted to read the current value. (Other arguments are ignored.) [...]
@protected, inherited
registerServiceExtension({String name, ServiceExtensionCallback callback }) → void: Registers a service extension method with the given name (full name "ext.flutter.name"). [...]
@protected, inherited
registerSignalServiceExtension({String name, AsyncCallback callback }) → void: Registers a service extension method with the given name (full name "ext.flutter.name"), which takes no arguments and returns no value. [...]
@protected, inherited
registerStringServiceExtension({String name, AsyncValueGetter<String> getter, AsyncValueSetter<String> setter }) → void: Registers a service extension method with the given name (full name "ext.flutter.name"), which optionally takes a single argument with the name "value". If the argument is omitted, the value is to be read, otherwise it is to be set. Returns the current value. [...]
@protected, inherited
toString() → String: Returns a string representation of this object.
inherited
unlocked() → void: Called by lockEvents when events get unlocked. [...]
@mustCallSuper, @protected, inherited

Operators

operator ==(dynamic other) → bool: The equality operator. [...]
inherited

Static Properties

instance → PaintingBinding: The current PaintingBinding, if one has been created.
read-only
shaderWarmUp ↔ ShaderWarmUp: ShaderWarmUp to be executed during initInstances. [...]
