FlameBiding class

This class never needs to be used.

It only exists here in order for BindingBase to setup Flutter services. TODO: this could possibly be private, verify if it'd work.

Mixed in types




defaultBinaryMessenger BinaryMessenger
The default instance of BinaryMessenger.
read-only, inherited
gestureArena GestureArenaManager
The gesture arenas used for disambiguating the meaning of sequences of pointer events.
final, inherited
hashCode → int
The hash code for this object.
read-only, inherited
locked → bool
Whether lockEvents is currently locking events.
@protected, read-only, inherited
pointerRouter PointerRouter
A router that routes all pointer events received from the engine.
final, inherited
pointerSignalResolver PointerSignalResolver
The resolver used for determining which widget handles a pointer signal event.
final, 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


cancelPointer(int pointer) → void
Dispatch a PointerCancelEvent for the given pointer soon.
createBinaryMessenger() BinaryMessenger
Creates a default BinaryMessenger instance that can be used for sending platform messages.
@protected, inherited
dispatchEvent(PointerEvent event, HitTestResult hitTestResult) → void
Dispatch an event to a hit test result's path.
evict(String asset) → void
Called in response to the ext.flutter.evict service extension.
@mustCallSuper, @protected, inherited
handleEvent(PointerEvent event, HitTestEntry entry) → void
Override this method to receive events.
handleSystemMessage(Object systemMessage) → Future<void>
Handler called for messages received on the SystemChannels.system message channel.
@mustCallSuper, @protected, inherited
hitTest(HitTestResult result, Offset position) → void
Determine which HitTestTarget objects are located at a given position.
initInstances() → void
The initialization method. Subclasses override this method to hook into the platform and otherwise configure their services. Subclasses must call "super.initInstances()".
initLicenses() → void
Adds relevant licenses to the LicenseRegistry.
@mustCallSuper, @protected, inherited
initServiceExtensions() → void
Called when the binding is initialized, to register service extensions.
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.
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.
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.
unlocked() → void
Called by lockEvents when events get unlocked.


operator ==(dynamic other) → bool
The equality operator.
