A concrete binding for applications that use the Rendering framework directly. This is the glue that binds the framework to the Flutter engine.

You would only use this binding if you are writing to the rendering layer directly. If you are writing to a higher-level library, such as the Flutter Widgets library, then you would use that layer's binding.

See also BindingBase.

Methods

addFrameCallback(FrameCallback callback, { bool rescheduling: false }) int

Adds a transient frame callback.

inherited
addPersistentFrameCallback(FrameCallback callback) → void

Adds a persistent frame callback.

inherited
addPostFrameCallback(FrameCallback callback) → void

Schedule a callback for the end of this frame.

inherited
beginFrame() → void

Pump the rendering pipeline to generate a frame.

inherited
cancelFrameCallbackWithId(int id) → void

Cancels the transient frame callback with the given id.

inherited
cancelPointer(int pointer) → void

Dispatch a PointerCancelEvent for the given pointer soon.

inherited
createViewConfiguration() ViewConfiguration

Returns a ViewConfiguration configured for the RenderView based on the current environment.

inherited
debugAssertNoTransientCallbacks(String reason) bool

Asserts that there are no registered transient callbacks; if there are, prints their locations and throws an exception.

inherited
dispatchEvent(PointerEvent event, HitTestResult result) → void

Dispatch an event to a hit test result's path.

inherited
ensureVisualUpdate() → void

Schedules a new frame using scheduleFrame if this object is not currently producing a frame.

inherited
handleBeginFrame(Duration rawTimeStamp) → void

Called by the engine to produce a new frame.

inherited
handleEvent(PointerEvent event, HitTestEntry entry) → void

Override this method to receive events.

inherited
handleEventLoopCallback() → void

Called by the system when there is time to run tasks.

inherited
handleMetricsChanged() → void

Called when the system metrics change.

inherited
hitTest(HitTestResult result, Point position) → void

Check whether the given position hits this object.

inherited
initInstances() → void

The initialization method. Subclasses override this method to hook into the platform and otherwise configure their services. Subclasses must call "super.initInstances()".

inherited
initRenderView() → void

Creates a RenderView object to be the root of the RenderObject rendering tree, and initializes it so that it will be rendered when the engine is next ready to display a frame.

inherited
initServiceExtensions() → void

Called when the binding is initialized, to register service extensions.

inherited
noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
reassembleApplication() → void

Called when the ext.flutter.reassemble signal is sent by development tools.

inherited
registerBoolServiceExtension({String name, ValueGetter<bool> getter, ValueSetter<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.)

inherited
registerNumericServiceExtension({String name, ValueGetter<double> getter, ValueSetter<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.)

inherited
registerServiceExtension({String name, ServiceExtensionCallback callback }) → void

Registers a service extension method with the given name (full name "ext.flutter.name"). The given callback is called when the extension method is called. The callback must return a Future that either eventually completes to a return value in the form of a name/value map where the values can all be converted to JSON using JSON.encode, or fails. In case of failure, the failure is reported to the remote caller and is dumped to the logs.

inherited
registerSignalServiceExtension({String name, VoidCallback callback }) → void

Registers a service extension method with the given name (full name "ext.flutter.name"), which takes no arguments and returns no value.

inherited
registerStringServiceExtension({String name, ValueGetter<String> getter, ValueSetter<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.

inherited
resetEpoch() → void

Prepares the scheduler for a non-monotonic change to how time stamps are calcuated.

inherited
scheduleFrame() → void

If necessary, schedules a new frame by calling ui.window.scheduleFrame.

inherited
scheduleFrameCallback(FrameCallback callback, { bool rescheduling: false }) int

Schedules the given transient frame callback.

inherited
scheduleTask(VoidCallback task, Priority priority) → void

Schedules the given task with the given priority.

inherited
setSemanticsEnabled(bool enabled) → void

inherited
toString() String

Returns a string representation of this object.
