Static Properties
- instance → RendererBinding
-
The current
RendererBinding, if one has been created.read-only
Constructors
Properties
- pipelineOwner → PipelineOwner
-
The render tree's owner, which maintains dirty state for layout, composite, paint, and accessibility semantics
read-only - renderView → RenderView
-
The render tree that's attached to the output surface.
read / write - currentFrameTimeStamp → Duration
-
The time stamp for the frame currently being processed.
read-only, inherited - hashCode → int
-
Get a hash code for this object.
read-only, inherited - hasScheduledFrame → bool
-
Whether this scheduler has requested that handleBeginFrame be called soon.
read-only, inherited - runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited - schedulerPhase → SchedulerPhase
-
The phase that the scheduler is currently operating under.
read-only, inherited - schedulingStrategy → SchedulingStrategy
-
The strategy to use when deciding whether to run a task or not.
read / write, inherited - transientCallbackCount → int
-
The current number of transient frame callbacks scheduled.

Operators
-
operator ==(
other) → bool -
The equality operator.

Methods
-
beginFrame(
) → void -
Pump the rendering pipeline to generate a frame.
-
createViewConfiguration(
) → ViewConfiguration -
Returns a ViewConfiguration configured for the RenderView based on the current environment.
-
handleMetricsChanged(
) → void -
Called when the system metrics change.
-
hitTest(
HitTestResult result, Point position) → void -
Check whether the given position hits this object.
-
initInstances(
) → void -
The initialization method. Subclasses override this method to hook into the platform and otherwise configure their services. Subclasses must call "super.initInstances()".
-
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.
-
initServiceExtensions(
) → void -
Called when the binding is initialized, to register service extensions.
-
reassembleApplication(
) → void -
Called when the ext.flutter.reassemble signal is sent by development tools.
-
setSemanticsEnabled(
bool enabled) → void -
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 -
cancelFrameCallbackWithId(
int id) → void -
Cancels the transient frame callback with the given
id.inherited -
debugAssertNoTransientCallbacks(
String reason) → bool -
Asserts that there are no registered transient callbacks; if there are, prints their locations and throws an exception.
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 -
handleEventLoopCallback(
) → void -
Called by the system when there is time to run tasks.
inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
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
taskwith the givenpriority.inherited -
toString(
) → String -
Returns a string representation of this object.
