class LiveTestWidgetsFlutterBinding

Adds a transient frame callback.

Registers the given object as a binding observer. Binding observers are notified when various application events occur, for example when the system locale changes. Generally, one widget in the widget tree registers itself as a binding observer, and converts the system state into inherited widgets.

Adds a persistent frame callback.

Schedule a callback for the end of this frame.

This is called during test execution before and after the body has been executed.

Takes a widget and attaches it to the renderViewElement, creating it if necessary.

Pump the build and rendering pipeline to generate a frame.

Cancels the transient frame callback with the given id.

Dispatch a PointerCancelEvent for the given pointer soon.

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

Notify all the observers that the locale has changed (using WidgetsBindingObserver.didChangeLocale), giving them the locale argument.

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

Called when the application lifecycle state changes.

Override this method to receive events.

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

Called when the system locale changes.

Called when the system metrics change.

Called when the system pops the current route.

Check whether the given position hits this object.

Acts as if the application went idle.

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

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

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

Tell the framework that the frame we are currently building should not be considered to be a useful first frame.

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

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.)

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.)

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.

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

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.

Unregisters the given observer. This should be used sparingly as it is relatively expensive (O(N) in the number of registered observers).

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

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

Schedules the given transient frame callback.

Schedules the given task with the given priority.

Artificially calls dispatchLocaleChanged on the Widget binding, then flushes microtasks.

Returns the exception most recently caught by the Flutter framework.

Returns a string representation of this object.
