Methods

clearAccessibilityFeaturesTestValue() → void: Deletes any existing test accessibility features and returns to using the real accessibility features.
clearAllTestValues() → void: Delete any test value properties that have been set on this TestPlatformDispatcher and return to reporting the real PlatformDispatcher values for all PlatformDispatcher properties.
clearAlwaysUse24HourTestValue() → void: Deletes any existing test clock format and returns to using the real clock format.
clearDefaultRouteNameTestValue() → void: Deletes any existing test default route name and returns to using the real default route name.
clearLocalesTestValue() → void: Deletes any existing test locales and returns to using the real locales.
clearLocaleTestValue() → void: Deletes any existing test locale and returns to using the real locale.
clearNativeSpellCheckServiceDefined() → void: Deletes existing value that determines whether or not a native spell check service is defined and returns to the real value.
clearPlatformBrightnessTestValue() → void: Deletes any existing test platform brightness and returns to using the real platform brightness.
clearSemanticsEnabledTestValue() → void: Deletes any existing test semantics enabled and returns to using the real semantics enabled.
clearTextScaleFactorTestValue() → void: Deletes any existing test text scale factor and returns to using the real text scale factor.
computePlatformResolvedLocale(List<Locale> supportedLocales) → Locale?: Performs the platform-native locale resolution.
override
getPersistentIsolateData() → ByteData?: The embedder can specify data that the isolate can request synchronously on launch. This accessor fetches that data.
override
noSuchMethod(Invocation invocation) → dynamic: This gives us some grace time when the dart:ui side adds something to PlatformDispatcher, and makes things easier when we do rolls to give us time to catch up.
override
registerBackgroundIsolate(RootIsolateToken token) → void: Registers the current isolate with the isolate identified with by the token. This is required if platform channels are to be used on a background isolate.
override
requestDartPerformanceMode(DartPerformanceMode mode) → void: Requests the Dart VM to adjusts the GC heuristics based on the requested performance_mode.
override
requestViewFocusChange({required int viewId, required ViewFocusState state, required ViewFocusDirection direction}) → void: Requests a focus change of the FlutterView with ID viewId.
override
resetBrieflyShowPassword() → void: Resets brieflyShowPassword to the default value for the platform.
resetFocusedViewTestValues() → void: Clears testFocusEvents and sets currentlyFocusedViewIdTestValue to null.
resetInitialLifecycleState() → void: Resets initialLifecycleState to the default value for the platform.
resetSupportsShowingSystemContextMenu() → void: Resets supportsShowingSystemContextMenu to the default value.
resetSystemFontFamily() → void: Resets systemFontFamily to the default for the platform.
scaleFontSize(double unscaledFontSize) → double: Computes the scaled font size from the given unscaledFontSize, according to the user's platform preferences.
override
scheduleFrame() → void: Requests that, at the next appropriate opportunity, the onBeginFrame and onDrawFrame callbacks be invoked.
override
scheduleWarmUpFrame({required VoidCallback beginFrame, required VoidCallback drawFrame}) → void: Schedule a frame to run as soon as possible, rather than waiting for the engine to request a frame in response to a system "Vsync" signal.
inherited
sendPlatformMessage(String name, ByteData? data, PlatformMessageResponseCallback? callback) → void: Sends a message to a platform-specific plugin.
override
sendPortPlatformMessage(String name, ByteData? data, int identifier, SendPort port) → void: Sends a message to a platform-specific plugin via a SendPort.
inherited
setIsolateDebugName(String name) → void: Set the debug name associated with this platform dispatcher's root isolate.
override
toString() → String: A string representation of this object.
inherited
updateSemantics(SemanticsUpdate update) → void: Change the retained semantics data about this platform dispatcher.
override
view({required int id}) → FlutterView?: Returns the FlutterView with the provided ID if one exists, or null otherwise.
