Method Documentation

◆ applyMutators:embeddedView:boundingRect:

- (void) applyMutators:	(const flutter::MutatorsStack &)	mutatorsStack
embeddedView:	(UIView *)	embeddedView
boundingRect:	(const SkRect &)	boundingRect

◆ bringLayersIntoView:withCompositionOrder:

- (void) bringLayersIntoView:	(const LayersMap &)	layerMap
withCompositionOrder:	(const std::vector< int64_t > &)	compositionOrder

◆ clipViewSetMaskView:

- (void) clipViewSetMaskView: (UIView *) clipView

◆ computeViewsToDispose

- (vector<UIView*> FlutterPlatformViewsController()):

Computes and returns all views to be disposed on the platform thread, removes them from self.platformViews, self.viewsToRecomposite, and self.currentCompositionParams. Any views that still require compositing are not returned, but instead added to viewsToDelayDispose for disposal on the next call.

◆ createLayerWithIosContext:grContext:pixelFormat:

- (void) createLayerWithIosContext:	(const std::shared_ptr< flutter::IOSContext > &)	iosContext
grContext:	(GrDirectContext *)	grContext
pixelFormat:	(MTLPixelFormat)	pixelFormat

Runs on the platform thread.

◆ createMissingOverlays:withIosContext:grContext:

- (void) createMissingOverlays:	(size_t)	requiredOverlayLayers
withIosContext:	(const std::shared_ptr< flutter::IOSContext > &)	iosContext
grContext:	(GrDirectContext *)	grContext

Populate any missing overlay layers.

This requires posting a task to the platform thread and blocking on its completion.

◆ nextLayerInPool

- (shared_ptr<)flutter:

◆ onAcceptGesture:result:

- (void) onAcceptGesture:	(FlutterMethodCall *)	call
result:	(FlutterResult)	result

◆ onCreate:result:

- (void) onCreate:	(FlutterMethodCall *)	call
result:	(FlutterResult)	result

◆ onDispose:result:

- (void) onDispose:	(FlutterMethodCall *)	call
result:	(FlutterResult)	result

◆ onRejectGesture:result:

- (void) onRejectGesture:	(FlutterMethodCall *)	call
result:	(FlutterResult)	result

◆ performSubmit:currentCompositionParams:viewsToRecomposite:compositionOrder:unusedLayers:surfaceFrames:

- (void) performSubmit:	(const LayersMap &)	platformViewLayers
currentCompositionParams:	(std::unordered_map< int64_t, flutter::EmbeddedViewParams > &)	currentCompositionParams
viewsToRecomposite:	(const std::unordered_set< int64_t > &)	viewsToRecomposite
compositionOrder:	(const std::vector< int64_t > &)	compositionOrder
unusedLayers:	(const std::vector< std::shared_ptr< flutter::OverlayLayer >> &)	unusedLayers
surfaceFrames:	(const std::vector< std::unique_ptr< flutter::SurfaceFrame >> &)	surfaceFrames

Update the buffers and mutate the platform views in CATransaction on the platform thread.

◆ removeUnusedLayers:withCompositionOrder:

- (void) removeUnusedLayers:	(const std::vector< std::shared_ptr< flutter::OverlayLayer >> &)	unusedLayers
withCompositionOrder:	(const std::vector< int64_t > &)	compositionOrder

Removes overlay views and platform views that aren't needed in the current frame. Must run on the platform thread.

◆ resetFrameState

- (void) resetFrameState

Resets the state of the frame.

Property Documentation

◆ canApplyBlurBackdrop

- (BOOL) canApplyBlurBackdrop

readwritenonatomicassign

Whether blurred backdrop filters can be applied.

Defaults to YES, but becomes NO if blurred backdrop filters cannot be applied.

Definition at line 198 of file FlutterPlatformViewsController.mm.

◆ compositionOrder

- (vector<int64_t>& FlutterPlatformViewsController()):

readnonatomicassign

view IDs in composition order.

This state is only modified on the raster thread.

Definition at line 169 of file FlutterPlatformViewsController.mm.

◆ currentCompositionParams

- (unordered_map<int64_t,) flutter:

readnonatomicassign

The composition parameters for each platform view.

This state is only modified on the raster thread.

Definition at line 158 of file FlutterPlatformViewsController.mm.

◆ factories

- (unordered_map<)std:

readnonatomicassign

Definition at line 138 of file FlutterPlatformViewsController.mm.

◆ frameSize

- (SkISize) frameSize

readwritenonatomicassign

The size of the current onscreen surface in physical pixels.

Definition at line 146 of file FlutterPlatformViewsController.mm.

◆ gestureRecognizersBlockingPolicies

- (unordered_map<)std:

readnonatomicassign

Definition at line 143 of file FlutterPlatformViewsController.mm.

◆ hadPlatformViews

- (BOOL) hadPlatformViews

readwritenonatomicassign

Whether the previous frame had any platform views in active composition order.

This state is tracked so that the first frame after removing the last platform view runs through the platform view rendering code path, giving us a chance to remove the platform view from the UIView hierarchy.

Only accessed from the raster thread.
