Trying to migrate the iOS embedder MRC to ARC, I'm attempting to break some dependency cycles so it's easier to migrate the "leaf" dependencies to ARC, working my way up.
The cycle is:
FlutterViewController->FlutterView->FlutterPlatformView-> (Before this PR)FlutterViewControllerFlutterViewControllerdepends on many other large MRC classes, like FlutterEngine., so I'd like to pull that one out soFlutterView,FlutterPlatformView, andFlutterOverlayViewcan be migrated to ARC in a smaller PR.FlutterPlatformViewonly depends onFlutterViewControllerin this one place, casting aUIViewControllerand calling-forceTouchesCancelled:.engine/shell/platform/darwin/ios/framework/Source/FlutterPlatformViews.mm
Line 1201 in 55670b7
Instead, move
-forceTouchesCancelled:to the existingFlutterViewResponderprotocol with the other touch events, whichFlutterViewControlleralready implements. The cast can then be removed, breaking the cycle.Clean up all the imports.
Part of flutter/flutter#137801, though this doesn't actually migrate anything to ARC.
