I didn't realize this was something I should watch out for since all the tests passed locally/on github 😬... I will keep this in mind in the future lol. Thank you so much for fixing this! |

This is a tricky one and very hard to detect. It could def be improved after we migrate to ARC. |

Fixes flutter/flutter#133776
"The crash is due to testShareScreenInvoked presents the activityViewController, which prevents the engineViewController to be dealloc'd in the test: https://github.com/flutter/engine/blob/main/shell/platform/darwin/ios/framework/Source/FlutterPlatformPlugin.mm#L161C4-L161C24"
This fix stubbing the presentViewController call, which prevents the viewController being alloc'd, thus preventing the leak. It is probably sufficient for this test.
