Replaces the code that attempted to find the topmost presented view controller as the context for presenting a Safari view controller with a call to the new registrar API to get the Flutter view's controller. Since it's now possible for there not to be a view controller, adds an exception for that case. This should only be possible in an add-to-app scenario where someone tries to show an in-app URL from a Flutter view that is not being displayed, which is an unlikely enough scenario that I'm not going to consider this a breaking change. Fixes flutter/flutter#174415

This is copied directly from the recent file_selector_ios PR to adopt UIScene, since we have the same DI needs here.

The view controller provider
Should we call this a ViewControllerPresenterProvider then?

Changed to "The view presenter provider". Because it's just a testability abstraction around a view controller it was hard not to default to calling it a view controller.

Shall we use the same prefix "Test-" above and "Stub-" here?

They don't do the same things; StubViewPresenterProvider is a stub, in that it just returns a fixed value, while TestViewPresenter tracks calls and updates its state (more like a mock).

This refers to the removal of UIApplication.shared.keyWindow?.rootViewController?.topViewController right?

Correct, that's the substantive change here; the rest is testability.

The autopublish step failed, and we didn't catch it. Thanks for flagging that; I've now published it manually. |
