Otherwise the callbacks may be called after FlutterNativeView is destroyed and is null.
Also defensively check for whether the texture is already released in the callback because the callback may be called from another thread by a stale reference (see the comment).
This closes https://github.com/flutter/flutter/issues/20951.
The following were previously marked as deprecated over a month ago:
* `FlutterStandardBigInteger`
* `-[FlutterDartProject initFromDefaultSourceForConfiguration]`
Remove their implementations and mark them as unavailable.
Add a `-[FlutterViewController splashScreenView]` property
Add a `-[FlutterViewController splashScreenView]` property that
clients can use to customize the launch view (issue #17140).
The default WindowManager implementation in Android's Presentation is
delegating addView/removeView/updateViewLayout calls to the global
WindowManager.
This can result in a crash when an embedded view is trying to e.g show a
PopupWindow.
This change adds a custom WindowManager that overrides
addView (and removeView/updateViewLayout) and adds the view to the
presentation's view tree.
Note that views might keep a reference to the window manager which
might be an issue when we move a view from one virtual display to
another (due to a resize). For this reason when re-sizing we are not
creating a new window manager for the new presentation, but updating the
window manager's references to be relevant for the new presentation and
re-use it.
If `FlutterDartProject` found an `FLTLibraryPath` entry in an iOS
application's `Info.plist`, it assumed that values that were valid
filesystem paths were paths to bundles. If the attempt to retrieve
the `NSBundle` fails, `FlutterDartProject` ignored the failure and
then would assign `nil` to a C++ `std::string`, resulting in a null
pointer dereference.
Add some failure checks to prevent this.
