FlutterUndoManagerPlugin is not released causes the crash (when not initializing FlutterEngine in global scope) #150408
Description
Steps to reproduce
- Enter the Flutter page,
- manipulate the TextView, perform copy and paste operations, generate undo actions,
- exit the Flutter page, and then perform a three-finger slide to undo
Expected results
not crash
Actual results
crash，The root cause is that the FlutterUndoManagerPlugin is not released, while the FlutterEngine has already been released. Attempting to send a message to an object that has been released leads to a crash. In this scenario, the question is whether the FlutterUndoManagerDelegate within FlutterUndoManagerPlugin can be marked with weak.
Code sample
@implementation [FlutterUndoManagerPlugin](https://api.flutter.dev/ios-embedder/interface_flutter_undo_manager_plugin.html) {
id<FlutterUndoManagerDelegate> _undoManagerDelegate;
}
- (instancetype)initWithDelegate:(id<[FlutterUndoManagerDelegate](https://api.flutter.dev/ios-embedder/protocol_flutter_undo_manager_delegate-p.html)>)undoManagerDelegate {
self = [super init];
if (self) {
// `_undoManagerDelegate` is a weak reference because it should retain FlutterUndoManagerPlugin.
_undoManagerDelegate = undoManagerDelegate;
}
return self;
}
