iOS 添加Notification Service Extension 后运行崩溃

在application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions里把
MyFlutterBoostDelegate* delegate= [[MyFlutterBoostDelegate alloc ] init];
[[FlutterBoost instance] setup:application delegate:delegate callback:^(FlutterEngine *engine) {

}];
注释了就不会崩溃

Start at the iOS application:didFinishLaunchingWithOptions entry point and reproduce the crash after adding a Notification Service Extension, keeping the shown FlutterBoost setup enabled. Inspect the crash details and the interaction with MyFlutterBoostDelegate; done means the app launches without crashing while the extension and FlutterBoost initialization are both present.
