flutter 1.22.2 初始化FlutterViewController 闪退

'-[__NSCFBoolean objectForKey:]: unrecognized selector sent to instance 0x2685b2fe0'

更新flutter后运行Xcode，在初始化FlutterViewController 就崩了

我的初始化代码 

FlutterViewController *flutterVC = [[FlutterViewController alloc]initWithEngine:self.flutterEngine nibName:nil bundle:nil];

  [flutterVCpushRoute:@"welcome"];

有同样问题已解决的吗
