cloud_music's Issues

单例模式栈溢出

我看你项目里有这一段代码,你这里不会栈溢出吗?我把你的代码拷贝到vscode,然后new一个AppStatusModel就会栈溢出

class AppStatusModel {
  static AppStatusModel _singleton;
  factory AppStatusModel() => _getInstance();
  static AppStatusModel _getInstance(){
    if(_singleton == null){
      _singleton = AppStatusModel();
    }
    return _singleton;
  }
}

测试代码

main(List<String> args) {
  var app = AppStatusModel();
}

class AppStatusModel {
  static AppStatusModel _singleton;
  factory AppStatusModel() => _getInstance();
  static AppStatusModel _getInstance() {
    if (_singleton == null) {
      _singleton = AppStatusModel();
    }
    return _singleton;
  }
}
