颤动的单信号错误

问题描述

我对颤振中的单信号有很大的疑问。我已经安装了所有程序，现在尝试在main.dart中初始化模块，但是根本没有任何作用，并且在启动应用程序时模拟器关闭了。 这是我的代码： 如您所见，我导入了onesignal模块，并且我有一个名为initPlatformState（）的异步函数，该函数会初始化onesignal。我认为其中一个错误是：

void main() async {
initPlatformState();
}

我认为我不能在void main异步中那样调用它，但是我不知道如何调用它。您认为onesignal需要在main.dart中初始化吗？因为在初始化时会在一个信号上创建用户。我只需要向所有成员发送通知，因此在我的应用程序上创建帐户的人也需要将onesignal存储在我的成员数据库中，以便我仅向在应用程序上赢了钱或钱的成员发送通知
