Android missingpluginexception（在channel plugins.flatter.io/firebase#U core上找不到方法firebase#initializecore的实现）

错误描述 我正在windows桌面上运行我的颤振应用程序 我在android studio中使用主频道，以便在桌面上运行它。 我已经将firebase集成到我的应用程序中，登录注册工作正常，但当我尝试添加或从我的云firestore获取数据时，错误似乎是“没有创建firebase应用程序”[DEFAULT]-在Flatter和firebase中调用firebase.initializeApp（），这通过添加

void main()
async
{
   WidgetsFlutterBinding.ensureInitialized();
   await Firebase.initializeApp();
   // if (USE_FIRESTORE_EMULATOR) {
   //   FirebaseFirestore.instance.settings = Settings(
   //       host: 'localhost:8080', sslEnabled: false, persistenceEnabled: false);
   // }
  runApp(MyApp());
}

到我的应用程序。 但是在添加了这个之后，我得到了一个错误：

发布到：“无”#如果要发布到pub.dev，请删除此行
#下面定义了应用程序的版本和内部版本号。
#版本号是由点分隔的三个数字，如1.2.43
#后跟可选的内部版本号，以+分隔。
#版本和制造商编号都可能在颤振中被覆盖

版本：1.0.0+1
环境：
sdk：“>=2.7.0Flatter Firebase插件，这就是为什么在Windows上运行时没有插件实现。
我不确定为什么人们会反对这个答案。这个问题中出现错误的原因是Windows不存在插件实现。他们在网上找到的错误消息尝试各种解决方案失败的原因是，在这种特殊情况下，错误的来源不是配置错误，而是没有实现。我已经链接到该插件的权威来源，其中列出了它支持的平台，但不包括Windows。我目前正在编写一个桌面颤振应用程序，该应用程序与Android/IOS应用程序共享许多代码，并得到相同的错误。我的应用程序使用了几个没有列出windows的软件包，但没有问题。firedart包明确声明它是“dart本机的”。所以我猜firebase不是“飞镖本地人”。如果有人解释这些“渠道”是什么意思，这将有助于我的理解。从dart到用另一种语言编写的代码的桥梁？最后，我想知道为什么谷歌说Flatter2.2支持Windows，但像Firebase这样的重要软件包还不受支持。@MichaelUhlenberg大多数软件包在所有平台上都能工作；插件是具有本机、特定于平台的代码的包。有关频道的说明，请参阅。至于支持Windows，Firebase本身不支持Windows桌面。没有Windows Firebase SDK，就像iOS和Android一样。Flatter不是Firebase，就像它不是其他插件一样，支持一个平台并不意味着所有可能的插件都会支持这个平台。
