MissingPluginException在通道 plugins.flutter.io/firebase_core 上找不到方法 Firebase#initializeC ore 的实现在发布模式下

如何解决MissingPluginException在通道 plugins.flutter.io/firebase_core 上找不到方法 Firebase#initializeC ore 的实现在发布模式下

我正在开发一个使用 firebase 包的应用程序。 它在开发过程中工作正常，但是当我尝试使用 Flutter run --release 发布时，它显示以下错误：

Unhandled Exception: MissingPluginException(No implementation found for method Firebase#initializeC
ore on channel plugins.Flutter.io/firebase_core)
E/Flutter (18843): #0      MethodChannel._invokeMethod (package:Flutter/src/services/platform_channel.dart:157)

E/Flutter (18843): #5      main (package:Flutter_firebase_chat/main.dart:10)
E/Flutter (18843): <asynchronous suspension>

我认为是项目的问题，所以我创建了一个新的 Flutter 项目，我已经复制了 lib 目录并修复了运行项目的所有需要​​。

但在发布模式上仍然存在同样的问题。

这是我的 pusbec.yaml 文件：
