创建了全新的颤振项目，除了添加到 yaml 之外没有任何变化：

dependencies:
  flutter:
    sdk: flutter
  firebase_core: "0.2.3"

在“包获取”之后，重建项目在 GeneratedPluginRegistrant 中给出错误

**Error:(4, 40) java: package io.flutter.plugins.firebase.core does not exist
Error:(14, 5) java: cannot find symbol
  symbol:   variable FirebaseCorePlugin
  location: class io.flutter.plugins.GeneratedPluginRegistrant
Information:javac 1.8.0_131 was used to compile java sources
Information:5/30/2018 7:18 AM - Compilation completed with 2 errors and 0 warnings in 2 s 101 ms**

您^在版本声明中缺少符号。正确的方法是，

firebase_core: "^0.2.3"

java: package io.flutter.plugins.firebase.core 不存在 这是一个 java 类路径错误。只需添加到类路径
