修复步骤 #

• 安装Linux系统依赖
  Firebase Core在Linux上需要特定系统库，执行以下命令安装：

  sudo apt-get install libsecret-1-dev libsqlite3-dev
  

• 验证配置文件位置与引用
  将google-services.json放置在项目的linux/目录下，同时修改linux/CMakeLists.txt，添加配置文件复制逻辑：

  configure_file(${CMAKE_CURRENT_SOURCE_DIR}/google-services.json ${CMAKE_CURRENT_BINARY_DIR}/google-services.json COPYONLY)
  

• 更新依赖并清理项目
  打开pubspec.yaml，确保firebase_core等Firebase插件使用最新稳定版本，然后执行：

  flutter pub get
  flutter clean
  flutter run
  

• 检查Flutter Linux环境完整性
  运行flutter doctor，修复所有提示的Linux开发环境问题，比如缺失的工具链或依赖包。

• 重新配置Firebase项目
  如果上述方法无效，重新执行Firebase配置命令，确保选择正确的项目和Linux平台：

  flutterfire configure
