【问题描述】：
将firebase_database: ^7.0.0-dev.2 添加到我的项目后，我一直遇到这个问题。我还在 GitHub、S/O 和 Flutter 存储库上查看了其他问题，但没有成功。
我尝试过的一些故障排除尝试包括：
- 删除
pod文件、Podfile、Podfile.lock等 - 正在运行
flutter clean和flutter pub get - 正在运行
pod install
我创建了一个新的颤振项目并将firebase_core: ^1.1.0 和firebase_database: ^7.0.0-dev.2 添加到pubspec.yaml。因此，我知道问题不是因为与我项目中其他颤振包的依赖冲突。
这是我尝试在模拟器上运行时调试日志的输出：

【问题讨论】：
-
你有没有尝试增加你的部署目标？
-
是的，我阅读了文档以将其增加到版本 10。
-
在每个地方都增加了它？甚至在 pod 中？
-
是的，在 Runner 目标和 Pods 目标中。这是通过 XCode 完成的。
