我在flutter项目中遇到了一些与Firebase相关的错误。
它需要androidx支持，所以我通过此命令创建了一个新项目

flutter create --androidx -t app --org com.giftbaar.flash_chat -a kotlin -i swift flash_chat
flutter pub get运行良好，然后我将项目运行到Android仿真器，这是 flutter run命令的错误

一切正常，并且可以在iOS上运行，但只有Android会产生问题？
解决该问题该怎么办？

最佳答案

更新minSdkVersion:

从:

minSdkVersion 16

到以下内容: 
minSdkVersion 23
