为什么在 android 设备中 运行 项目时会发生与 flutter 相关的 firebase 相关错误？
Why is this firebase related error in flutter happen while running project in android device?
我的 flutter 项目出现了一些与 firebase 相关的错误。
它需要 androidx 支持所以我通过这个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 运行 我的项目到 Android 模拟器，这是我使用 flutter run 命令
的错误
abhishekkumar@Abhisheks-MacBook-Air flash_chat % flutter run

如何解决问题？
更新 minSdkVersion:
发件人：
minSdkVersion 16
以下内容：
minSdkVersion 23
默认情况下，Flutter 支持 Android SDK v16（Jelly Bean，2012 年发布），但 multidex 并不真正适用于 Jelly Bean（尽管有可能）。配置 Jelly Bean 使其正常工作超出了本 Codelab 的范围，因此我们会将最低目标 SDK 版本从 v16 更改为 v21（Lollipop，2014 年发布）。
要更改最低目标 SDK 版本：
打开 android/app/build.gradle，然后找到显示 minSdkVersion 16 的行。
将该行更改为 minSdkVersion 21。
保存文件。
