构建 flutter 应用程序时发生错误

Question

我正在尝试使用 Android 工作室使用以下命令构建 flutter 应用程序： flutter build appbundle --target-platform android-arm,android-arm64,android-x64

但我在日志中收到此错误：

E:\User\Application\flutter_application>flutter build appbundle --target-platf
orm android-arm,android-arm64,android-x64
Running "flutter pub get" in flutter_application...                17.1s

我正在使用最新版本的 flutter 2 以及最新版本的 android 工作室，用于 firebase，我将其用于聊天和推送通知。

我尝试了许多解决方案，例如运行 flutter pub get 和 flutter clean ，但似乎没有任何效果，我还尝试重新生成 jks 并重新上传 google_services.json 关于解决方案的任何想法，好吗？

Answer 1

昨天，当我尝试在我的 flutter 应用程序中使用 firebase 时，我也遇到了同样的错误。 作为一个完整的初学者，我对后台发生的事情了解不多，但是通过 web 我发现更改 minSDK 版本可能会有所帮助。 所以，我试了一下，对我来说效果很好。 它现在不会抛出任何错误。 我做了什么？

1. Go 到您的应用程序级别 build.gradle 文件
2. 将 minSdkVersion 更改为 23，最初设置为 16。试一试。 也试试

flutter pub get
flutter pub upgrade
flutter clean
flutter run

否则，通过官方文档选择 go 始终是一个明智的决定。

Answer 2

这是对我有用的解决方案：

flutter pub cache repair
flutter pub get
flutter clean
flutter build
