使用Android Studio构建APK Flutter错误

Question

我想用Android Studio构建APK Flutter。我还在此应用程序中使用了Firestore。当我尝试构建时，出现此错误

我只是想知道与flutter和android同步是否存在任何混乱。在调试过程中，它工作正常。没有错误弹出窗口

Answer 1

我知道它的原因。这是因为图像大小。但是我没有合适的图像大小来构建。

Answer 2

将您的项目迁移到AndroidX。 如果您拥有AndroidStudio 3.2或更高版本，则可以进行重构

Answer 3

您似乎已尝试使用Android Studio构建Flutter APK。您需要转到Flutter控制台，导航到您的项目，然后输入以下命令行：flutter build apk --split-per-abi
