android - 应用程序不在 Release模式下构建

Question

我尝试为我的应用构建一个Realese签名的apk，但是有两个错误。首先是被gradle抛出，就像丢失了一些文件，其次来自firebase消息传递插件。我已经在build.gradle中将CompileSdkVersion设置为28!在使用flutter build apk --split-per-abi命令进行构建之前，我每次都会运行得井井有条。顺便说一句，应用程序 bundle 包的构建没有问题。这是终端的输出

The plugin firebase_core could not be built due to the issue above.

Answer 1

尝试使用旧的Firebase库版本。我遇到了同样的问题，在降级Firebase版本后，它消失了。
