android - 您的应用未使用 AndroidX - Flutter 不允许我生成 apk

Question

我在 Mac 上使用 Visual Studio 代码开发了一个应用程序。我在IOS上运行应用程序没有任何问题。我还将它安装在物理设备上并且运行良好，但是在生成 Android 项目研究及其 APK 时出现问题。

Gradle build failed to produce an .aab file. It's likely that this file was generated under

在我自己的情况下，我的 gradle.properties 丢失了。我刚刚在 android 文件夹中创建了一个新的 gradle.properties 文件，具有以下参数

org.gradle.jvmargs=-Xmx1536M
android.useAndroidX=true
android.enableJetifier=true
android.enableR8=true
