问题---

这里有什么问题？

如何解决此问题？

不需要生成apk连接设备

下面是我为示例项目运行的命令，它已成功构建。使用Android Studio 3.4.1和最新的Flitter sdk，并在我正在运行的Mac机器上运行

$flatter-build-apk

正在初始化gradle。。。2.3s

正在解析依赖项。。。21.8s

调用mockable JAR工件转换以创建文件：

/Users/myname/.gradle/caches/transforms-1/files-1.1/android.jar/0dc309503743c11f537976eb951ae317/android.jar，输入/Users/myname/Library/android/sdk/platforms/android-28/android.jar

正在运行Gradle任务“AssemblereRelease”

正在运行Gradle任务“AssemblereRelease”。。。完成61.0秒
