flutter 打包apk报错

按照官方文档签名等一些工作配置好了之后。开始使用flutter命令打包apk。在终端执行flutter build apk后等了一段时间后出现如下错误：

BUILD FAILED in 6m 39s

可能由于网络因数，第一次打包不能支持多个平台，那么支持arm平台就可以了。

所以执行命令如下

 flutter build apk --target-platform android-arm

运行之后就可以了，并且下面执行的命令打出的包的体积也要小一些。

 

如果flutter打包出来的apk安装到android手机上可以运行，但是无法访问网络，那么在flutter项目中的android/app/src/main/AndroidMast.xml文件下把网络权限添加上。

不知道为什么在debug模式下不添加是可以访问的。打包之后不添加是不可以的。所以容易疏忽。
