flutter packages upgrade; flutter packages get;
如果升级出现新的错误，就去$flutter_root/.pub-cache/hosted/pub.dartlang.org/下删除旧版本的>foundation_fluttify，剩一个最新的版本即可。

尝试了这个也没用

因为之前用的 amap_location 库，然后再 /android/build.gradle 的 dependencies 中加了下面这个

implementation 'com.amap.api:location:latest.integration'

所以删掉就好了。

这个报错信息 android 官方文档 上有说明说是重复依赖导致的。
