Flutter：package com.it_nomads.fluttersecurestorage 不存在

Question

I met a problem where when I build the application, it shows there is error where the package is not exists. I am using the example code that provided at pub dev of the dependency flutter_secure_storage . I have already change the minSdkVersion to 18.

Can I know is there any ways to fix this problem?

android\app\src\main\java\io\flutter\plugins\GeneratedPluginRegistrant.java:16: error: package com.it_nomads.fluttersecurestorage does not exist
    flutterEngine.getPlugins().add(new com.it_nomads.fluttersecurestorage.FlutterSecureStoragePlugin());
                                                                         ^

after some search through Google, I have found a solution for my issue through Github. It could be some problem in the pub-cache folder. I follow the comment from one post in Github and deleted flutter_secure_storage inside the pub-cache folder and reinstall and it won't show the error anymore.
