native shared preferences

Migration Shared Preferences #
===========

This plugin is a copy of the shared_preferences package but without the prefix in the keys. Is used to migrate the data from previous native app.
The issue is that flutter add a prefix to the keys when read and write. So we can not read our old keys.
Also for Android you can now specify name of your resource file in android/app/src/main/res/values/strings.xml:
<resources>
...
<string name="flutter_shared_pref_name">resource_name</string>
...
</resources>
