simple_storage_plugin #
A plugin for storing data using shared preferences in Android. It is highly dependent on simple_signing_plugin. Stored data is encrypted using AES. In order for the package to function properly, it is required to protect a device with a screen lock.
Features #
This plugin contains following methods:

writeData - saves user's input and key into shared preferences. Authentication is required to perform this action.
readData - reads data from shared preferences saved under input key. If no data under such key is present, an exception is thrown.
deleteData - deletes data from shared preferences saved under input key.
editData - edits data in shared preferences saved under input key. Authentication is required to perform this action.
