Persisting data in flutter 2

Persisting data in flutter using key value pair 📱.
As I had mentioned storing data using key value pair is very simple in laravel. Although it has some limitation about type of data that can be saved, for simple purpose like storing api token or user details(not password that would be risky) I don’t think other methods are needed.
To use key value pair storage shared_preference package is used. To store data we have to get an instance of SharedPreference as final prefs = await SharedPreferences.getInstance();. Now to set data prefs.setInt('variableName', value) is enough. Of course to store other datatype setInt will change to setString but that’s about it. Similarly to get the data prefs.getInt('variableName') is used. Depending on the app these functions can be used anywhere but it is good to get initial data value in initState and update it accordingly later using set.
