hope you are fine,

The best solution is to use a local database, but if you insist to use shared preferences, you can do this approach:

1. Encode the JSON and convert it to String.
2. Save the string in the SharedPref.
3. When you want to retrieve it -> get the String from SharedPref -> use json decode to decode it -> you will get. the Map (JSON) -> convert it to a list of addresses.
