flutter - Can i store a Map<String, Object> inside a Shared Preferences in dart?

Question

Is there a way that we could save a map object into shared preferences so that we can fetch the data from shared preferences rather than listening to the database all the time. actually i want to reduce the amount of data downloaded from firebase. so i am thinking of a solution to have a listener for shared prefs and read the data from shared prefs.

But i dont see a way of achieving this in flutter or dart.

Please can someone help me to achieve this if there is a workaround.

Many Thanks, Mahi

If you convert it to a string, you can store it

import 'dart:convert';
...
var s = json.encode(myMap);
// or var s = jsonEncode(myMap);

json.decode(...)/jsonDecode(...) makes a map from a string when you load it.
