You can Store an object in shared preferences as Below:

SharedPreferences shared_User = await SharedPreferences.getInstance(); Map decode_options = jsonDecode(jsonString); String user = jsonEncode(User.fromJson(decode_options)); shared_User.setString('user', user);              SharedPreferences shared_User = await SharedPreferences.getInstance(); Map userMap = jsonDecode(shared_User.getString('user')); var user = User.fromJson(userMap);          class User {   final String name;   final String age;            User({this.name, this.age});            factory User.fromJson(Map<String, dynamic> parsedJson) {     return new User(       name: parsedJson['name'] ?? "",       age: parsedJson['age'] ?? "");   }            Map<String, dynamic> toJson() {     return {       "name": this.name,       "age": this.age     };   } }
