Solution

To Save your info in memory, set sharedprefs using :

SharedPreferences prefs = await SharedPreferences.getInstance();
        if (Platform.isAndroid) {
          AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
          prefs.setString('deviceinfo', androidInfo.id});
          prefs.setString('deviceID', your_android_id_value});
          prefs.setString('deviceName', your_android_name_value});
        } else if (Platform.isIOS) {
          IosDeviceInfo iosInfo = await deviceInfo.iosInfo;
          prefs.setString('deviceinfo', iosInfo.utsname.machine});
          prefs.setString('deviceID', your_ios_id_value});
          prefs.setString('deviceName', your_ios_name_value});
        }

To get info from memory using shared prefs :

SharedPreferences prefs = await SharedPreferences.getInstance();
     String info=prefs.getString("deviceinfo");
     String info=prefs.getString("deviceID");
     String info=prefs.getString("deviceName");
     print("info : ${info}");
     print("ID: ${deviceID}");
     print("Name: ${deviceName}");

This will help you.
