Solution 1
convert it to a string & save it
prefs.setString('dateTimeString', _dateTime.toIso8601String());
then use DateTime.parse() to retrieve it:
DateTime _dateTime = DateTime.parse(prefs.getString('dateTimeString'));
Solution 2
Also you could take a look at the Flutter Secure Storage package. Here: https://pub.dev/packages/flutter_secure_storage I have used it in my projects and it works like a charm. Its as simple as importing the package and doing this:
import 'package:flutter_secure_storage/flutter_secure_storage.dart';
// Create storage
final storage = new FlutterSecureStorage();
// Read value
String value = await storage.read(key: key);
// Read all values
Map<String, String> allValues = await storage.readAll();
// Delete value
await storage.delete(key: key);
// Delete all
await storage.deleteAll();
// Write value
await storage.write(key: key, value: value);
