This is a very simple abstraction over a Map to allow usage of SessionStorage on any platform, but specifically intended to interact with window.sessionStorage on web without breaking other platforms.
Install the library using your preferred method.
flutter pub add session_storage
Then use the library, the SessionStorage
class only exposes a single constructor, and it always shares the same static instance.
import 'package:session_storage/session_storage.dart';
final session = SessionStorage();
// Use it like you would any other Map.
session['language'] = 'english';
// Sessions are shared, so by calling the constructor again
// you will still have any value you previously set.
final newSession = SessionStorage();
newSession['language'] == 'english' // true
