dart - How to save to web local storage in flutter web

Question

I have a web site built with flutter for web and currently, am trying to save to web local storage or cookie but can't seem to find any plugin or way to archive that.

Answer 1

You can use window.localStorage from dart:html

import 'dart:html';

class IdRepository {
  final Storage _localStorage = window.localStorage;

  Future save(String id) async {
    _localStorage['selected_id'] = id;
  }

  Future<String> getId() async => _localStorage['selected_id'];

  Future invalidate() async {
    _localStorage.remove('selected_id');
  }
}
