dependencies:
...
localstorage: ^4.0.0+1
2- Then run the following command
flutter packages get
3- import the localstorage :
import 'package:localstorage/localstorage.dart';
4- create an instance
class MainApp extends StatelessWidget {
final LocalStorage storage = new LocalStorage('localstorage_app');
...
}
Add item to lcoalstorage :
void addItemsToLocalStorage() {
storage.setItem('name', 'Abolfazl');
storage.setItem('family', 'Roshanzamir');
final info = json.encode({'name': 'Darush', 'family': 'Roshanzami'});
storage.setItem('info', info);
}
Get an item from lcoalstorage:
void getitemFromLocalStorage() {
final name = storage.getItem('name'); // Abolfazl
final family = storage.getItem('family'); // Roshanzamir
Map<String, dynamic> info = json.decode(storage.getItem('info'));
final info_name=info['name'];
final info_family=info['family'];
}
