kita akan pake flutter_secure_storage: ^4.2.0
ubah minSdkVersion jadi 20 di path android/app/build.gradle
minSdkVersion 20
buat file
import 'package:flutter_secure_storage/flutter_secure_storage.dart';
class SecureStorage {
final _storage = FlutterSecureStorage();
Future writeSecureData(String key, String value) async {
var data = await _storage.write(key: key, value: value);
return data;
}
Future readSecureData(String key) async {
var data = await _storage.read(key: key);
return data;
}
Future deleteSecureData(String key) async {
var data = await _storage.delete(key: key);
return data;
}
}
cara gunainnya
import 'package:auth/local_storage.dart';
Future hasToken() async {
final SecureStorage secureStorage = SecureStorage();
final String? token = await secureStorage.readSecureData("token");
if (token != null) return token;
return null;
}
Future setLocalToken(String token) async {
final SecureStorage secureStorage = SecureStorage();
await secureStorage.writeSecureData("token", token);
}
Future unsetLocalToken() async {
final SecureStorage secureStorage = SecureStorage();
secureStorage.deleteSecureData("token");
}
