class AppSecuredPreferences extends SecuredPreferencesService {
static const String _authTokenKey = 'auth_token';
static const String _userIdKey = 'user_id';

AppSecuredPreferences(super.preferences, super.secureStorage);

// no need to encrypt, we use regular SharedPreferences
Future<void> setUserId(String value) {
return preferences.setString(_userIdKey, value);
}

String? get userId => preferences.getString(_userIdKey);

// encrypt sensitive value
Future<void> setAuthToken(String value) {
return secureStorage.write(key: _authTokenKey, value: value);
}

@override
FutureOr<Map<String, String>> getAuthHeaders() async {
// get the authentication token from Secure Storage
final token = await secureStorage.read(key: _authTokenKey);

// return the auth map to inject into API queries
return {
'Authorization': 'Bearer $token'
};
}
