generateAuthUrl method

@override Future<String?> generateAuthUrl()

After authorize() is called, to get the authorization header string, (ie, '{scheme} {token}') the client calls this method to generate the raw string.

The returning string formate must always be like

{scheme} {token}

• Example 1: In case of JWT, Bearer {jwt_token}

• Example 2: In case of Basic Auth, Basic {Base64UsernamePassword}

Implementation

@override
Future<String?> generateAuthUrl() async {
  if (!await isAuthenticated()) {
    return null;
  }

  return '$scheme $_encryptedAccessToken';
}
