fix: Failed to authorize:

Description

Probably not a bug just me not knowing how to use the system.

I'm getting an error during the auth process on Android - I have no trouble authing on linux using the same code base.

PlatformException: PlatformException(null_intent, Failed to authorize: Null intent received, null, null)

method_channel_flutter_appauth.dart in MethodChannelFlutterAppAuth.authorize at line 21 within flutter_appauth_platform_interface

My auth code:

 Future<void> _init() async {
    final _scopes = <String>[
      'openid',
      'profile',
      'email',
      'offline_access',
      'accounting.transactions',
      'accounting.contacts'
    ];

    final credentials = await _fetchCredentials();
    manager = OidcUserManager.lazy(
        discoveryDocumentUri: OidcUtils.getOpenIdConfigWellKnownUri(
          Uri.parse('https://identity.xero.com'),
        ),
        clientCredentials: OidcClientAuthentication.clientSecretBasic(
            clientId: credentials.clientId,
            clientSecret: credentials.clientSecret),
        store: OidcDefaultStore(),
        settings: OidcUserManagerSettings(
            scope: _scopes, redirectUri: _getRedirectUrl()));

    // Initialize the manager
    await manager!.init();

  }

Steps To Reproduce The above code is called from a physical Android device (pixel 5 - android 14) and I successfully complete the xero authentication via the browser. Once the auth is complete my app comes to the foreground with the above exception being thrown.

Even if this isn't a bug the lack of useful information in the exception makes this essentially impossible to debug.

The same process/code works without issue on Linux.
