Declaration of Drupal\geolocation_address\Plugin\geolocation\DataProvider\AddressFieldProvider::create must be compatible with...

Hello, @alberto56! Could you please clarify steps to reproduce the issue?

Upon inspection, this was fixed in commit fe2d502d - Issue #3384929 by ChristianAdamski: Fix v4 Testing (10 days ago), where "public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition)" was changed to "public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition): DataProviderInterface" in ./modules/geolocation_address/src/Plugin/geolocation/DataProvider/AddressFieldProvider.php

However it is not included in the 4.0.0-alpha2 release, which I was using.

I will therefore set this to duplicate of #3384929 and starting using the latest dev release, my apologies!
