While running flutter drive tests during the migration of the Google Maps Flutter web plugin, we encountered that certain requests from the Maps JS SDK are blocked with the following error:

Failed to load resource: net::ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep - StaticMapService.GetMapImage:1

When reading some more about the error, one of the recommendations is to use COEP: credentialless instead of require-corp:

Currently Flutter is doing require-corp. Should we switch the tooling to the new value?
