I followed this tutorial (https://ws.agency/blog/indexing-flags-drupal-8-flag-search-api), but rather than use the flag as a contextual filter, I wanted the flag available as a field, so that users can look through the view and flag content that interests them.

Is there currently a way to do this with the module? It doesn't seem like it--I've tried many configurations and nothing has worked.

I noticed this issue as well. For some reason there's not any output on the field, but filters work on it. I'd imagine, even if it did work the way it's set up, it would just output user IDs. We probably need to make a special formatter to show the flag link.

I took a stab at fixing this. TBH I'm not 100% sure why it works, but I just followed the documentation for creating a custom processor.
Switched from preprocessIndexItems to addFieldValues to inject the flag values into the index. Can anyone confirm that this is a proper way of fixing the issue?

To build on the last patch, I also added a rudimentary view field handler to expose a flagging link.
I spent a few days trying to figure out how to avoid making extra DB calls, but I came up short. This just overrides the field output with a flag lazy builder. Ideally, I'd like to figure out how to create a relationship on the view to get better performance.
