I have created users Elasticsearch index in the Google Cloud Platform to integrate firestore cloud functions with Elasticsearch so that when a user is created / updated / deleted, the change will be reflected in the Elasticsearch users index. Now I need to search for users in flutter based on their geolocation. I suppose this will required using username and password in the flutter app.

- Is it save to use Elasticsearch username, and password in flutter?
- What is the best way to handle this.
- Which flutter library is suitable for this job.

I was thinking to create a callable function in firebase and place all logic there. Any ideas?

Thanks in advance.
