I plan to watch all your keys videos, I have been interested in this topic for a good time. Thanks!

My most valuable tutorial playlist is filled by your videos. We want one full flutter fire base production app course. Doesn’t matter if it’s paid. Kindly consider. Thanks you 😊

Thank You, Johannes. That's a very detail-oriented tutorial.
It would also be very nice if you wrote a written blog too.

I just watched all your recent Key videos, you earned a subscriber!

How about unique key? That should work too, right?

Thank you again, Very useful! Can I ask you something? Lets supose that I have my objects and they are very big (with images inside and files, big strings, etc..). ObjectKey will spend more time to test the objects equality or it doesn't matter?
