I think this plugin is awesome, but I don't know if it can do this

If you know a way, I would thank you to share it

Better yet, is there a way to know if a document exists?

Jorvan758 commented 4 years ago

Nevermind. Solving this, I learned about try and catch 👍🏽

I don't have access to my project right now, but it's just like:

try
    {
    open_Firestore_document();
    }
catch(NullReferenceException e)
    {
    inform_that_can't_open_Firestore_document();
    }
