[📚] Crashlytics doesn't mention you need to enable analytics too.

There's no clear text stating that you need to actually also enable firebase analytics to make the crashlytics work. You can't see any data coming through without enabling firebase analytics.

This is mentioned on Firebase's documentation: https://firebase.google.com/docs/crashlytics/get-started?platform=android#before-you-begin

"Recommended: To automatically get breadcrumb logs to understand user actions leading up to a crash, non-fatal, or ANR event, you need to enable Google Analytics in your Firebase project.

If your existing Firebase project doesn't have Google Analytics enabled, you can enable Google Analytics from the Integrations tab of your settings > Project settings in the Firebase console.

If you're creating a new Firebase project, enable Google Analytics during the project creation workflow."

This issue probably gets unnoticed if you enable firebase analytics right from the start when you create the project in firebase.

🤔 but these two statements don't line up:

you need to actually also enable firebase analytics to make the crashlytics work

vs

Recommended: To automatically get breadcrumb logs to understand user actions leading up to a crash, non-fatal, or ANR event, you need to enable Google Analytics in your Firebase project.

"Need" vs "Recommended"

You do not need analytics to get crashlytics to work. You need crashlytics to get automatic breadcrumbs. That's different isn't it?

Well yes. it doesn't directly state that either. You can't see any data in Firebase though without activating analytics.

That's a strong assertion vs the docs so I tested it

https://github.com/mikehardy/rnfbdemo/tree/crashlytics-no-analytics

I set up a brand new firebase project and I specifically did not set up analytics during project setup. I added a new ios and android app and downloaded their config files.

Then I integrated app and crashlytics only, and added a native crash button and javascript crash button and loaded up the app.

It registered crash reports just fine in the console.

So I am unable to reproduce but I did try.
