Flutterfire: [firebase_crashlytics] failed to download settings Error Domain=FABNetworkError Code=-6 "(null)"

When I build the project and it starts I get the following two error messages and nothing is reported:

```bash

Hi @JoshRice1
can you please provide your flutter doctor -v
and your flutter run --verbose?
Also, to better address the issue, would be helpful
if you could post a minimal code sample
or the steps to reproduce the problem.
Thank you

[JoshRice1]

Here are both. I will work on a minimal code sample but have these for you
flutterDoctorOut.txt
output.txt

[JoshRice1]

@iapicca OK here is the minimum code example. It has only the firebase_core and firebase_crashlytics
output.txt
see https://github.com/JoshRice1/firebase_crashlyticbug/ for code example

Any update on this?

[JoshRice1]

Umm so it has been over a month since anyone has put anything in there but me. Any update on the issue? @iapicca

[JoshRice1]

What are you waiting for exactly?

What are you waiting for exactly?

Hi @JoshRice1
I removed the tag waiting for customer response
I didn't add it.
Thank you

Sorry missed the "removed" thanks

I installed the plugin following all instructions on the read me page in my project and every time I was running the project in the simulator I was getting the same issue.

Only after I ran the first time on a real device the problem was fixed.

It does say about Android: "Note: When you are debugging on Android, use a device or AVD with Google Play services. Otherwise, you will not be able to use Firebase Crashlytics."

But it says nothing about iOS. I think the read me should be updated. Also It doesn't say about setting up on Firebase website first, I know this sounds silly but I come from Fabric and not Firebase and in there as soon as you would compile the project the project would be created. So I thought if the project is already created in Firebase we should be fine. But if you press the "Crashlytics" tab in Fabric there is another set up step that should be completed before.
