in iOS - Fabric called multiple times

[volkangurol]

• I didnt make Fabric setup

• I only use Firebase plugins (flutter_crashlytics, firebase_analytics, firebase_auth vs.)

• In iOS emulator it shows the message: [Fabric] [Fabric +with] called multiple times. Only the first call is honored, please pass all kits you wish to initialize Is it a known issue ? or analytics may cause problem sending data ?

• Also in iOS setup enabled (dwarf with dsym file) but in crash reports i can not see error line Should i run in release mode or missing something ? any help is appreciated.

• In Android setup there is no kind of this error. (called multiple times)
• In Android crash logs i can see error lines correctly.

[Fabric] [Fabric +with] called multiple times. can you reproduce that with the example app ?

Line number are coming for the dart exception directly so if the line number is not there I don't think I can do anything about it. But from your screenshot you still have the line number on the title 145 and 144 second line

Im getting the same errors as well. For

Fabric +with] called multiple times.

I'm getting it when I click run after the first time.

Im also not getting the right error line on iOS. It is quite confusing.

[jaumard]

Should be good with last version normally :)

I am also getting this error:

[Fabric] [Fabric +with] called multiple times. Only the first call is honored, please pass all kits you wish to initialize

Any idea what's causing this? (I am using flutter_crashlytics and firebase_messaging) and flutter_crashlytics version is 1.0.0.

Also getting this error across the last 3 versions of firebase_crashlytics

firebase_crashlytics is a totally different package

Thanks @jaumard I realized that, but I hoped this would help here, that's why I stated so at the start of my post.

[Fabric] [Fabric +with] called multiple times. looks like an error in Fabric SDK.

This log started appearing since Fabric was introduced into a native project and it is initialized from AppDelegate.application(:, didFinishLaunchingWithOptions:).

So, everything should be good even if it appears in our logs.

[srivasthan]

In ios/Runner/AppDelegate.swift,

Remove

1. import Firebase
2. Firebase.configure

Reason: Firebase was created by Fabric and we try to initialize for second time. Even though they pointed in docs remove and build the application. (Solution only for Flutter projects)
