Current, I was trying to add `firebase_core: ^0.5.0+1` and `firebase_crashlytics: ^0.2.1+1` packages in my flutter project with the latest versions, It works without any trouble in Android but in iOS, it is not working and giving error. So now how to run my project with the latest package in the iOS Flutter project?

I also tried to `pod repo update` but it is still not working

I am getting this error on `flutter run`

```

    [!] CocoaPods could not find compatible versions for pod "GoogleDataTransport":

      In Podfile:
        firebase_crashlytics (from `.symlinks/plugins/firebase_crashlytics/ios`) was resolved to 0.2.1-1, which depends on
          Firebase/Crashlytics (~> 6.26.0) was resolved to 6.26.0, which depends on

    You have either:
     * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
     * changed the constraints of dependency `GoogleDataTransport` inside your development pod `firebase_crashlytics`.
       You should run `pod update GoogleDataTransport` to apply changes you've made.
