Resolving dependencies of `Podfile`
[!] CocoaPods could not find compatible versions for pod "Firebase/Storage":
In snapshot (Podfile.lock):
Firebase/Storage (= 5.14.0)
In Podfile:
firebase_storage (from `.symlinks/plugins/firebase_storage/ios`) was resolved to 0.0.1, which depends on
Firebase/Storage
It seems like you've changed the constraints of dependency `Firebase/Storage` inside your development pod `firebase_storage`.
You should run `pod update Firebase/Storage` to apply changes you've made.

Error running pod install
script returned exit code 1
Locally we can fix this by doing a pod update, and it works after that. But this is undesirable to do in every build in Jenkins because it will actually change the pod versions, and also it seems very cumbersome to do a pod update, then re-checkout the possibly changed Podfile.lock on every jenkins build.
I wonder if this issue is because the flutter plugins don't set a version in their podspecs?
e.g. here: https://github.com/flutter/plugins/blob/master/packages/firebase_storage/ios/firebase_storage.podspec#L19
