Removing the ios/Podfile.lock folder, flutter clean, then flutter run again did the trick.

from flutter_plugin_appcenter.

A little more on this. Some people have argued the way to solve this in other places is to put this in the podsfile:
pre_install do |installer|

workaround for CocoaPods/CocoaPods#3289

Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end

When I do that, I does get past the pod install but then fails on compile:
Xcode build done. 10.7s

Encountered error while building for device.

I encountered the same problem.
After researching for several days, I finally found the solution.
The point is to make sure that the pods for appcenter, appcenter_analytics or appcenter_crashes are all built as static library.

@willyliu do you have info on how to do this when you are not familiair with iOS dev?

@dwhiteddsoft Did you find a solution for that issue?
