I'm facing the same problem. But in my case, the iOS target version is already 9.0.

My flutter_facebook_login.podspec

My Pod file

pod install error:

Please help me. Thanks in advance.

Your PodFile mark the platform value, you must modify to platform :ios, '9.0'

It worked by uncommenting 2nd line from project pod file. Thanks...
