Answer 1

Try to follow this step:

1. Run command flutter clean.
2. Run command pod cache clean --all
3. Remove these files and folders Podfile.lock, .symlinks, Pods
4. Open Podfile, On the top of the file uncomment this line and config minimum iOS platform to 9.0.

Uncomment this line to define a global platform for your project

platform :ios, '9.0'

5. Run command pod repo update
6. Try to run pod install again

i did what @Haniel Baez said i was still getting the same message , in my case i sorted the issue by checking under that path /My_Project/ios/Pods/Local Podspecs/flutter_facebook_auth.podspec.json , inside that json file you'll find the minimum iOS version required for that fbpackage to work in my case it was iOS 10 as shown on the screenshot below

and then you go to your POD File and you uncomment the first line which is by default "platform :ios, '9.0' ", you change it to "platform :ios, '10.0'" as seen on the picture

and you start debugging , as you're debugging you should see new directories getting downloaded to your project under the name FB****** under the PODS Directory as seen on the scrennshots added, and your app should compile and work normally .
