Answer 1

I have managed to solve this issue by changing the Podfile
target 'Runner' do
# flutter Pod
use_frameworks!
use_modular_headers!
------
flutter clean
Delete Podfile.lock
pod install --repo-update
pod update FBSDKLoginKit
Run
flutter clean && cd ios && sudo rm Podfile.lock && pod install --repo-update && pod update FBSDKLoginKit
open .xcworkspace and in General-> Deployment Info set Target 11.0 also in Podfile set Target 11.0

Until now the only way that worked for me was this
You will have to override Podfile.lock with 5.8.0 version of Facebook SDK.
PODS:
- FBSDKCoreKit (5.8.0):
- FBSDKCoreKit/Basics (= 5.8.0)
- FBSDKCoreKit/Core (= 5.8.0)
- FBSDKCoreKit/Basics (5.8.0)
- FBSDKCoreKit/Core (5.8.0):
- FBSDKCoreKit/Basics
- FBSDKLoginKit (5.8.0):
- FBSDKLoginKit/Login (= 5.8.0)
- FBSDKLoginKit/Login (5.8.0):
- FBSDKCoreKit (~> 5.0)
- Flutter (1.0.0)
....

Answer 3

I've been around the houses and back with this and have eventually got this to work with the 5.13.1 Podfiles on iOS (by work, I mean compiling, linking and installing onto a real iPhone - I don't actually use Facebook but it's required as part of the firebase-ui login package :-D )
Firstly, do a pod clean, e.g.
Run: flutter clean
Go to ios folder, delete Podfile, Podfile.lock, Pods folder, Runner.xcworkspace
Run project again
After building I got errors regarding:
fatal error: module 'FBSDKCoreKit' not found
#import FBSDKCoreKit;
I then added the modular headers override into the ios/podspec file mentioned here https://github.com/roughike/flutter_facebook_login/issues/214#issuecomment-565166295
The start of the podfile looks like this:
platform :ios, '12.0'
use_modular_headers!
I did note that linking errors, about missing Facebook libraries, were due to a spurious entry in the Frameworks section.

I had resolved it by following below steps, I had faced this issue due to facebook_share plugin so
1.downgrade the version of facebook_share plugin to. 0.0.1+1
2.run command in your project's terminal - pod cache clean —all
3.add below two pods in Podfile:
target 'Runner' do
use_frameworks!
use_modular_headers!
pod 'FBSDKCoreKit', '~> 6.0.0'
pod 'FBSDKShareKit', '~> 6.0.0'
4.run command in your project's terminal - Pod install
5.run command in your project's terminal - pod update FBSDKShareKit
done, error removed

This issue solved my problem 'FBSDKCoreKit / FBSDKCoreKit.h' file not found
pod 'FBSDKCoreKit', '4.38'
pod 'FBSDKLoginKit', '4.38'
pod 'FBSDKShareKit', '4.38'
