flutter_facebook_login CocoaPods dependency error

Question

I am try add facebook login to Flutter app. I am use flutter_facebook_login. But when I try build for iOS give error:

    Resolving dependencies of `Podfile`
    [!] CocoaPods could not find compatible versions for pod "FBSDKLoginKit":
      In Podfile:
        flutter_facebook_login (from `.symlinks/plugins/flutter_facebook_login/ios`) was resolved to 0.0.1, which depends on
          FBSDKLoginKit (= 4.39.1)

    None of your spec sources contain a spec satisfying the dependency: `FBSDKLoginKit (= 4.39.1)`.

    You have either:
     * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
     * mistyped the name or version.
     * not added the source repo that hosts the Podspec to your Podfile.




Error: CocoaPods's specs repository is too out-of-date to satisfy dependencies.
To update the CocoaPods specs, run:
  pod repo update

Error running pod install
Error launching application on iPhone X.

I no install pod manually because flutter_facebook_login readme say:

(Note: you can skip "Step 2: Set up Your Development Environment").

Anyone help? Thanks!

Answer 1

According to this diegoveloper's answer flutter_facebook_login github issue.

https://github.com/roughike/flutter_facebook_login/issues/201

• flutter clean
• Remove ios/Podfile.lock file
• Go to the Podfile file and changed from platform :ios, '9.0' to platform :ios, '11.0' (In my case, some libs don't support 11.0 and I use platform :ios, '9.0 then set deployment target in runner.xcsworkspace to 9.0 and it work.)
• Go to the terminal , ios directory and run pod install
• Run the project again.

Answer 2

just update your podfile .

platform :ios, '11.0'

try to pod install again in terminal. pod install

Answer 3

1. open terminal and go to root package directory using cd the_root_package_path
2. type flutter clean
3. open podfile and uncomment : # platform :ios, '11.0'
4. run pod install

had the same problem, tried everything, this worked for me.
