事象

FlutterでiOS用のビルドをしようとした時にエラーが発生してビルドができなかった。

エラーログ

[!] CocoaPods could not find compatible versions for pod "Firebase/DynamicLinks":
  In snapshot (Podfile.lock):
    Firebase/DynamicLinks (= 6.16.0)

  In Podfile:
    firebase_dynamic_links (from `.symlinks/plugins/firebase_dynamic_links/ios`) was resolved to 0.1.0, which depends on
      Firebase/DynamicLinks

It seems like you've changed the constraints of dependency `Firebase/DynamicLinks` inside your development pod `firebase_dynamic_links`.
You should run `pod update Firebase/DynamicLinks` to apply changes you've made.

対応

ログに書いてあるように

pod update Firebase/DynamicLinks

を実行すればOK。
