CocoaPods could not find compatible versions

Question

実現したいこと

• CocoaPods could not find compatible versionsを解決させてビルドを成功させる。

前提

Flutterで新しいパッケージ(permission_handler: ^10.3.0)を追加して、保存後pub getしたところ、以下のエラーが発生。

発生している問題・エラーメッセージ

[!] CocoaPods could not find compatible versions for pod "FirebaseFirestore":
  In Podfile:

試したこと

エラー発生後、flutter clean→pub get→flutter runをしたところ、再度同様のエラー発生。

上記のページに記載されている、pod installやpod repo update、pod install --repo-update、pod update、Podfile.lockの削除など試せるものは試したものの解決できず、3時間ほど経過。有識者の方々のお力をお借りしたいと考えています。

Answer 1

cloud_firestoreを4.4.0から4.8.0（最新版）に更新し、pub get、pod install、flutter runを行ったところ、ビルド成功。
どうやら、cloud_firestoreのバージョンが古かったことが原因だったっぽい。
