Podfile.lockが生成されない

こんにちは。
FlutterでアプリをBuildしようとしたところ、下のようなエラーが出ました。
調べたところ、Podfile.lock,Podfileを削除することで解決している人が多かったので同じようにしようとしたのですが、Podfile.lockが生成されていないことに気づきました。
ディレクトリはiosを指定しているので本来であればPodfileの下に生成されるはずなのですが、Pod installやPod updateを行なっても生成できません。
原因がわかる方がいらっしゃったらご教授願いたいです。
よろしくお願いします。

↓Podfileは生成されていますがPodfile.lockは生成されていません。

試したこと

Podfileのplatform :iosを9~14の間で変えてみましたが変化はありませんでした。

スクショの下部に pod install に失敗したようなエラーが出てますね。エラーメッセージは端折らずに実行したコマンドも含めて全文貼りましょう。

返事が遅くなりすみません。おっしゃる通りでした。「Rosettaで使用して開く」のチェックを外した後 https://stackoverflow.com/questions/66644365/cocoapods-on-m1-apple-silicon-fails-with-ffi-wrong-architecture を参考に sudo gem uninstall cocoapods sudo gem uninstall cocoapods-core sudo gem uninstall cocoapods-downloader etc. sudo arch -x86_64 gem install ffi sudo arch -x86_64 gem install cocoapods を実行することで解決できました。ありがとうございました。

Finderからターミナルの情報を開き、「Rosettaを使用して開く」のチェックを外した後、
https://stackoverflow.com/questions/66644365/cocoapods-on-m1-apple-silicon-fails-with-ffi-wrong-architecture
を参考に
sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-downloader
etc.
sudo arch -x86_64 gem install ffi
sudo arch -x86_64 gem install cocoapods
を実行することで解決できました。
