Flutter runで起動できない

Question

前提・実現したいこと

flutter runできない

発生している問題・エラーメッセージ

試したこと

googleで色々と調べるとエラーコードの対応方法が載っていましたが、それに従い、
podfile、podfile.lockの削除を行い、flutter clean, flutter runを行いましたが、上記のエラーが必ず出て起動できなくなってしまいました。すみません、解決方法をお教えください。。

その二行以外にも書かれている事を書いてください

[SteveO]

ありがとうございます。不慣れで恐縮ですが、エラーコード全てを記入いたしました。よろしくお願いいたします。

Answer 1

iosディレクトリが原因だと思います。
iosディレクトリを一回全部消して入れ直した方が早く治る方法だと思います。

rm -rf ios
flutter create -i swift .

削除し、入れ直したら設定が何もやってない状態なので
Podfileを編集します

platform :ios, '10.0'//上の方にコメントアウトされているからここを１０にする

post_install do |installer|//下の方にあるpost_installもこれをコピって上書きする
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
    end
  end
end

上記入力しflutter run行いましたが、エラーがまだ出るようです。出たエラーをエラーコメントに反映させていただきます。
