Flutter開発でFirebaseを導入してiOS Simulatorを起動しようと思い、
flutter runコマンドを叩くと以下のようなエラーが出ました。

Error output from CocoaPods:
↳
[!] Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your
Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.
Error running pod install

shimookakazuhiko@shimookakazuhikonoMacBook-Air my_app % cd ios調べてみるとなんともこれは使っているパッケージのバージョンが変わった際に起こる可能性があるエラーのようです。
Error running pod installの解決方法
iosフォルダの中にある「podfile.lock」を削除し以下のコマンドを叩きます。
cd ios
pod install --repo-update
cd ../ //プロジェクトディレクトリに戻る
flutter clean
flutter run通常はこれで上手くいくようです。
しかし、今回私の環境ではpod install をしたところ以下のようなエラー文が出ました。
[!] CocoaPods could not find compatible versions for pod "firebase_core":
In Podfile:
firebase_core (from `.symlinks/plugins/firebase_core/ios`)
Specs satisfying the `firebase_core (from `.symlinks/plugins/firebase_core/ios`)` dependency were found, but they required a higher minimum deployment target.
[!] Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.
パッケージの firebase_core のバージョンに対して、platformのiOSのバージョンが低いというエラーのようです。
CocoaPods could not find compatible versions for podの解決方法
iosフォルダの中にあるPodfileを編集します。
デフォルトではplatformのバージョンが9.0に設定されており、コメントアウトになっているので
platformのバージョンを上げてコメントアウトを無効にします。
# Uncomment this line to define a global platform for your project
// platform :ios, '9.0'
platform :ios, '12.0'Podfileを編集したら再度以下のコマンドを叩いてみてください。
cd ios
pod install --repo-update
cd ../ //プロジェクトディレクトリに戻る
flutter clean
flutter runこれで上手くいきました。
