flutter build ios

としたところ、以下のようなエラーが出てきた。

══════════
No valid code signing certificates were found
You can connect to your Apple Developer account by signing in with
your Apple ID
in Xcode and create an iOS Development Certificate as well as a
Provisioning
Profile for your project by:
  1- Open the Flutter project's Xcode target with
       open ios/Runner.xcworkspace
  2- Select the 'Runner' project in the navigator then the 'Runner'
  target
     in the project settings
  3- Make sure a 'Development Team' is selected under Signing &
  Capabilities > Team.
     You may need to:
         - Log in with your Apple ID in Xcode first
         - Ensure you have a valid unique Bundle ID
         - Register your device with your Apple Developer Account
         - Let Xcode automatically provision a profile for your app

Or run on an iOS simulator without code signing

解決法

terminal で ios/Runner.xcworkspace ファイルを開く

open ios/Runner.xcworkspace

こんな感じで xcode が立ち上がる。

Xcodeで「Runner」プロジェクトを選択

「Signing & Capabilities」タブを開く

私の場合、久しぶりのストアアップロードで規約に同意していないのが原因でした。

Unable to process request – PLA Update available
You currently don’t have access to this membership resource. To resolve this issue, agree to the latest Program License Agreement in your developer account.

StoreConnectから同意したらできました。

“Automatically manage signing”（自動管理） をチェック

「Team」のプルダウンから Apple Developer アカウントを選択

「Provisioning Profile」が作成されるのを確認

以上です。

再度以下のコマンドでビルドしなおしましょう。
