Firebase電話の認証フラッタークラッシュ

このコードをシミュレーターまたは実際のデバイス（iPhone SE）で実行すると、「確認」ボタンを押すとアプリが停止します。ブレークポイントをデバッグモードにしようとすると、ブレークポイントでアプリが停止しません。最後に、実行中またはフリーズしても例外は発生しません。

よろしくお願いします。よろしくお願いします。

FirebaseURLスキームをInfo.plistに追加する必要があります。 <app_directory>/ios/Runner/Info.plistに移動し、以下を追加します。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.Apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    ...

    <key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleTypeRole</key>
            <string>Editor</string>
            <key>CFBundleURLSchemes</key>
            <array>
                <!-- Insert your reversed client ID here -->

            </array>
        </dict>
    </array>

    ...

REVERSED_CLIENT_IDファイルからGoogleService-Info.plistを取得できます。
