main.dart 에는 숫자1이 표기 되어 있고,
pubspec.yaml에는 느낌표(!) 표시가 나옵니다.
그리고 아래 메세지와 같이 계속 진행을 못하고 있습니다.
어떤 부분이 잘못 된건가요??

[!] App requires Multidex support
Multidex support is required for your android app to build since the number of methods has exceeded 64k. See https://docs.flutter.dev/deployment/android#enabling-multidex-support for more information. You may pass the --no-multidex flag to skip Flutter's multidex support to use a manual solution.
Flutter tool can add multidex support. The following file will be added by flutter:
