Flutter：iOS 构建失败

Question

I have an issue with Flutter. I can't run my app on an iOS simulator. I've tried to create a new certificate under the Mac keychain and that didn't help me much. Does anyone know how I can fix this problem?

The answer is in your flutter doctor:

✗ Flutter plugin not installed; this adds Flutter specific functionality. ✗ Dart plugin not installed; this adds Dart specific functionality.

You will need to fix these issues by setting it all up again as shown here: https://flutter.io/setup-macos/
