I believe this is due to a recent change to the “flutter create” command. When I try it from the command line:

"MyAppToday2" is not a valid Dart package name.

**DO** use `lowercase_with_underscores` for package names.

From the [Pubspec format description]
(https://www.dartlang.org/tools/pub/pubspec.html):

Package names should be all lowercase, with underscores to separate words,
`just_like_this`. Use only basic Latin letters and Arabic digits: [a-z0-9_].
Also, make sure the name is a valid Dart identifier -- that it doesn't start

So one issue is that we need to display the output when the command fails.

Thanks for this @branflake2267. I was looking at some related validation and will do some updating to align project creation with the checks in flutter create. (Incidentally, this is tangentially related to proposals for a shareable validation API tracked in https://github.com/dart-lang/linter/issues/654 and https://github.com/dart-lang/linter/issues/657.)

Cheers!
