I tried to add web support to an existing mobile app. The name of the app in the pubspec.yaml is a valid package name. However, the directory that contains the package (which is derived from a git repository name) contains a dash "-" in the name. Running flutter create . in the package results in:

"xxxxx-xxxxxx" is not a valid Dart package name.

See https://dart.dev/tools/pub/pubspec#name for more information.
