With the new skeleton template (#83530), we need to make sure we run flutter pub get --offline just after flutter create. This is because otherwise, flutter run will not work (see my explanation).

We already do run flutter pub get by default after project creation. https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/commands/create_base.dart#L423-L428
Looks like we might need to either wait a bit (some race condition?), or see if there's something else happening after this line that might mean we need to run it again.

I've volunteered to fix this.
