Improve flutter pub output #110025
Description
Use case
The flutter pub output is not ideal:
PS C:\Code> flutter pub
Missing subcommand for "flutter pub".
Run 'flutter -h' (or 'flutter <command> -h') for available flutter commands and options.
Proposal
Running flutter pub without any subcommands should display the same help text as flutter pub -h:
PS C:\Code> flutter pub
Commands for managing Flutter packages.
Global options:
-h, --help Print this usage information.
-v, --verbose Noisy logging, including all shell commands executed.
If used with "--help", shows hidden options. If used with "flutter doctor", shows additional diagnostic information. (Use "-vv" to force verbose logging in those cases.)
-d, --device-id Target device id or name (prefixes allowed).
--version Reports the version of this tool.
--suppress-analytics Suppress analytics reporting when this command runs.
Usage: flutter pub <subcommand> [arguments]
-h, --help Print this usage information.
Available subcommands:
add Add a dependency to pubspec.yaml.
...
Run "flutter help" to see global options.
