Exception is thrown when the analytics option was opted out

[NaagAlgates]

Description
An exception is thrown when I opted for no analytics

Steps To Reproduce

1. Go to Terminal
2. Enter very_good --analytics
3. Getting the below exception

Missing argument for "analytics".
#0      CommandRunner.usageException (package:args/command_runner.dart:95:7)
#1      CommandRunner.parse (package:args/command_runner.dart:123:35)
#2      VeryGoodCommandRunner.run (package:very_good_cli/src/command_runner.dart:63:27)
#3      main (file:///Users/xxxxxxxxxx/.pub-cache/hosted/pub.dartlang.org/very_good_cli-0.1.1/bin/very_good.dart:5:54)
#4      _startIsolate.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:299:32)
#5      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:168:12)

Expected Behavior
In my opinion, instead of an exception message, a plain text saying "You have not opted for analytics. To enable it do xxx things"

Hi @NaagAlgates 👋
Thanks for opening an issue!

The --analytics option requires you provide the desired setting:

# enable analytics
$ very_good --analytics true

# disable analytics
$ very_good --analytics false

We'll make sure to improve this in the next release. Thanks for reporting it!🙏

Thank you @felangel ,

I missed the argument "true" or "false"

# disable analytics
$ very_good --analytics false

There is no exception message now. :)
