Answer 1

Normally composer remove used like this is enough:

$ composer remove vendor/package

but if composer package is removed and config cache is not cleaned you cannot clean it, when you try like so

php artisan config:clear

you can get an error In ProviderRepository.php line 208:

Class 'Laracasts\Flash\FlashServiceProvider' not found

this is a dead end, unless you go deleting files

$rm bootstrap/cache/config.php

And this is Laravel 5.6 I'm talking about, not some kind of very old stuff.

It happens usually on automated deployment, when you copy files of a new release on top of old cache. Even if you cleared cache before copying. You end up with old cache and a new composer.json.
