[7.x] Match Symfony's Command::setHidden declaration

[sperelson]

Source of declaration mismatch: Symfony\Component\Console\Command\Command::setHidden(bool $hidden) - vendor/symfony/console/Command/Command.php:456
symfony/console@101b74f

After installing Laravel v7.0.7 on PHP 7.3.12 via laravel new I got a few declaration mismatches with Symfony. Two in Carbon which appear to be documented and with a fix pending here: briannesbitt/Carbon#2033 and this one in
Illuminate\Console\Command::setHidden($hidden) with a mismatch to Symfony\Component\Console\Command\Command::setHidden(bool $hidden)

Installed Symfony is v5.0.5. Errors were displayed in Tinkerwell.

This very well may be a PHP 7.3 issue. Cannot replicate using PHP 7.4

This is a fine fix as method parameter signatures should match if possible. But, my actual problem was that I am a Tinkerwell noob and didn't link my correct PHP version. 🤦‍♂

Meaning that the error was happening because of PHP 7.1....

I'm still experiencing this problem.

  Declaration of Illuminate\Console\Command::setHidden(bool $hidden) should be compatible with Symfony\Component\Console\Command\Command::setHidden($hidden)

Brand new install of Laravel v7.

This happens if you have the wrong version of Symfony in your vendor folder, possibly due to a global install.
