Hello, do you have any plans to support php 8?
Thank you for your work
I'm working with PHP8, so far it's works

It's correct, i was able to replicate thats error. but you can use PHP 7.4 only for that case:
why do I need to install php 7.4 if the question is support and the ability to install the package using php 8 ?
@barryvdh what do you think about ?
The issue is not laravel-debugbar, but it's dependency (https://github.com/maximebf/php-debugbar). If you take a look at the composer.json, you'll see this package is already ready for PHP 8.
And concerning maximebf/debugbar, it seems like they are already working on PHP 8 compatibility, as the last commits concern tests with PHP 8
Running the tests for PHP8 as we speak, will tag when passing; https://github.com/maximebf/php-debugbar/pull/461
@barryvdh thank you for merging! Thank you for you work!
It's tagged now as 1.16.4, so should be available in a few minutes or so.
all is ok now
