Fix mb_strwidth() Passing null to parameter 1 is deprecated #4492

[Polfo]

WHY

BEFORE - What was wrong? What was happening before this PR?

#4492

AFTER - What is happening after this PR?

solved

HOW

How did you achieve that, in technical terms?

?? '' to replace null

Is it a breaking change?

no

How can we test the before & after?

I would be happy to complement a test. I looked at the existing test like tests/Unit/CrudPanel/CrudPanelColumnsTest.php but did not find how to test the blade when null.

[welcome]

BOOM! Your first PR with us, thank you so much! Someone will take a look at it shortly.

Please keep in mind that:

• if this constitutes a breaking change, it might take quite a while for this to get merged; we try to emulate the Laravel release cycle as much as possible, so developers can upgrade both software once; this means a new big release every ~6 months;
• even if it's a non-breaking change, it might take a few days/weeks for the PR to get merged; unless it's a no-brainer, we like to have some community feedback on new features, before we merge them; this leads to higher-quality code, in the end; we learnt this the hard way :-)
• not all PRs get merged; sometimes we just have to hold out new features, to keep the packages lean; sometimes we don't include features that only apply to niche use cases;
• we're not perfect; if you think we're wrong, call us out on it; but in a kind way :-) we all make mistakes, best we learn from them and build better software together;

Thank you!
