[cssinliner-extra] CssToInlineStyles implicit nullable types deprecations (PHP 8.4)

[smnandre]

CssToInlineStyles (used in twig-extra) package triggers deprecations on PHP 8.4

  1x: TijsVerkoyen\CssToInlineStyles\Css\Property\Processor::convertToObject(): Implicitly marking parameter $specificity as nullable is deprecated, the explicit nullable type must be used instead
    1x in IntegrationTest::testIntegration from Twig\Extra\CssInliner\Tests

  1x: TijsVerkoyen\CssToInlineStyles\Css\Property\Processor::convertArrayToObjects(): Implicitly marking parameter $specificity as nullable is deprecated, the explicit nullable type must be used instead
    1x in IntegrationTest::testIntegration from Twig\Extra\CssInliner\Tests

  1x: TijsVerkoyen\CssToInlineStyles\Css\Property\Property::__construct(): Implicitly marking parameter $specificity as nullable is deprecated, the explicit nullable type must be used instead
    1x in IntegrationTest::testIntegration from Twig\Extra\CssInliner\Tests

I would have created a PR on the package repo, but as the package is compatible with PHP 5.5 i'm not sure what to do ...

AFAIK there is no simple solution for librairies supporting PHP < 7.1 (where nullable argument was introduced)

How is it possible to deal with such situation ?

At this point, I would recommend that the project drops such old versions of PHP.

I've just realised @stof is one of the maintainer (or can merge PR at least - not sure) of CssToInlineStyles. What do you think ? Do we have other alternatives ?

Closing here then.
