[wkania]

Fix #21022

use Symfony\Component\Form\Extension\Core\Type\DateType;
use Symfony\Component\Form\Extension\Core\Type\DateTimeType;
use Symfony\Component\Form\Extension\Core\Type\TimeType;
use Symfony\Component\Form\Extension\Core\Type\BirthdayType;

$builder->add('from', DateType::class, [
    'input' => 'date_point',
]);
$builder->add('from', DateTimeType::class, [
    'input' => 'date_point',
]);
$builder->add('from', TimeType::class, [
    'input' => 'date_point',
]);
$builder->add('from', BirthdayType::class, [
    'input' => 'date_point',
]);

Thanks @wkania. The first merge in 7.4 branch 🥳

While merging I did some tweaks to add a link to DatePoint docs (because this is not standard in PHP and would be confusing for some folks) and I also added the missing versionadded. See 2276ec1

@javiereguiluz For some reason, I assumed that versionadded didn’t need to be included for LTS versions, since it would be removed in the next release anyway. Probably another project.
