pre-select radio not working

[wrabit]

Even though the model value is === 0, it is not pre-selecting the radio when:

{!! Form::open()->fill($model !!}
{!! Form::radio('has_tickets', 'No', 0) !!}

<?= $model->has_tickets === 0 ? 'true' : 'false' ?>

Returns 'true';

The issue is caused by type hinting the $value argument as a string in the checkbox and radio methods:

laravel-bootstrap-4-forms/src/FormService.php

Line 440 in a90c5ad

public function radio(string $name = null, string $label = null, string $value = null, bool $checked = null): FormService

Can I ask why? Why not just let the developer pass through their own raw variable. So number can be with or without quotes?
