It seems like $column->getDefault() can also be of type null; however, parameter $args of KitLoong\MigrationsGenerator\Generators\Decorator::columnDefaultToString() does only seem to accept string, maybe add an additional type check?

It seems like $rawType can also be of type null; however, parameter $text of KitLoong\MigrationsGenerator\Support\Regex::getTextBetween() does only seem to accept string, maybe add an additional type check?
