The <info>%command.name%</info> command generates a new form class. <info>php %command.full_name% UserType</info> If the argument is missing, the command will ask for the form class interactively. You can optionally specify the bound class in a second argument. This can be the name of an entity like <info>User</info> <info>php %command.full_name% UserType User</info> You can also specify a fully qualified name to another class like <info>\App\Dto\UserData</info>. Slashes must be escaped in the argument. <info>php %command.full_name% UserType \\App\\Dto\\UserData</info>
