Laravel Mail - New methods with interesting parameter passing

Question

I am wondering here by the parameter passing in the new Laravel Mail class. My IDE (VSCode) also underlines the parameter and throws the following error: syntax error, unexpected ':', expecting ')'

public function envelope()
{
    return new Envelope(
        subject: 'Subject', // <-- the key subject
        from: 'test@test.fr', // <-- the key from
    );
}

Nevertheless, it works. It's probably a new PHP specification that I don't know yet. What is it called and does it work? And how can I teach my IDE that it is not an error?

Answer 1

you can write code in this syntax

public function envelope()
{
    return $this->view('mail.welcome') // <-- View File Name
        ->from('test@test.fr')
        ->subject('Subject')
}
