Validate non-mandatory fields using Laravel Validation 5.8

Question

I would like to validate a field and make that field not mandatory.

I know that for him to be obligatory I must wear required but I didn’t use it, since I only wanted to validate an email if it was added by the user, so I used validation 'email'.

But it turns out that even I not using the required it by default forces the user to put a value in the field thus leaving the required field. To make it simpler I will put a code below:

namespace App\Http\Requests\Dashboard;

use Illuminate\Foundation\Http\FormRequest;


class FormEditarUsuario extends FormRequest
{

    public function authorize()
    {
        return true;
    }


    public function rules()
    {
        // dd('ok');

        return [
            'email' => 'email'
        ];
    }

    public function messages()
    {

        return [
            'email.email' => 'Campo email inválido'

        ];

    }

}

Summarizing wanted to validate, but in case the user does not put any value in the field it does not return a validation error!

NOTE: I have tried using min:0

Just add the nullable in front:

public function rules()
{
    // dd('ok');

    return [
        'email' => 'nullable|email'
    ];
}
