Forms

use Illuminate\Support\Facades\View;

Now you have to defined the template directory where you have write your html code

alert([ 
    'title' => 'Login Form', 
    'html'  => (string)View::make('vendor.sweetalert.template.login'),
    'showCloseButton' => true,
    'allowOutsideClick' =>false
]);

Now here you can see i am pointing to the views folder actual file path is resources/views/vendor/sweetalert/template/login.blade.php
