you are using package laravel/collective" ? if yes check your facades/alias class in app.php or another options is you can just using asset() helper method link

Also make sure you have the alias as "Html" and not as "HTML" (which I believe is the default). If that is the case make sure you use "HTML" instead of "Html" in your views.

Html is a facade/alias from laravel/collective package.

To install it, got to shell and type: (Laravel 5.4)

composer require "laravelcollective/html":"^5.4.0"

Then, add the provider to the providers array of config/app.php:

Collective\Html\HtmlServiceProvider::class,

Finally, add to the aliases array of config/app.php:

'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,

More info here

Anybody who are using laravel 5.* have to use laravelcollective/html because Package illuminate/html is abandoned, you should avoid using it.

your composer.json file should contain following code in require section(as i am using laravel 5.2 it will be mentioned as 5.2

"laravelcollective/html": "5.2.*"

run composer update

and your config/app.php should contain following code in providers array

'providers' =>

[
                       Collective\Html\HtmlServiceProvider::class,
 
]
and aliases should contain
 
'aliases' => [
 
                'Form' => Collective\Html\FormFacade::class,
                'HTML' => Collective\Html\HtmlFacade::class,
]
 

Its not compatible with current version 5.4.27 now im a i am using the classic html. Thanks for your responses
