Laravel 5.5 Service Provider - laravel-5.5

Question

I am trying to have a custom service provider with common methods that I am using throughout my application. However I am getting an error target not instantiable. I have the same working fine in Laravel 5.3 but now its not working in Laravel 5.5. Here is my code:
In the app\Helpers folder, I have created a folder Contracts with an interface FrontendContracts.
namespace App\Helpers\Contracts;
Interface FrontendContracts{
public function randomString($len);
}
In app\Helpers I have a class FrontendMethods which implements the interface
namespace App\Helpers;
use App\Helpers\Contracts\FrontendContracts;
class FrontendMethods implements FrontendContracts{
public function randomString($len){
$chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmonpqrstuvwxyz";
$result = "";
$charArray = str_split($chars);
for($i = 0; $i < $len; $i++){
$randItem = array_rand($charArray);
$result .= "".$charArray[$randItem];
}
$result .= time();
return $result;
}
}
In the app\Providers I have FrontendServiceProvider class with:
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Helpers\FrontendMethods;
class FrontendServiceProvider extends ServiceProvider{
protected $defer = true;
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot(){
//
}
/**
* Register the application services.
*
* #return void
*/
public function register(){
$this->app->bind('App\Helpers\Contracts\FrontendContracts', function(){
return new FrontendMethods();
});
}
/**
* Get the services provided by the provider.
*
* #return array
*/
public function provides(){
return ['App\Helpers\Contracts\FrontendContracts'];
}
}
I have registered the provider in the providers array as:
App\Providers\FrontendServiceProvider::class,
I am getting the error message Unresolvable dependency resolving [$parameter] in class {$parameter->getDeclaringClass()->getName()}
and Target [App\Helpers\Contracts\FrontendContracts] is not instantiable.
Can someone kindly point at to me what I am doing wrong?

I don't think you need the provides() method in your FrontendServiceProvider class. Try removing this.
