Class dompdf.wrapper does not exist laravel 4.2.0 - laravel

Question

I am trying to use the dompdf package with Lavarel 4.2.0 in my project authored by barryvdh, I tried installing three different versions of this package (0.6*, 0.6.1,0.5.2)
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"require": {
"laravel/framework": "4.2.*",
"fzaninotto/faker": "^1.6",
"barryvdh/laravel-dompdf": "0.5.2"
How ever each time I try to create a PDF file using
Route::get('/invoice', function()
{
$pdf = App::make('dompdf.wrapper');
$pdf->loadHTML('<h1>Test</h1>');
return $pdf->stream();
});
I get this error
Class dompdf.wrapper does not exist (vendor\laravel\framework\src\Illuminate\Container\Container.php)
/ hand back the results of the functions, which allows functions to be
// used as resolvers for more fine-tuned resolution of these objects.
if ($concrete instanceof Closure)
{
return $concrete($this, $parameters);
}
$reflector = new ReflectionClass($concrete);
// If the type is not instantiable, the developer is attempting to resolve

Answer 1

According to the docs, we need to install the 0.4.x versions for Laravel 4. Your project is using versions for Laravel 5.
composer.json:
"require": {
...
"barryvdh/laravel-dompdf": "0.4.*"
}
To resolve the dompdf service from the container, use 'dompdf', not 'dompdf.wrapper':
$pdf = App::make('dompdf');
Or, use the PDF facade:
use PDF;
...
$pdf = PDF::loadHTML('<h1>Test</h1>');
Be sure to register the service provider and facade in config/app.php.

I put in file config/app.php into providers section:
Barryvdh\DomPDF\ServiceProvider::class,
And into aliases section:
'PDF' => Barryvdh\DomPDF\Facade::class,
And I use this in my controller:
use PDF;
...
$pdf = PDF::loadView('panel.cooperation-offers.pdf', $showData);
Here is my composer.json:
...
"require": {
"php": ">=5.5.9",
"laravel/framework": "5.2.*",
"barryvdh/laravel-dompdf": "0.6.*"
}, ...
