Share data to all views in laravel5.2 - laravel-5

Question

I have the following problem, I want to share an array to all views in my project so I followed the documentation and it works fine, but I want to get the authenticated user in service provider boot function and it always return null ?
any suggestions ?
this is my code
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public $myusers;
public function boot()
{
$origLat=\Auth::user()->lat;
$origLon=\Auth::user()->lng;
$dist=5;
$lon1=$origLon-$dist/cos(deg2rad($origLat))*73.2044736;
$lon2=$origLon+$dist/cos(deg2rad($origLat));
$lat1=$origLat-($dist/73.2044763);
$lat2=$origLat+($dist/73.2044763);
$id=\Auth::user()->id;
$pictures=User::find($id)->pictures;
$this->myusers = DB::table('users')->select(
DB::raw("*,
3956 * 2 *
ASIN(SQRT( POWER(SIN(($origLat- lat)*pi()/180/2),2)
+COS($origLat*pi()/180 )*COS(lat*pi()/180)
*POWER(SIN(($origLon-lng)*pi()/180/2),2)))*1.609344
as distance"
))
->where('users.id', '!=', \Auth::user()->id)
->whereBetween('lng',[$lon1,$lon2])
->whereBetween('lat',[$lat1,$lat2])
->having("distance", "<", "$dist")
->orderBy("distance")
->get();
view()->share('myusers', $this->myusers);
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
}

Unfortunately, at this point the Laravel application request lifecycle works in such a way that when the boot method of the App\Providers\AppServiceProvider class is executed the session is not yet initialised (since that's done in a middleware that is executed after the boot method).
Since the authentication systems needs the session in order to get the authenticated user, in your particular case you can't use view()->share() successfully there (although it's the recommended approach). Instead you can use an alternative approach by doing that in a middleware. Here are the steps that you can follow to make this work:
1. Create a middleware class, let's call it LoadUsers, by running this command:
php artisan make:middleware LoadUsers
2. That will generate a class in app/Http/Middleware/LoadUsers.php. Now you just need to move your code from the AppServiceProvider to the handle method of the middleware:
class LoadUsers
{
public function handle($request, Closure $next)
{
// Your code that shares the data for all views goes here
return $next($request);
}
}
3. Next you need to register the middleware with the App\Http\Kernel class. You can add it to the web group from $routeMiddleware if you want to apply the middleware to all routes that that use that or create your specific group or route middleware. So something like this if you want to add it to web:
protected $middlewareGroups = [
'web' => [
...
// Make sure to add this line is after the
// StartSession middleware in this list
\App\Http\Middleware\LoadUsers::class,
],
...
];
Now you should have the proper shared data for all your views that can depend on Auth::user().
