How can I use Illuminate\Session\Middleware\StartSession::class on lumen 5.2

Question

I got this Error:

BindingResolutionException in Container.php line 839:
Unresolvable dependency resolving 
[Parameter #0 [ <required> $app ]] in class Illuminate\Support\Manager

bootstrap/app.php :

$app->middleware([
 Illuminate\Session\Middleware\StartSession::class,
]);

Here's a recap of what needs to be done to activate sessions in Lumen (tested on Lument 5.4):

config/session.php

Download session config from Laravel repo.

bootstrap/app.php

// Load session config (otherwise it won't be loaded)
$app->configure('session');

// Add `Session` middleware
$app->middleware(Illuminate\Session\Middleware\StartSession::class);

// Add `SessionServiceProvider`
$app->register(Illuminate\Session\SessionServiceProvider::class);

// fix `BindingResolutionException` problem
$app->bind(Illuminate\Session\SessionManager::class, function ($app) {    
    return $app->make('session');
});

After that you can access session with app('session') in your controller.
