Route Model Binding in Laravel Package

routing.php

<?php

/**
* Following binding works!
*/

namespace MyPackage\Model;
class User
{
}


namespace App\Http\Controller;
class UserController
{
    public function view(User $user)
    {
      dd($user);
    }
}

// routes/web.php under App\Http\Controller
Route::get(/user/{user}, "UserController@view");


/**
* Following binding doesn't works!
*/

namespace MyPackage\Model;
class User
{
}

class UserController
{
    public function view(User $user)
    {
      dd($user); // is null
    }
}

// routes/web.php under MyPackage\Http\Controller
Route::get(/user/{user}, "UserController@view");

thank you a lot by clarify the solution.
you solved one of my biggest challenges in making a package in the last few days.

Add the following to your Service Provider files boot method.

// top of file
use Illuminate\Support\Facades\Route;

// inside boot method
Route::group([
            'middleware' => ['bindings'],
        ], function () {
            $this->loadRoutesFrom(__DIR__.'/../routes/web.php');
        });
