“Class App\Repositories\TodoInterface does not exist” Laravel 5.5

I'm trying to implement repositories in my application structure.

I cannot find the problem here. I get the following error message:

ReflectionException Class App\Repositories\TodoInterface does not exist

My folder structure is as follows:

  ->app
    ->Repositories
         ->TodoInterface.php
         ->EloquentTodo.php

My TodoInterface.php

<?php
namespace App\Repositories;
interface TodoInterface {
public function getAll();
}

My EloquentTodo.php

<?php
namespace App\Repositories;
use App\Todo;
class EloquentTodo implements TodoInterface
{
/**
 * @var Todo
 */
private $model;
/**
 * EloquentTodo constructor.
 * @param Todo $model
 */
public function __construct(Todo $model)
{
    $this->model = $model;
}
public function getAll()
{
    return $this->model->all();
}   
}

My AppServiceProvide.php

<?php
namespace App\Providers;
use App\Repositories\EloquentTodo;
use App\Repositories\TodoInterface;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    //
}
/**
 * Register any application services.
 *
 * @return void
 */
public function register()
{
    $this->app->bind(
            TodoInterface::class,
            EloquentTodo::class
        );
}
}

My composer.json

"autoload": {
    "classmap": [
        "database/seeds",
        "database/factories"
    ],
    "psr-4": {
        "App\\": "app/",
        "Repositories\\": "app/Repositories/"
    }
},

My TodoController.php

<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Repositories\TodoInterface;
class TodoController extends Controller
{
//
private $todo;
public function __construct(TodoInterface $todo) {
  $this->todo = $todo;
}
public function getAllTodos() {
  return $this->todo->getAll();
}
}

My Route - web.php

Route::get('my-todos','TodoController@getAllTodos');

Can somebody please help me.
