L5 Fresh - ServiceProvider Not Working?

My own ServiceProviders were working fine until I ported them across to a fresh install of L5. The composer is not loading and so I'm not getting any of my composer code.

// remove the rest for brevity
        'Illuminate\View\ViewServiceProvider',
        'Laravel\Socialite\SocialiteServiceProvider',
        'Illuminate\Html\HtmlServiceProvider',
        'Intervention\Image\ImageServiceProvider',


        /*
         * My own app SP
         */
        'App\Providers\TranslatorServiceProvider',

My SP

    /**
     * Registers the decorated translator
     *
     * @return void
     */
    public function register()
    {
        $this->registerLang();
        $this->registerAuthComposer();
    }


    /**
     * Register views to composer  
     */
    private function registerAuthComposer()
    {
        $this->app->view->composer('auth.register.start', TranslatorComposer::class );
        $this->app->view->composer('auth.login', TranslatorComposer::class );
    }


    /**
     * Register the service provider.
     *
     * @return void
     */
    private function registerLang()
    {

        $this->registerLoader();

        $this->app->singleton('translator', function($app)
        {
            $loader = $app['translation.loader'];

            $locale = $app['config']['app.locale'];

            $trans = new Translator($loader, $locale);

            $trans->setFallback($app['config']['app.fallback_locale']);

            return new TranslatorDecorator($trans, $app['config'], $this->app );

        });


    }

\\ excluding the 2 other Laravel methods

My Decorator class

class TranslatorDecorator extends TranslatorResource implements TranslatorInterface
{

    /**
     * Supported Locales
     *
     * @var array
     */
    protected $supportedLocales;

    /**
     * Current locale
     *
     * @var string
     */
    protected $currentLocale = false;

    /**
     * An array that contains all routes that should be translated
     *
     * @var array
     */
    protected $translatedRoutes = array();

    /**
     * Default locale
     *
     * @var string
     */
    protected $defaultLocale;

    /**
     * The actual translator instance
     * @var \Illuminate\Translation\Translator
     */
    protected $translator;
    /**
     * @var Repository
     */
    protected $configRepository;
    /**
     * @var Application
     */
    protected $app;

    /**
     * creates an instance of the decorator
     * @param TranslatorInterface $translator
     */
    public function __construct(TranslatorInterface $translator, Repository $configRepository,  Application $app )
    {
        $this->translator  = $translator;
        $this->configRepository = $configRepository;
        $this->defaultLocale = $this->configRepository->get('app.locale');
        $this->app = $app;
        $this->request = $this->app['request'];
    }
