how active theme works?

[Ivens Pontes]

i have set the 'active' =>'arch' in config/theme.php
but, my views dont take the theme arch.
I'm normally using view('someview') on the controller.
I have to do something for these themes to go to all the views?
If i use middleware works, but i don't want to do it in middleware.

i'm sorry,
missing:

protected $middlewareGroups = [
    'web' => [
        // ...
        \Shipu\Themevel\Middleware\WebMiddleware::class,
    ],
    // ...
];
