setlocale() seems to do nothing

Hello,
I want to give my users the option to change their locale (only for their account).
I read the locale can be set by using `$this->request->setLocale('nl');`.
But this still prints 'en'.

PHP Code:

        $this->request->setLocale('nl');
        echo $this->request->getLocale();
       //output: en 


And still the english language files are used.
Is there a way I can dynamicly change the locale (without using the locale in the url) ?

You need to set $supportedLocales:

Updated the docs.

Thanks, that partially did the trick.
Now the getLocale() prints 'nl' instead of 'en'.
Ik have placed '$this->request->setLocale('nl)' on top of my controller method.
But still the english language files are loaded...

If I change the $defaultLocale in Config/App.php it does switch to the NL language files.

You need to run $this->request->setLocale('nl') before calling lang().

Or set locale on Language:

PHP Code:

$language = Services::language();
$language->setLocale('nl');
