SetLocaleMiddleware class final

Picks the request's locale from ?lang= (or query) or the Accept-Language header, among supported, and makes it the locale of the request: trans, App.locale and validation messages follow it. Without a match the application locale stays.

middleware.use(const [SetLocaleMiddleware(supported: ['en', 'id'])]);
