i18n: howto re-render page after catalog change

[maurerdietmar]

We use gettext for i18n, so our code looks like this

 html!{<button>{tr!("Reset")}</button>}

And we want to change the language by simply loading another catalog. Ideally,
I want something like:

if let Some(new_catalog) = new_catalog {
   set_i18n_catalog(new_catalog);
   force_yew_page_redraw(); 
}

The question is how we can implement force_yew_page_redraw()? Is there a function in Yew that allows to clear all state so that all components are newly created (without reloading the page)?

We currently use this workaround:

#[function_component]
fn I18NApp() -> Html {

   ...

    if catlog_change_in_progress {
        html!{}
    } else {
        html! { <HashRouter><DemoApp/></HashRouter> }
    }
}

Any better ideas?
