Feature Request: Please add full code examples

[boustanihani]

It would be great if we always have full code examples that really do work.

For example, if we take a look at the AppShell, in the example code, we can't see what is inside the files "HeadContent.svelte" and "NavContent.svelte", this could make the learning curve for beginners a bit hard..

https://www.svelteui.org/core/app-shell

<script>
	import { fns, AppShell, Navbar, Header, Title, Divider } from '@svelteuidev/core';
	import HeadContent from './HeadContent.svelte';
	import NavContent from './NavContent.svelte';
	...
</script>

Would be great if this applies to all other places where some code is missing :)

Are you willing to create pull request with the fix?

No
