Textfield: Typings for on:change and on:input handlers

[throni3git]

Is your feature request related to a problem? Please describe.
I'd like to know what to use as type for the on:input and on:change callbacks in a number Textfield.

Describe the solution you'd like
A clear documentation in the Textfield demo components would be good.

Describe alternatives you've considered
What i already tried is CustomEvent<any> as well as a self defined type

export type EventWithTarget = Event & {
  target: EventTarget & HTMLInputElement;
};

but this was put together from something i read on Stackoverflow and i wonder if there is something official?

CustomEvent<any> does have target: EventTarget | null so i would have to check for target to be non-nullsy. And even then i get the hint Property 'value' does not exist on type 'EventTarget'. This seems a bit cumbersome to me.

Additional context
I am still using SMUI@7 and Svelte@4, but the question is more universal i think.

You'll have to use a ’CustomEvent & InputEvent’ workaround. SMUI 8 with Svelte 5 doesn't need it anymore, but older versions do. There's a demo on the website somewhere. I can't remember where. But also the website is updated for v8, so it would only be available on the v7 branch.
