Handle nullable date.

[GioPat]

The library already allows null values, but when I pass to the DateInput I get this error:

Is there any way to add an element that removes the date from the picker?
Asking this cause my date field is nullable.

[probablykasper]

Null values are not allowed. The value argument can be undefined since it's optional, but the value itself can only be Date.

Not quite sure how this should be implemented 🤔 If value is Date | null, then I assume binding to a Date value wouldn't work.

[GioPat]

Even with the undefined value, I can't manage to have an empty date

[probablykasper]

The argument can be undefined since it's optional and defaults to new Date(), however the value cannot

[GioPat]

Saw that the fallback of undefined is new Date(), in fact there is no way of having a null value for the input. How do you handle the case of a nullable date input field?

[probablykasper]

Once again, the value cannot be null, there's no way for it to have a value other than Date. This is why I was wondering how to implement it.

[GioPat]

I see that the value cannot be null. But I suppose the null can be implemented since the default html 5 input type date supports null value

[probablykasper]

That's why I was wondering how to implement it. The HTML date input is not even a Date though, and it's null value is an empty string.

[GioPat]

I suppose it can be handled with the empty string.

I think issue #3 is related to this.
Say you want to load the component without a date, showing the placeholder value of -- / -- / ----. Currently you can't do it, since the whole placeholder thing does not work as the component loads with a default value set to the current date in the code below:

date-picker-svelte/src/lib/DateInput.svelte

Line 29 in 244b6c5

export let value = defaultDate

would like to vote for this issue - this was a blocker my team to adopt this date picker component. otherwise it's the best one i've seen so far.

Working on a PR for this - it's still a draft and needs some further tweaks, and regression and logging cleanup
