@Big Chungus I'm trying to use a MDCDialog in an MVI application. I have a view model which has an open state for the dialog. The dialog may be:
a) closed by some button press by the user, in which case the dialog is closed when it sees the open state of the VM change to false, or
b) closed on scrim or escape, in which case I need to send an event to the VM (using the onClosed hook seems appropriate)

The problem I have is when the dialog is closed via (a), my view model receives two inputs: the button press and the event from the onClosed hook, which causes issues. Is there a way to trigger a callback only for the scrim/escape case?

[Big Chungus]

Dunno, but I don't think so. Have you checked mdc docs for mdc-dialog yet?

[rocketraman]

Yeah, closing and closed are documented as "Indicates when the dialog begins/finishes its closing animation." I'm checking the action value received in the event right now, they don't document what that is.

[Big Chungus]

Looks like acrimClickAction is what you need? https://github.com/material-components/material-components-web/tree/master/packages/mdc-dialog#dialog-actions

[rocketraman]

Ah, so the string just gets set to something else so I can distinguish it. Got it!

[Big Chungus]

Let me know if you manage to get it working

[rocketraman]

Yep, it works. I don't even need to use scrimClickAction and escapeKeyAction because the close event action is undefined (null in Kotlin) if I close the popup through state, and `scrimClickAction`/`escapeKeyAction` (which defaults to close) if done via the scrim/esc.

I'd be curious to check out the website you're building once you have something to show

(assuming it's oss ofc)

[rocketraman]

Not oss, but the site is already live: https://sell.diyoffer.com/. You have to login to see most of it -- feel free to create an account on the test site: https://test.diyoffer.com/home.

Thanks

[Big Chungus]

Did you theme it with css variables or scss mixins?

[Big Chungus]

Looks neat, btw!

[rocketraman]

A small amount of scss but mostly css variables

Looks neat, btw!

Thanks!
