"Negative" toast icon change from "whatshot" to "error"

[laurentpayot]

I was surprised to see that the negative type toast displays the social icon whatshot, and that I can't change it. To display error toasts with the material design icon error I have to create toasts with all the options.

Wouldn't an error type toast (with the material design icon error) be useful along with info and warning?

You already have "info" and "warning" Toast types. Please check documentation.
On the icon I felt it was more appropriate to use "whatshot" instead of "error". "error" icon seems milder than the warning. Anyways, pushed patch for the "negative" Toast to use "error" instead of "whatshot".

If there is a solid reason for further changes (let's say like the icon chosen for "negative" Toasts) we can tweak the other "default" types like "info", "warning" and "positive" too.

I knew we already have "info" and "warning" Toast types. My only concern was the icon. If "negative" toasts now have the real "error" icon then I'm happy 👍
