Add Toggle implementation

[j-f1]

I think it’s fine to merge this without the toggle style since that’s not super common on the web.

Weird issue: when clicking the “Check me!” checkbox, I get this error: “Fatal error: ToggleStyleKey must have a renderer-provided default value.” Somehow, the default environment values are not being provided.

This is the single defaultValue provided for this key. Thus fatalError is what we get, which needs to change for it to work.

[j-f1]

Yes, but the default environment includes a value for the key:

var environment = EnvironmentValues()
environment[ToggleStyleKey] = AnyToggleStyle(DefaultToggleStyle())

Ah, this may be related to the bug I've seen where mount functions do inject the environment, but update don't. Having a look now...

[MaxDesiatov]

Sorry for the delay, I've stumbled upon a different (but kinda related) bug that I'm finding hard to fix without proper stacktraces, so I'm thinking that the entrypoint/polyfills code in carton needs to be updated to support stacktraces, also hoping to fix swiftwasm/carton#25 at the same time with the update. Yet another rabbit hole for me ¯\_(ツ)_/¯

[j-f1]

No worries! I’m fine waiting.

This may be unblocked with the changes to environment in #170

[j-f1]

Thanks, @carson-katri! The new version seems to be working well, with the caveat that the “I’m always checked!” checkbox can still be unchecked.

[MaxDesiatov]

Would you be able to resolve the conflict please?

[j-f1]

Done!

LGTM, thank you 🙌
