Feature Request: Ability to disable toggle switch

[olsonjb]

I would love to have the ability to disable the toggle switch. My workaround looks something like this:
indicatorColor: isIndicatorDisabled ? Colors.transparent : theme.colorScheme.primary,

Which works for my use case, but does not truly disable the toggle. I would love to be able to pass in a disabled argument to the constructor to prevent interaction. Additionally, I think it would be nice for current to be nullable, and when current is null the indicator is not shown.

I'm sorry for the late reply 😅
A disabled parameter is a good idea. Until I implement such a feature, you can disable the switch by wrapping IgnorePointer and Opacity around AnimatedToggleSwitch.

I'd still have to figure out how to pass that no value is set. Simply setting current to null is currently difficult, as null can also be in values. I could disallow nullable types for the switch but this would be a breaking change.

Currently I don't have much time to implement such features, but I'll get to it as soon as possible.

@olsonjb Should the switch have a lower opacity by default when inactivate, or should it be left to the users to implement this themselves?
