Description
Steps to Reproduce
I was just learning how to use the CupertinoSwitch widget and didn't really know anything. I briefly looked at the docs for it a week before attempting to use it in my app.
I just did
new ListTile(
subtitle: new Text('Birthday Notifications'),
trailing: new CupertinoSwitch(value: null, onChanged: (bool value) {
setState(() {
_birthdayIsOn = value;
});
}),
),because I didn't really know what I was doing. I had previously put in false on the value parameter because I wanted it to start out being false/off and it worked fine. At that point, I also didn't have a good callback, so my Switch wasn't responding to user input. That's when I started experimenting more and put null in for the value.
After the fact, I see that the doc gives a fairly good example, so I recognize that there was more that I could've done to understand how to use it (And I understand it now), but the flutter compiler told me that the error that it gave me wasn't clear and that I should file an issue for this reason.
I've included the Flutter Run results and Flutter Doctor results and I think that is sufficient to file the issue. Nothing in the Flutter Analysis was relavent to this discussion.
