bug(md-checkbox): ngChecked directive not working

[brettstack]

According to the doc:

The checkbox directive is used like the normal angular checkbox.

But I am unable to get ngChecked working.

You need to have an ng-model attribute alongside the ng-checked attribute

It works on a standard checkbox fine without an ng-model though.

You're going to need to provide more detail to troubleshoot this issue.
Based on the feedback I'm not sure what you mean by it works on a standard
fine. A plunker or fiddle is not necessary but would go a long way to help
troubleshoot and resolve.

It was supposed to read "standard checkbox" but I put the html element, so it just skipped it. I edited but you mustn't have received an email with the update. http://plnkr.co/edit/KldWCcKJXqQxIKwFQeki?p=preview

​The problem is you're not using ng-model, if you want the checkbox to
default to checked, have the value of the ng-model be truthy and it will be
checked.

Here's a plunker based off yours

Right, but my point is that ng-checked works for standard checkboxes but not md-checkbox. If you look at my original plunkr you will see the standard checkbox does not use ng-model but is still checked because ng-checked is truthy. My use case is I have a checklist directive, and the first checkbox in the checklist is a special "All" checkbox. Checking this unchecks all checked checkboxes, and by checking one again I want the "All" checkbox to be unchecked.

<md-checkbox ng-click="dropdownChecklistCtrl.selected = []", ng-checked="dropdownChecklistCtrl.selected.length === 0">All</md-checkbox>

Sure, I can make this work by using ng-model, but I'd rather not. And since it works with a standard checkbox, this is either a bug with md-checkbox or a documentation issue.

md-checkbox doesn't support checked. If you feel it's necessary you can
submit a pull request that updates the directive scope to accept
ng-checked/checked as an attribute and pass that value when present onto
the input within the directive template.
