What is the expected behavior?

md-radio should render and styles are not broken

What is the current behavior?

breaks all the styling and outputs error to console

this is the html that is breaking everything.

<div>
    <h2>Radio Example</h2>
    <md-radio-group>

      <md-radio-button value="option_2">2</md-radio-button>
    </md-radio-group>
 </div>

Yep, as @Neo11 mentions, it won’t work without that provider. Looks like it escaped the documentation, so added an issue for to update the docs: https://github.com/angular/material2/issues/834

Try adding the provider, and if you’re still having issues, please feel free to re-open.

As the thrown error shows, this Provider is missing
