Dynamic host name and aot

Question

I want to bind a dynamic class name on a component host with this kind of syntax :

@Component({
  host: {
    [`[class.${classNames()}]`]: 'true', 
  },
  selector: '...',
  templateUrl: '...',
})

When I try to build with angular-cli in AOT mode, I have this error :

ERROR in Error encountered resolving symbol values statically. Expression form not supported

How can I make it work?

Thanks
