how inject dependence for worker function

[QC2168]

I have a dependency property in a function that depends on methods in other modules. I found the localDependency property in the documentation, but it does not solve my problem. So I checked the source code of the useWorker and found that the localDependency property is commented out

// e.g
import {
  diff
} from '@/utils';

import { getConfig } from '@/config';

// my worker function
export default function foo(arr,arr2){
// error, it does not work
//  diff  is not defined
	return diff(arr,arr2);
}
