Flutter: JsObject call document.getElementById

Question

How we can call getElementById using JsObject in flutter, tried below but not worked

import 'dart:js' as js;

var msg = js.context['window'].callMethod(
              'document.getElementById', ["feeds"]);
var msg = js.context.callMethod(
              'document.getElementById', ["feeds"]);

Giving error 

NoSuchMethodError: 'callMethod'

Answer 1

I think the method was supposed to be call() only, as such the error says, there is no callMethod() in JS, if I am being correct.
