focus method

Future<void> focus(String selector)

This method fetches an element with selector and focuses it. If there's no element matching selector, the method throws an error.

Parameters:

• A selector of an element to focus. If there are multiple elements satisfying the selector, the first will be focused.
• Promise which resolves when the element matching selector is successfully focused. The promise will be rejected if there is no element matching selector.

Implementation

Future<void> focus(String selector) {
  return _secondaryWorld.focus(selector);
}
