Flutter why need new when create widget?

Question

Padding(
  child: Icon(Icons.search)
);

new Padding(
  child: new Icon(Icons.search)
);

The above two pieces of code achieve the same effect, when do us need to add "new"?

Flutter need 'new' keyword in the lower version when create a object. In the newest version, 'new' keyword can be ignored
