flutter-intellij: Autocompletion not working optimally

Steps to Reproduce

flutter create, then in main.dart take the Text widget in the Center widget, wrap it in a Row widget so that the Text widget is the only element in the children list like so:

body: new Center(
    child: new Row(
      children: <Widget>[
        new Text(
          'Button tapped $_counter time${ _counter == 1 ? '' : 's' }.',
        ),
      ],
    ),
  ), 

Now try to add a new element in the beginning of the list, for instance by typing to “new T” . Here no suggestions are provided. If a “,” is typed after “new T” or the element is added as the last element in the list we get the suggestions.
