You'd be surprised. In Flutter you construct new objects _all the time_ and mostly inline (think React without JSX). The `new`'s really do get tedious when you're making a tree like:

    Container(
      child: Column(
        children: [
          Text("One"), 
          Text("Two"), 
          Text("Three"),
        ]
      )
    )

It's not major but I don't think your quote is overselling it either. It is a quality-of-life change that does those things.
