[dart] Space between Column's children in Flutter

You can put a SizedBox with a specific height between the widgets, like so:

Column(
  children: <Widget>[
    FirstWidget(),
    SizedBox(height: 100),
    SecondWidget(),
  ],
),

Why to prefer this over wrapping the widgets in Padding? Readability! There is less visual boilerplate, less indention and the code follows the typical reading-order.
