how to change font size of flutter material button?

Question

How do I change Font size of a material button... is there a better way to do this?

new MaterialButton(
  height: 140.0,
  minWidth: double.infinity,
  color: Theme.of(context).primaryColor,
  textColor: Colors.white,
  child: new Text("material button"),
  onPressed: () => {},
  splashColor: Colors.redAccent,
),

The widget architecture in Flutter makes this very simple: The child of the MaterialButton is a Text widget, which can be styled with its style property:

new MaterialButton(
  height: 140.0,
  minWidth: double.infinity,
  color: Theme.of(context).primaryColor,
  textColor: Colors.white,
  child: new Text(
    "material button",
    style: new TextStyle(
      fontSize: 20.0,
      color: Colors.yellow,
    ),
  ),
  onPressed: () => {},
  splashColor: Colors.redAccent,
);
