I was working on this simple app and I can't seem to change the width and height properties of a raised button, I also tried using a flat button but it doesn't work either.Here's a screenshot

Row (mainAxisAlignment: MainAxisAlignment.spaceEvenly,
           children: <Widget>[
             RaisedButton(
               height: 20,
               color: Colors.green,
               onPressed: () {
                 setState(() { });
               },

Error message: The named parameter 'height' isn't defined. Try correcting the name to an existing named parameter's name, or defining a named parameter with the name 'height'.

You should wrap your Raised Button with other widget that pass his contraints, like Container

Container(
  width: 200,
  height: 50,
  child: RaisedButton(
    onPressed: this.action,
    color: Colors.blue,
    child: Text('Title', style: TextStyle(color: Colors.white, fontWeight: FontWeight.bold)),
  ),
)

Isn't the button supposed to have a height property by itself?
RaisedButton does not have a property to set its size by itself. It can inherit constraints from a parent

As you can see in the link raisedButton doc

You need to wrap the button widget with button theme widget after that you are ready to go. I put a example code:

ButtonTheme(
  minWidth: 200.0,
  height: 100.0,
  child: RaisedButton(
    onPressed: () {},
    child: Text("test"),
  ),
);

but why though according to the flutter documentation it should have properties like height and minWidth.
if you check Constructors there is not a properties like height and minWidth. They are under the Properties headline and the button has the properties but to set that you need to use another widget.
but it is listed under properties, I'm getting really confused
