Scaling widgets

To scale widgets, we use the typical Transform.scale(), constructor. To scale up a widget, for example, we can use it as follows:

Transform.scale(  scale: 2.0,  child: RaisedButton(    child: Text("scaled up"),    onPressed: () {},  ),);

And to get the same result using the default Transform constructor, we use the following:

Transform(  transform: Matrix4.identity()..scale(2.0, 2.0),  alignment: Alignment.center,  child: RaisedButton(    child: Text("scaled up"),    onPressed: () {},  ),);

In a very similar way to the rotation, we must specify both the origin of the transformation with the alignment property and the Matrix4 instance describing the scale transformation.
