fitted_scale 1.0.2

A widget that scales its child prior to layout, the final rendering box consumes only as much space as required by the scaled child.

Fitted scale is a widget that scales its child prior to layout. Unlike Transform.scale(), which applies a transform just prior to painting, this widget applies its scaling prior to layout, which means the entire rendered box consumes only as much space as required by the scaled child. You may think of this as the scaling version of RotatedBox.

Usage

Scale your widget in a similar way as Transform.scale()

Apply a uniform scaling:

FittedScale(
  scale: 0.6,
  child: FlutterLogo( size: 110 )
),

Specify horizontal and/or vertical scaling independently:

FittedScale(
  scaleX: 0.6,
  scaleY: 1.3,
  child: FlutterLogo( size: 110 )
),

More examples

This is an example of scaling up an material IconButton. The finally layout is more desirable compared to adopting Transform.scale().

Row(children: [
  FittedScale(
    scale: 2.0,
    child: IconButton( onPressed: () {}, icon: Icon(Icons.read_more))),
  Container(
    color: Colors.green,
    child: FlutterLogo( size: 110 ),
  ),
])

Performing scaling prior to layout can sometimes avoid unwanted clipping.

Row(children: [
  Container(
    color: Colors.amber,
    child: FittedScale(
        scaleX: 2.4,
        child: FlutterLogo( size: 110 )),
  ),
  Container(
    color: Colors.green,
    child: FittedScale(
      scaleY: 0.75,
      child: FlutterLogo( size: 110 )),
  ),
]),

Notice that if the above is implemented with Transform.scale(), two sides of the Flutter logo(yellow background) will be trimmed.
