Transform.translate constructor

Transform.translate({Key key, @required Offset offset, bool transformHitTests: true, Widget child })

Creates a widget that transforms its child using a translation.

The offset argument must not be null. It specifies the translation.

This example shifts the silver-colored child down by fifteen pixels. 
Transform.translate(
  offset: const Offset(0.0, 15.0),
  child: Container(
    padding: const EdgeInsets.all(8.0),
    color: const Color(0xFF7F7F7F),
    child: const Text('Quarter'),
  ),
)

Implementation 

Transform.translate({
  Key key,
  @required Offset offset,
  this.transformHitTests = true,
  Widget child,
}) : transform = Matrix4.translationValues(offset.dx, offset.dy, 0.0),
     origin = null,
     alignment = null,
     super(key: key, child: child);
