computeChildOffset method

  1. @override
Offset computeChildOffset(
  1. Offset parentOffset,
  2. Size childSize
)
override

Computes the child's paint offset based on the alignment.

Implementation

@override
Offset computeChildOffset(Offset parentOffset, Size childSize) {
  final double x = parentOffset.x +
      (size!.width - childSize.width) * (alignment.x + 1) / 2;
  final double y = parentOffset.y +
      (size!.height - childSize.height) * (alignment.y + 1) / 2;
  return Offset(x.round(), y.round());
}
