buildWithChild method

@override Widget buildWithChild(BuildContext context, Widget? child)

A build method that receives an extra child parameter.

This method may be called with a child different from the parameter passed to the constructor of SingleChildStatelessWidget. It may also be called again with a different child, without this widget being recreated.

Implementation

@override
Widget buildWithChild(BuildContext context, Widget? child) {
  final padding = this.padding ??
      EdgeInsets.only(
        left: left ?? horizontal ?? all ?? 0.0,
        top: top ?? vertical ?? all ?? 0.0,
        right: right ?? horizontal ?? all ?? 0.0,
        bottom: bottom ?? vertical ?? all ?? 0.0,
      );

  return duration == null
      ? Padding(
          padding: padding,
          child: child,
        )
      : AnimatedPadding(
          padding: padding,
          duration: duration!,
          curve: curve,
          onEnd: onEnd,
          child: child,
        );
}
