Implementation

@override
void performPaint(PaintingContext context, Offset offset) {

  offset += Offset(renderStyle.paddingLeft.computedValue, renderStyle.paddingTop.computedValue);

  offset += Offset(renderStyle.effectiveBorderLeftWidth.computedValue, renderStyle.effectiveBorderTopWidth.computedValue);

  if (firstChild != null) {
    late DateTime childPaintStart;
    if (kProfileMode && PerformanceTiming.enabled()) {
      childPaintStart = DateTime.now();
    }
    context.paintChild(firstChild!, offset);
    if (kProfileMode && PerformanceTiming.enabled()) {
      DateTime childPaintEnd = DateTime.now();
      childPaintDuration += (childPaintEnd.microsecondsSinceEpoch -
          childPaintStart.microsecondsSinceEpoch);
    }
  }
