padding property

@override EdgeInsets get padding

The amount to pad the child in each dimension.

If this is set to an EdgeInsetsDirectional object, then textDirection must not be null.

Implementation

@override
EdgeInsets get padding {
  if (renderBoxModelInLayoutStack.isNotEmpty &&
      _layoutPassPaddingCachePassId == renderBoxModelLayoutPassId &&
      _layoutPassPadding != null) {
    return _layoutPassPadding!;
  }

  final EdgeInsets insets = EdgeInsets.only(
    left: _nonNegativePaddingComputedValue(paddingLeft),
    right: _nonNegativePaddingComputedValue(paddingRight),
    bottom: _nonNegativePaddingComputedValue(paddingBottom),
    top: _nonNegativePaddingComputedValue(paddingTop),
  );
  assert(insets.isNonNegative);
  if (renderBoxModelInLayoutStack.isNotEmpty) {
    _layoutPassPaddingCachePassId = renderBoxModelLayoutPassId;
    _layoutPassPadding = insets;
  }
  return insets;
}
