EdgeInsetsGeometry 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

EdgeInsetsGeometry get padding => _padding;
void padding=(EdgeInsetsGeometry value)

Implementation

set padding(EdgeInsetsGeometry value) {
  assert(value != null);
  assert(padding.isNonNegative);
  if (_padding == value) {
    return;
  }
  _padding = value;
  _markNeedsResolution();
}
