thickness property Null safety

double thickness

The extend that the owning RenderObject occupies in z-direction starting at elevation.

It's extremely rare to set this value directly. Instead, it is calculated implicitly when other SemanticsConfigurations are merged into this one via absorb.

Implementation

double get thickness => _thickness;
void thickness=(double value)

Implementation

set thickness(double value) {
  assert(value != null && value >= 0.0);
  if (value == _thickness) {
    return;
  }
  _thickness = value;
  _hasBeenAnnotated = true;
}
