RenderIgnorePointer constructor
Creates a render object that is invisible to hit testing.
The ignoring argument must not be null. If ignoringSemantics, this
render object will be ignored for semantics if ignoring is true.
Implementation
RenderIgnorePointer({
RenderBox child,
bool ignoring = true,
bool ignoringSemantics
}) : _ignoring = ignoring, _ignoringSemantics = ignoringSemantics, super(child) {
assert(_ignoring != null);
}
