excludeFromSemanticsScrolling property

bool excludeFromSemanticsScrolling
@protected

Whether the SemanticsNodes associated with this RenderSliver should be excluded from the semantic scrolling area.

RenderSlivers that stay on the screen even though the user has scrolled past them (e.g. a pinned app bar) should set this to true.

Implementation 

@protected
bool get excludeFromSemanticsScrolling => _excludeFromSemanticsScrolling;
void excludeFromSemanticsScrolling= (bool value)

Implementation 

set excludeFromSemanticsScrolling(bool value) {
  if (_excludeFromSemanticsScrolling == value)
    return;
  _excludeFromSemanticsScrolling = value;
  markNeedsSemanticsUpdate();
}
