hasImplicitScrolling property

bool hasImplicitScrolling

Whether the platform can scroll the semantics node when the user attempts to move focus to an offscreen child.

For example, a ListView widget has implicit scrolling so that users can easily move to the next visible set of children. A TabBar widget does not have implicit scrolling, so that users can navigate into the tab body when reaching the end of the tab bar.

Implementation 

bool get hasImplicitScrolling => _hasFlag(SemanticsFlag.hasImplicitScrolling);
void hasImplicitScrolling= (bool value)

Implementation 

set hasImplicitScrolling(bool value) {
  _setFlag(SemanticsFlag.hasImplicitScrolling, value);
}
