The Qt Quick Ultralite Extras module provides types useful for extra optimizations of Qt Quick Ultralite applications. It is available automatically because all applications are linked to Qul::Core.

And add the following import statement to your .qml file:

import QtQuickUltralite.Extras 2.8.1

Notes:

• The module's version number matches Qt Quick Ultralite's version number.
• Qt Quick Ultralite provides a Qt Quick implementation of the Qt Quick Ultralite Extras QML module.
