largeTitleController property
The large title this bar collapses with, if it has one.
Pass the controller the bar shares with its GlassLargeTitle. In iPhone Duo's vertical bar strip the title row holds the large title, so the items that stay horizontal beside it scroll away with it, and the strip hides with the rest of the bar while the title's search is open. Elsewhere it is not read.
Implementation
final GlassLargeTitleController? largeTitleController;
