buildLeading method

Widget buildLeading (BuildContext context)

A widget to display before the current query in the AppBar.

Typically an IconButton configured with a BackButtonIcon that exits the search with close. One can also use an AnimatedIcon driven by transitionAnimation, which animates from e.g. a hamburger menu to the back button as the search overlay fades in.

Returns null if no widget should be shown.
