Flutter – Change search hint text of SearchDelegate

In current implementation of SearchDelegate, there is no option to change the hint text. When the query is empty, search screen is displaying "Search" in the query field as a hint text.

Hint text is currently defined on line 395 as follows:

final String searchFieldLabel = MaterialLocalizations.of(context).searchFieldLabel;

There is, however, an existing issue to this subject reported.

I wasn't able to come up with any solution for this.
Do you know any workaround for the issue?

Solution to answer:

Currently SearchDelegate has an optional member "searchFieldLabel" to specify the label of the search field. It should look something like this:

  @override
  String get searchFieldLabel => 'custom label';
