After i check in your file , I think you forgot to add default noResultText in your constructor.

Error Line

Wrap(
              spacing: 5,
              runSpacing: 10,
              children: IconPicker.iconMap.length != 0
                  ? iconList
                  : [
                      Center(
                        child: Text(widget.noResultsText +
                            ' ' +
                            SearchBar.searchTextController.text),
                      )
                    ]),

Your Constructor

class IconPicker extends StatefulWidget {
  final double iconSize;
  final String noResultsText;
  static Function reload;
  static Map<String, IconData> iconMap;

  IconPicker({this.iconSize, this.noResultsText, Key key}) : super(key: key);

  @override
  _IconPickerState createState() => _IconPickerState();
}

If i added property noResultsText in FlutterIconPicker.showIconPicker(context, iconSize: 40, noResultsText: 'Not found my bro'); error is gone.

I hope you added default noResultText or make it required in your constructor.
