Add Search Widget

• Accepts data list as input
• Option for getting selected item. Returns selected item or null if item is deleted

onItemSelected: (item) {
    //Do whatever you would like
    setState(() {
       _selectedItem = item;
    });
 },

• Option for pop list item builder. This basically returns a widget to show as list item in popup

popupListItemBuilder: (LeaderBoard item) {
   return PopupListItem(item);
 }

• Option for filtering data list based on search query

queryBuilder: (String query, List<LeaderBoard> list) {
   return list.where((LeaderBoard item) => item.username.toLowerCase().contains(query.toLowerCase())).toList();
 }

• Option provided for selected list item builder which enables when a user selects an item from pop up list

selectedItemBuilder: (LeaderBoard selectedItem, deleteSelectedItem) {
   return SelectedItem(selectedItem,deleteSelectedItem);
 }

• Option for providing custom TextField. Accepts TextEditingController and FocusNode as parameter

textFieldBuilder: (TextEditingController controller, FocusNode focusNode) {
    return TextField(
        controller: controller,
        focusNode: focusNode,
        //... Other customizations here
       );
  },
