Search Widget

This Flutter package provides a Search Widget for selecting an option from a data list. It provides the filtering of items based on the search text.

In the dependencies: section of your pubspec.yaml, add the following line:

dependencies:
  search_widget: <latest version>

❔ Usage

Import this class

import 'package:search_widget/search_widget.dart';

Add Search Widget

• Accepts data list as input
• Option for getting the selected items. Returns selected item or null if the 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 a list item in a popup

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

• Option for filtering data list based on a search query

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

• The option provided for selected list item builder which enables when a user selects an item from the 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
       );
  },

Full Implementation

SearchWidget<LeaderBoard>(
   dataList: list,
   hideSearchBoxWhenItemSelected: false,
   listContainerHeight: MediaQuery.of(context).size.height / 4,
   queryBuilder: (String query, List<LeaderBoard> list) {
     return list.where((LeaderBoard item) => item.username.toLowerCase().contains(query.toLowerCase())).toList();
   },
   popupListItemBuilder: (LeaderBoard item) {
     return PopupListItemWidget(item);
   },
   selectedItemBuilder: (LeaderBoard selectedItem, VoidCallback deleteSelectedItem) {
     return SelectedItemWidget(selectedItem, deleteSelectedItem);
   },
   // widget customization
   noItemsFoundWidget: NoItemsFound(),
   textFieldBuilder: (TextEditingController controller, FocusNode focusNode) {
     return MyTextField(controller, focusNode);
   },
 )
