Getting started

To start using the package, add the dependencies in your pubspec.yaml and import.


  1. First, you need a list of items from same Class. Your class model MUST have fromJson & toJson method.

    var list = [
        Contact(1, "Joel McHale"),
        Contact(2, "Danny Pudi"),
        Contact(3, "Donald Glover"),
        Contact(4, "Gillian Jacobs"),
        Contact(5, "Alison Brie"),
        Contact(6, "Chevy Chase"),
        Contact(7, "Jim Rush"),
        Contact(8, "Yvette Nicole Brown"),
        Contact(9, "Jeff Winger"),
        Contact(10, "Abed Nadir"),
        Contact(11, "Troy Barnes"),
        Contact(12, "Britta Perry"),
        Contact(13, "Annie Edison"),
    class Contact {
        final int id;
        final String name;
        Contact.fromJson(Map<String, dynamic> json)
            : id = json['id'],
                name = json['name'];
        Map<String, dynamic> toJson() {
                return {
                'id': id,
                'name': name,
  2. Now you are ready to use the MultiSelectSearch widget.

    • itemBuilder : Build your own list item widgets to select from.


    • chipLabelKey : A field name of your class that should be displayed in selected item chip. In this example, we're displaying Contact's name field value in chip when selected. So it's 'name'

    • items : The list you created in step 1. Both items and itemBuilder must use the same list.

    • initialValue : Some of your list items to be selected beforehand.

    • onChanged : Returns the selected item list everytime a user selects/unselects an item.

    • clearAll : A widget to clear all selected items when clicked. Do not use button widgets.


          itemBuilder: (Contact item) => ListTile(
              key: ObjectKey(item),
              leading: const Icon(Icons.person),
              title: Text(,
          chipLabelKey: 'name',
          items: list,
          initialValue: initial,
          onChanged: (List<Contact> items) =>
              setState(() => selectedItems = items),
          decoration: BoxDecoration(
              color: const Color(0xFFF7A072).withOpacity(0.6),
              border: const Border(
                  bottom: BorderSide(color: Colors.grey),
          clearAll: const Padding(
              padding: EdgeInsets.only(top: 10.0, right: 6.0),
              child: Icon(Icons.clear),
  3. To customize some styles:

    • maxHeight: Search field & selected items container's maximum height when it's expanded.

    • decoration: Search field & selected items container decoration

    • padding: Search field & selected items container padding

    • searchFieldDecoration: InputDecoration to change search field's style, hint text and more.


    • Selected item chip gets its style from the theme. In order to customize it, change chipThemeData in your AppTheme

      theme: ThemeData(
              primarySwatch: Colors.teal,
              chipTheme: const ChipThemeData(
              deleteIconColor: Color.fromARGB(255, 61, 61, 61),
              backgroundColor: Color(0xFFF9F7F3),
