FilterList is a flutter plugin that is designed to provide ease in filter data from a list of strings.

Getting Started

1. Add library to your pubspec.yaml

dependencies:
  filter_list: ^0.0.1

2. Import library in dart file

import 'import 'package:filter_list/filter_list.dart';';

3. How to use FilterList

Create a list of Strings

  List<String> countList = [
    "One",
    "Two",
    "Three",
    "Four",
    "Five",
    "Six",
    "Seven",
    "Eight",
    "Nine",
    "Ten",
    "Eleven",
    "Tweleve",
    "Thirteen",
    "Fourteen",
    "Fifteen",
    "Sixteen",
    "Seventeen",
    "Eighteen",
    "Nineteen",
    "Twenty"
  ];
  List<String> selectedCountList = [];

Create a function and call FilterList.showFilterList() dialog on button clicked

  void _openFilterList() async {
    var list = await FilterList.showFilterList(
      context,
      allTextList: countList,
      height: 450,
      borderRadius: 20,
      headlineText: "Select Count",
      searchFieldHintText: "Search Here",
      selectedTextList: selectedCountList,
    );
    
    if (list != null) {
      setState(() {
        selectedCountList = List.from(list);
      });
    }
  }

Call _openFilterList function on floatingActionButton pressed

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text(widget.title),
        ),
        floatingActionButton: FloatingActionButton(
          onPressed: _openFilterList,
          tooltip: 'Increment',
          child: Icon(Icons.add),
        ),
        /// check for empty or null value selctedCountList
        body: selectedCountList == null || selectedCountList.length == 0
            ? Center(
                child: Text('No text selected'),
              )
            : ListView.separated(
                itemBuilder: (context, index) {
                  return ListTile(
                    title: Text(selectedCountList[index]),
                  );
                },
                separatorBuilder: (context, index) => Divider(),
                itemCount: selectedCountList.length));
  }
