Getting Started

In pubspec.yaml:

dependencies:
  easy_search: any

Important configuration: #

  • If you want to use the Offline List or Local list, do not implement the OnSearch method

  • If you want to fetch data from a web server or an API, do not implement the Offline List or Local List

  • If both OnSearch and the Offline List are implemented, the OnSearch method will prevail and the Offline List will be ignored

Offline list: #

Default Layout:

Simple Offline List
import 'package:easy_search/easy_search.dart';

EasySearch(
  searchResultSettings: SearchResultSettings(
    padding: EdgeInsets.only(left: 8.0, top: 8.0, right: 8.0),
  ),
  controller: SearchItem(
    items: [
      Item(ModelExample(name: 'Tiago', age: 36), false),
      Item(ModelExample(name: 'Mel', age: 3), false),
      Item(ModelExample(name: 'Monique', age: 30), false),
    ],
  ),
),
Custom Layout:
Simple Offline List With Custom Layout
import 'package:easy_search/easy_search.dart';

EasySearch(
  searchResultSettings: SearchResultSettings(
    padding: EdgeInsets.only(left: 8.0, top: 8.0, right: 8.0),
  ),
  controller: SearchItem(
    items: [
      Item(ModelExample(name: 'Tiago', age: 36), false),
      Item(ModelExample(name: 'Mel', age: 3), false),
      Item(ModelExample(name: 'Monique', age: 30), false),
    ],
  ),
  customItemBuilder: (BuildContext context, ModelExample item, bool isSelected) {
    return Container(
      decoration: !isSelected
          ? null
          : BoxDecoration(
              border: Border.all(color: Theme.of(context).primaryColor),
              borderRadius: BorderRadius.circular(7),
              color: Colors.white,
            ),
      child: ListTile(
        selected: isSelected,
        title: Text(item.name),
        subtitle: Text(
          item.age.toString(),
        ),
        leading: Icon(Icons.people),
      ),
    );
  },
),
Multi Select Items:

    items: [
      Item(ModelExample(name: 'Tiago', age: 36), false),
      Item(ModelExample(name: 'Mel', age: 3), false),
      Item(ModelExample(name: 'Monique', age: 30), false),
    ],
  ),
  customItemBuilder: (BuildContext context, ModelExample item, bool isSelected) {
    return Container(
      decoration: !isSelected
          ? null
          : BoxDecoration(
              border: Border.all(color: Theme.of(context).primaryColor),
              borderRadius: BorderRadius.circular(7),
              color: Colors.white,

HTTP Request: #

Default Layout - Http:
From HTTP Request
import 'package:easy_search/easy_search.dart';

EasySearch(
  onSearch: (text) {
    print('Filter Query: $text');
    return getData(name: text);
  },
  searchResultSettings: SearchResultSettings(
    padding: EdgeInsets.only(left: 8.0, top: 8.0, right: 8.0),
  ),
),

.

//HTTP request Example
Future<List<ModelExample>> getData({name}) async {
  var response = await Dio().get(
    "https://5f24717b3b9d35001620456b.mockapi.io/user",
    queryParameters: {"name": name},
  );

  var result = ModelExample.fromJsonList(response.data);
  return result;
}
Custom Layout - Http:
From HTTP Request With Custom Layout
import 'package:easy_search/easy_search.dart';

EasySearch(
onSearch: (text) {
  print('Filter Query: $text');
  return getData(name: text);

    queryParameters: {"name": name},

  var result = ModelExample.fromJsonList(response.data);
  return result;
}

Important About Models #

For the search to work in an offline list, we need to implement the following items in your model or in your object's data class:

toString, equals and also hashcode

Here's how to do it
class ModelExample {
  final String name;
  final int age;

  ModelExample({this.name, this.age});

  @override
  String toString() {
    return '$name $age';
  }

  factory ModelExample.fromJson(Map<String, dynamic> json) {
    if (json == null) return null;
    return ModelExample(
      name: json["name"],
      age: json["age"],
    );
  }

  static List<ModelExample> fromJsonList(List list) {
    if (list == null) return null;
    return list.map((item) => ModelExample.fromJson(item)).toList();
  }
  
  //In this case I customized it so that the search returns everything that contains part of the name or age
  @override
  operator ==(object) => this.name.toLowerCase().contains(object.toLowerCase()) || this.age.toString().contains(object);
  
  @override
  int get hashCode => name.hashCode ^ age.hashCode;
}
