A fast and powerful Flutter package helps you sort a list of objects by one or more properties at the same time.
Why?
Suppose you have a list of Phones and you want to sort it according to there specification like RAM, Storage, Price, Camera, etc. at the same time similar to Microsoft Excel sorting.
Suppose I have a list of phones as following.
List<Phone> items = [
Phone("real me 6", 6, 18999, 128),
Phone("real me 6", 8, 19999, 128),
Phone("real Note 8", 7, 16999, 128),
Phone("oppo a9", 4, 13999, 128),
Phone("real me 6 pro", 6, 17999, 64),
Phone("Oppo 5as", 2, 8999, 32),
Phone("Real me 5i", 4, 10999, 64),
Phone("Poco x2", 6, 18500, 128),
]
After sorting in the preference order of first by RAM and then by Storage you will get
[
Phone("real me 6", 8, 19999, 128),
Phone("real Note 8", 7, 16999, 128),
Phone("real me 6", 6, 18999, 128),
Phone("Poco x2", 6, 18500, 128),
Phone("real me 6 pro", 6, 17999, 64),
Phone("oppo a9", 4, 13999, 128),
Phone("Oppo 5as", 2, 8999, 32),
Phone("Real me 5i", 4, 10999, 64),
]
Using this Flutter Package, you can do this Preference Sort/Multiple Sorts/ Multiple level Sorts at the same time very easily.
Installing
1. Depend on it
Add this to your package’s pubspec.yaml file:
dependencies:
multi_sort: ^3.0.0
2. Install it
You can install packages from the command line:
with Flutter:
$ flutter pub get
Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.
3. Import it
Now in your Dart code, you can use:
import 'package:multi_sort/multi_sort.dart';
Documentation
dynamic preferrence
List of properties in which you want to sort the list i.e.List<property> preferrence = ['property1','property2']
first sort the list by property1 then by property2.List<bool> criteria
List of booleans that specifies the criteria of sort i.e., For ascending ordertrue
and for descending orderfalse
.
Usage
Initialization
List<property> list; // List of Items
List<bool> criteria ; //Criteria List
List<String> preferrence ; //prefrrence List
Now sort the list using multisort
list.multisort(criteria, preferrence);
Example
import 'package:flutter/material.dart';
import "package:multi_sort/multi_sort.dart";
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: ExampleApp(),
);
}
}
class ExampleApp extends StatefulWidget {
ExampleApp({Key key}) : super(key: key);
@override
_ExampleAppState createState() => _ExampleAppState();
}
/// Class of Items
class Items {
String name;
int ram;
int price;
int storage;
Items(this.name, this.ram, this.price, this.storage);
///Mapping the properties
Map<String, dynamic> _toMap() {
return {'name': name, 'price': price, 'ram': ram, 'storage': storage};
}
///get function to get the properties of Item
dynamic get(String propertyName) {
var _mapRep = _toMap();
if (_mapRep.containsKey(propertyName)) {
return _mapRep[propertyName];
}
throw ArgumentError('propery not found');
}
}
class _ExampleAppState extends State<ExampleApp> {
//List of Items
List<Items> items = [
Items("real me 6", 6, 18999, 128),
Items("real me 6", 8, 19999, 128),
Items("real Note 8", 7, 16999, 128),
Items("oppo a9", 4, 13999, 128),
Items("real me 6 pro", 6, 17999, 64),
Items("Oppo 5as", 2, 8999, 32),
Items("Real me 5i", 4, 10999, 64),
Items("Poco x2", 6, 18500, 128),
];
// Temp List for sorting
List<Items> sortingList = [];
//Criteria List
List<bool> criteria = [false, false];
//prefrrence List
List<String> preferrence = ['ram', 'storage'];
@override
void initState() {
// TODO: implement initState
super.initState();
setState(() {
sortingList = items;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Sort List Example"),
),
body: Column(
children: [
_buttons(),
ListView.builder(
shrinkWrap: true,
itemCount: sortingList.length,
itemBuilder: (BuildContext context, int i) {
return Card(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text(sortingList[i].name),
Text(sortingList[i].price.toString()),
Text(sortingList[i].ram.toString()),
Text(sortingList[i].storage.toString()),
],
),
);
}),
],
),
);
}
Widget _buttons() {
return RaisedButton(
onPressed: () {
setState(() {
///Sorting using MultiSort
sortingList.multisort(criteria, preferrence);
});
},
child: Text('Sort by preferrence'),
);
}
}
