How to implement Pull to Refresh in Flutter?

“Have you ever wondered what it takes to completely transform your daily routine into a powerhouse of productivity and joy?”

hello guys, I hope you all are doing well. So right now, we are learning and creating Pul to Refresh in Flutter. first, we understand what a pull to refresh and why we use it in our application. Now we understand what a Pull refresh is.

Pull Refresh

To refresh, pull. A common UX paradigm in mobile applications is Flutter, which lets users manually reload the content of a scrollable screen. Users may easily update the data shown without switching screens or using a separate refresh button, thanks to the pattern.

So don’t westing your time; we’re implementing Pull to refresh step-by-step.

Step 1: Open your project and implement one package, liquid_pull_to_refresh 3.0.1

Open your project terminal and paste this command

flutter pub add liquid_pull_to_refresh

Step 2: Open your main.dart file and navigate to your home page In my case, we navigate to HomePage.dart file

import 'package:flutter/material.dart';
import 'package:forarticles/Pages/HomePage.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home:  HomePage(),
      //   home:  OnBordingScreen(),
    );
  }
}

Step 3: Create new dart file and name it HomePage.dart and paste this code

import 'package:flutter/material.dart';
import 'package:liquid_pull_to_refresh/liquid_pull_to_refresh.dart';

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  State<HomePage> createState() => _HomePageState();
}


Future<void> _handelRefresh() async{
  return await Future.delayed(Duration(seconds: 2));
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.grey[200],
      body: LiquidPullToRefresh(
        onRefresh: _handelRefresh,
        color: Colors.deepOrangeAccent,
        height: 300,
        backgroundColor: Colors.green[200],
        animSpeedFactor: 2,
        child: ListView(
          children: [
            
            Padding(
              padding: const EdgeInsets.all(25.0),
              child: ClipRRect(
                borderRadius: BorderRadius.circular(15),
                child: Container(
                  height: 300,
                  color: Colors.deepOrangeAccent,
                ),
              ),
            ),
        
            Padding(
              padding: const EdgeInsets.all(25.0),
              child: ClipRRect(
                borderRadius: BorderRadius.circular(15),
                child: Container(
                  height: 300,
                  color: Colors.deepOrangeAccent,
                ),
              ),
            ),
        
            Padding(
              padding: const EdgeInsets.all(25.0),
              child: ClipRRect(
                borderRadius: BorderRadius.circular(15),
                child: Container(
                  height: 300,
                  color: Colors.deepOrangeAccent,
                ),
              ),
            ),
        
            Padding(
              padding: const EdgeInsets.all(25.0),
              child: ClipRRect(
                borderRadius: BorderRadius.circular(15),
                child: Container(
                  height: 300,
                  color: Colors.deepOrangeAccent,
                ),
              ),
            ),
        
          ],
        ),
      ),
    );
  }

}

OutPut

Note: You customize this code into your project demand. We give some ideas, like:

1. You add one line to hide or show the ListView widget.

 showChildOpacityTransition: true,

2. you change the color code or _handelRefresh method and change the delay time.

3. You can also change the ListView static data to dynamic data from a database (mysql, firebase, etc.).

Conclusion:

Finally, by utilizing the RefreshIndicator widget to implement the pull-to-refresh Flutter capability, users may easily and naturally change the material that is presented. Here are the main things to keep in mind with Flutter’s pull-to-refresh feature:

1. Pull to refresh Flutter is a user interface pattern used in mobile apps to manually refresh the content displayed in a scrollable view.
2. Flutter provides the RefreshIndicator widget, which offers built-in functionality and visual indicators for implementing pull-to-refresh. but in this time we use liquid_pull_to_refresh to easy and reduce the time.
3. By wrapping a scrollable widget, such as ListView or GridView, with the RefreshIndicator, users can trigger a refresh action by pulling down on the screen.
4. During the refresh action, you can implement custom logic, such as fetching new data, updating the UI, or performing other tasks asynchronously.
