August 17, 2022

Here is the list of useful libraries and packages for the Flutter app development. These are the best Flutter libraries and packages according to their popularity.


As an open-source cross-platform framework, Google’s Flutter UI framework is being rapidly adopted by the app development community since it allows developers to create apps across multiple platforms from a single codebase. As a result of Flutter Packages, Flutter is now more appealing for developing easy-to-use and modular code for creating applications across Windows, iOS, Android, and Linux. The ingenuity of these packages has even won the praise of many developers since they no longer have to think about Developing From Scratch. Plugins and packages speed up development and expand functionalities. As a result, Flutter won the most searched Google query in April 2020 in a fierce battle against ReactNative and is expected to continue the trend in the future. We have compiled a list of top Flutter libraries and packages to provide remarkable support for Flutter app development.


Among all the Flutter packages, this package can be used to launch URLs in mobile apps via predefined schemas and many features. This is because it supports both iOS and Android operating systems. HTTP, email, and SMS are all accepted URL schemas. Adding url_launcher as a dependency to pubspec.yaml is necessary to use it.

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

final Uri _url = Uri.parse('');

void main() => runApp(
      const MaterialApp(
        home: Material(
          child: Center(
            child: ElevatedButton(
              onPressed: _launchUrl,
              child: Text('Show Flutter homepage'),

Future<void> _launchUrl() async {
  if (!await launchUrl(_url)) {
    throw 'Could not launch $_url';


fl_chart is a remarkable library that can be used to create pie, bar, and line charts among others. In addition, it offers a number of excellent methods for personalizing the look and feel of the graphs to develop data-driven apps that offer features such as visualizing, sorting, and analytics.

The package also lets developers analyze the businesses of companies they are working for effectively through asynchronous programming, thus enhancing users’ experience.

Here is how you utilize it:

import 'package:rxdart/rxdart.dart';

void main() {
  const konamiKeyCodes = <int>[

  final result = querySelector('#result')!;

      .map((event) => event.keyCode)
      .bufferCount(10, 1) // An extension method provided by rxdart
      .where((lastTenKeyCodes) => const IterableEquality<int>().equals(lastTenKeyCodes, konamiKeyCodes))
      .listen((_) => result.innerHtml = 'KONAMI!');
