Open-source has always played a significant role in a way software is written and distributed; it has made the software development an easy, fun, and more convenient approach. Google’s free and open-source mobile app SDK for crafting high-quality native interfaces on cross-platforms in a record time of 120 FPS is the best example of a reliable mobile UI framework that Google has introduced.

Google’s Flutter UI framework, being an open-source cross-platform, is quickly embraced by the mobile app community as it lets you create mobile, web, and desktop apps just in a single codebase. Flutter has a thriving community with programmers putting their best efforts to take Flutter further to achieve new heights of success.

Just like other libraries, plugins and packages help to reduce the development time and extend the language’s capabilities the same way it offers significant functionalities, things like image caching, HTTP calls, to save the development time with the right set of tools.

Here I have curated a list of top Flutter libraries, packages, tools, and plugins to provide remarkable support in the Flutter app development. After conducting in-detail research, I have picked out the best list of things to support Flutter app development.

Top 10 Useful Flutter Libraries in 2020.

#1 fl_chart

To my knowledge, there is nothing official for the graphics yet, and fl_chart is a fantastic library that supports pie charts, bar charts, line charts, etc. It also provides impressive packages and parameters to customize the looks and feel of the graphs to develop data-intensive apps with features like drawling graphics, filtering, and analytics.

#2 url_launcher

This Flutter package assists in launching URLs in mobile apps through predefined schemas and various functions as it supports both the operating system — iOS and Android. It is preferable when it comes to multiple URL schemas like HTTP, email and SMS.

Example

import 'package:flutter/material.dart'; import 'package:url_launcher/url_launcher.dart'; void main() { runApp(Scaffold( body: Center( child: RaisedButton( onPressed: _launchURL, child: Text('Show Flutter homepage'), ), ), )); } _launchURL() async { const url = 'https://flutter.dev'; if (await canLaunch(url)) { await launch(url); } else { throw 'Could not launch $url'; } }

Reference: Pub.dev

#3 GetIt

It is one of the most significant packages that can be used to architect your application for better performance. It is a simple Service Locator for Dart highly inspired by Splat. Get_It is used by many known applications built with Flutter, and at Bacancy Technology, we are using it with almost all the Flutter applications.

Most Common Usage:

To access service objects like REST API clients, databases
Access View/AppModels/Managers/BLoCs from Flutter Views

#4 rxdart

It’s a reactive functional programming library for Google Dart based on ReactiveX. Google Dart has come up with out-of-the-box Streams API to provide an alternative API to add RxDart functionality on top of it.

How to use RxDart

import 'package:rxdart/rxdart.dart'; void main() { const konamiKeyCodes = const[ KeyCode.UP, KeyCode.UP, KeyCode.DOWN, KeyCode.DOWN, KeyCode.LEFT, KeyCode.RIGHT, KeyCode.LEFT, KeyCode.RIGHT, KeyCode.B, KeyCode.A, ]; final result = querySelector('#result'); document.onKeyUp .map((event) => event.keyCode) .bufferCount(10, 1) // An extension method provided by rxdart .where((lastTenKeyCodes) => const IterableEquality().equals(lastTenKeyCodes, konamiKeyCodes)) .listen((_) => result.innerHtml = 'KONAMI!');

#5 package_info

This library works as a bridge to fetch the application version information on both iOS and Android.

Usage:

import 'package:package_info/package_info.dart'; PackageInfo packageInfo = await PackageInfo.fromPlatform(); String appName = packageInfo.appName; String packageName = packageInfo.packageName; String version = packageInfo.version; String buildNumber = packageInfo.buildNumber;

CachedNetworkImage is used to present the images from the web and keep them in cache. It can be also used with placeholder and error widgets.
