<b>Top 10 Flutter Libraries And Plugins To Use In 2020</b>
Open-source has changed the manner in which software is written and distributed. It has played a significant role in making software development simple, fun and more approachable. Flutter is an open-source cross-platform mobile app development platform having a wide developer’s community that puts efforts to make it successful. Mobile application developer community grasped Flutter so rapidly that there are a lot of open-source packages for it in an extremely short timespan.Libraries and packages reduce the time required for development as developers don’t need to develop from scratch for trivial functionalities. Use of right packages eases the things like HTTP calls and image caching. Here we’ll see top 10 libraries and packages for <a href="https://solaceinfotech.com/blog/flutter-in-mobile-app-development/">flutter app development</a>. Top 10 Libraries For Flutter Development-1. GetIt-It is one of the most preferred and useful Flutter libraries that implements the service locator pattern and makes dependency injection breeze. Also it is necessary to follow a fixed pattern and also run through the same package frequently to make it unique, and the software does not get confused with file segregation.Most Common Usage:To access service objects like REST API clients, databasesAccess View/AppModels/Managers/BLoCs from Flutter Views2. rxdart-It is a reactive functional programming library for Google Dart based on ReactiveX. Google Dart has come up with amazing Streams API to provide alternative API to add ExDart functionality on top of it.How to use RxDart-<pre>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!'); </pre>3. URL Launcher-It helps to add plugin to every page. While building up a website or program there are some predefined schemas that perform various functions through it in a mobile software that is activated by ios and android too. These codes help to operate the page through a programming language. It is more useful when you want the OS to handle the URL for you. It supports multiple URL schemas like HTTP, mailto, SMS and so on.4. package_info-Package info plugin is used to fetch the data about the application’s version and other related things. This package is useful to check the app’s version at runtime and perform some tasks accordingly.Usage-<pre>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; </pre>5. Cached network image-This flutter library helps to save the image information in the cache when it is viewed on the Internet from your device. It is created to use with placeholder and error widgets. It comes with sane-defaults along with many customization options so that you can start to use it right away. It is highly recommended for building eCommerce and similar apps.How to use-The CachedNetworkImage can be used directly or through the ImageProvider. With a placeholder.<pre>CachedNetworkImage( imageUrl: "http://via.placeholder.com/350x150"' placeholder: (context, url) => CircularProgressIndicator(), errorWidget: (context, url, error) => Icon(Icons.error), ), </pre>6. LocalAuth-It provides ways to perform local and on-device authentication. These authentication methods refer to biometric authentication i.e. Touch ID APIs for iOS and fingerprint…

Interested in applying and learning Flutter for our university senior project. Torn between React Native and Flutter.
Our senior project group is interested in using either React Native or Flutter to create mobile applications. To provide background, we're all experienced Java developers; Python is another language we all have in common.A few group members don't feel comfortable with Swift, which is why we're looking for alternatives. We'll be collecting data from OpenCV/Tensor Flow using Python, storing the data on a database, and displaying the data on a mobile application.We're looking for a language that is easy to pick up and learn based on our prior coding background. Being able to easily create a friendly UI is what we're looking for.Is Flutter a good choice, or should we look at React Native?

Flutter team really need to fix on poor scrolling performance
It's mind boggling that simple things like scrolling through a listview becomes laggy and it doesnt feel native at all. I have an app on google playstore which I have migrated from native android. Some of my existing users are moving to competitor app because they cant stand the poor scrolling performance. It is not laggy but it doesnt feel smooth and native especially on 120hz screens.This happens when u have a variable height for each of your list item and you did not provide a fixed item extent. Its normal to have flexible height for each of your list item, apps like facebook and reddit has it depending on size of the content.This issue has been around ever since flutter was introduced on mobile and its even worse on the web now.Some examples of github issues raised on these:https://github.com/flutter/flutter/issues/52207https://github.com/flutter/flutter/issues/62796https://github.com/flutter/flutter/issues/51401
