How to Develop Progressive Web Apps in Flutter – Step by Step Guide
Technology that allows web browsers to provide services as mobile apps have resulted in a Progressive Web Application. As with an installed mobile app, the PWA gives the same native experience to users. What does PWA stand for? A progressive web app (PWA) is a mobile app that runs in the device’s default browser. Once you’ve downloaded the PWA from the website, you’ll be able to use it in the same web browser you used to access the website. There are a variety of technologies accessible for creating a PWA. However, Flutter is recommended for creating a prominent and optimum PWA with the help of Flutter mobile app developer. For starters, how would you go about creating a Flutter PWA? You may join us on this journey to build and deploy a PWA using Flutter regularly. Requirements for the Computer System: Get the Flutter SDK for your platform and get started. Install Google Chrome on your computer for the time being, the only browser that can be used to debug web apps is Google Chrome. Flutter’s process for creating PWA Steps 1. Install Flutter for the Web Flutter Channel Master It won’t be immediate, but after some delay, proceed as follows. flutter doctor -v Since it will download the most recent version of the Dart software development kit, a significant amount of time will be needed. The following should be the outcome: [√] Flutter (Channel master, v1.13.1-pre.59, on Microsoft Windows [Version 10.0.18362.535], locale en-US) • Flutter version 1.13.1-pre.59 at C:flutter • Framework revision e58dc16d7b (11 days ago), 2021-12-06 18:21:52 -0800 • Engine revision e7b69ced2e • Dart version 2.7.0 (build 2.7.0-dev.2.1 a9c77229c2) flutter config –enable-web It will make web support possible. flutter devices The following is an example of the output it will provide: Chrome • chrome • web-javascript • Google Chrome 79.0.3945.79 Web Server • web-server • web-javascript • Flutter Tools 2. Create new project flutter create hello cd hello It will make a brand-new app called hello. Include web functionality in an existing application. Flutter create. “.” is essential since it will provide support for the already available app. 3. Run-on web flutter run -d chrome It will execute our Application using Chrome on the localhost. 4. Run-on IP Mac or Windows systems must be linked to the same Wi-Fi network to fulfil this requirement. On windows flutter run -d chrome –web-hostname= –web-port=80 IP of the windows flutter run -d chrome It will launch our Application on Chrome using the provided IP address and insert that IP address into a mobile browser. On Mac: flutter run -d chrome --web-hostname= IP of the mac 5. Build project flutter build web Within the build directory, it will create a folder with the name ” web ” (please check the picture below for more information). Look in the web folder; you’ll find the following files there. Kindly note that these files are automatically produced and will be generated each time we build the project for the web; thus, if you could please duplicate this file so that we can have a backup of it. 6. PWA CONFIGURATION 1. Generate manifest.json file The following files will be produced as a result: Please make a copy of the pictures folder and the manifest file, and place them within the web folder. 2. Edit index.html (from web folder) index.html file will look like this: <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>core</title> <link rel="manifest" href="manifest.json"> <link rel="apple-touch-icon" sizes="57x57" href="apple-icon-57x57.png"> <link rel="apple-touch-icon" sizes="60x60" href="apple-icon-60x60.png"> <link rel="apple-touch-icon" sizes="72x72" href="apple-icon-72x72.png"> <link rel="apple-touch-icon" sizes="76x76" href="apple-icon-76x76.png"> <link rel="apple-touch-icon" sizes="114x114" href="apple-icon-114x114.png"> <link rel="apple-touch-icon" sizes="120x120" href="apple-icon-120x120.png"> <link rel="apple-touch-icon" sizes="144x144" href="apple-icon-144x144.png"> <link rel="apple-touch-icon" sizes="152x152" href="apple-icon-152x152.png"> <link rel="apple-touch-icon" sizes="180x180" href="apple-icon-180x180.png"> <link rel="icon" type="image/png" sizes="192x192" href="android-icon-192x192.png"> <link rel="icon" type="image/png" sizes="32x32" href="favicon-32x32.png"> <link rel="icon" type="image/png" sizes="96x96" href="favicon-96x96.png"> <link rel="icon" type="image/png" sizes="16x16" href="favicon-16x16.png"> <meta name="msapplication-TileColor" content="#ffffff"> <meta name="msapplication-TileImage" content="/ms-icon-144x144.png"> <meta name="theme-color" content="#ffffff"> </head> <body> <script src="main.dart.js" type="application/javascript"></script> </body> </html> Our code for the PWA is now complete. Let’s make a live connection and put it to the test. 7. Make a PWA Application Deployment Using Surge. The Front-End Developers’ tool for publishing static web content is called Surge. It is the most effective method for programmers to use when publishing static web apps for use in production. Requirements: 1. To begin, check that you are using the most recent version of Node.js 2. After that, install Surge with the help of npm by executing the following command: npm i -g surge Using a Mac, you must remember to include the sudo command. sudo npm i -g surge Using this command will install Surge globally on your system, which means you can use it in any location. To get a live connection and deploy on Surge, use this command. Surge We need some of your time and will provide the results: Now enter the URL “” into the web browser, and it will work.

Bioprocess Containers Market Expected To Reach $9.6 Billion By 2026
According to a new market research report,  "Bioprocess Containers Market by Type(2D and 3D Bags, Accessories), Application(Process development, Upstream and Downstream Process), End User(Pharma & Biopharma Companies, CMOs & CROs, Academic & Research Institute), & Region – Global Forecast to 2026" The global bioprocess containers market is projected to grow from USD 2.9 billion in 2021 to USD 9.6 billion by 2026, at a CAGR of 26.3% during the forecast period.  Emerging countries and the patent expiry of biologics are expected to offer growth opportunities for players operating in the bioprocess containers market during the forecast period.  [216 Pages Report] The global bioprocess containers is projected to grow from USD 2.9 billion in 2021 to USD 9.6 billion by 2026, at a CAGR of 26.3% during the forecast period. Growth in the bioprocess containers market is mainly driven by factors such as the growing biologics market, affordability and sustainability of single-use bioprocess technologies, and rising biopharmaceutical R&D.  Since most of the leading COVID-19 vaccine programs are using novel approaches, including mRNA, DNA vaccine, and vectors, these platforms are largely built on single-use technology. Most of the pandemic-related new facilities are largely engaging single-use systems due to their flexibility combined with high speed and much lower capital investment compared to traditional stainless steel equipment.  Download PDF Brochure @ The growth of single-use technologies can be attributed to the growing need for better, cheaper, and faster biologics production. Active development of individualized biologics and personalized medicines, including patient-specific cellular & gene therapies and therapeutic vaccines, demands high sterility and is therefore manufactured using single-use equipment and consumables.  In recent years, more biologics having higher potency that require smaller production volumes, advancements in biosimilars targeting smaller markets, and ongoing improvements in production yields and efficiencies that create production operations at much smaller scales have increased the use of single-use technologies such as single-use bioprocess containers/bags as they are best suited for small volume productions.  Additionally, the Centre for Biologics Evaluation and Research’s (CBER) (2021-25) strategic plan involves various schemes for boosting the growth of the biologics market. With increasing growth in the biologics market, the number of bioprocess containers needed for R&D and biologics manufacturing is also expected to increase in the coming years.  According to a survey conducted by BioPlan Associates in 2018, 73.3% of respondents agreed that leachables and extractables are major concerns that may limit the use of bioprocessing in the near future. As single-use assembly products are made of processed plastic materials, they often face the problem of contamination from the container due to leachables.
How to Programmatically Scrolling to the End of a ListView in Flutter?
A ListView is a scrollable collection of widgets organized linearly in Flutter. Additionally, it is the scrolling widget that is used the most. So, we will examine what the ListView widget in Flutter is in this article. The ListView Widget in Flutter fulfils the necessary tasks by placing the elements inside it in the correct order according to the Flutter developer requirements. ListViews Widgets come in the following four types: ListView() ListView.builder() ListView.separated() ListView.custom() Learn more about the listview widget and its type for more details. In our code, we sometimes need to scroll the list view to the Top or bottom (programmatically). So, in this article, We will learn how to scroll down to the bottom of a ListView in Flutter. To manage our ListView, we will want a ScrollController. ScrollController _scrollController = ScrollController(); To jump listview from top to bottom, you can use the below snippet. onPressed: () async { SchedulerBinding.instance?.addPostFrameCallback((_) { _scrollController.animateTo( _scrollController.position.maxScrollExtent, duration: const Duration(milliseconds: 1), curve: Curves.fastOutSlowIn); }); }, To jump listview from bottom to Top, you can use the below snippet. onPressed: () async { SchedulerBinding.instance?.addPostFrameCallback((_) { _scrollController.animateTo( _scrollController.position.minScrollExtent, duration: const Duration(milliseconds: 1), curve: Curves.fastOutSlowIn); }); }, Let’s see a complete example of a scrolling list view of both sides. class MyHomePage extends StatefulWidget { const MyHomePage({Key? key}) : super(key: key); @override _MyHomePageState createState() => _MyHomePageState(); } class _MyHomePageState extends State<MyHomePage> { final ScrollController _scrollController = ScrollController(); @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('Coflutter'), ), body: Column( children: [ Row( mainAxisAlignment: MainAxisAlignment.spaceAround, children: [ ElevatedButton( child: const Text('To Top'), onPressed: () async { SchedulerBinding.instance?.addPostFrameCallback((_) { _scrollController.animateTo( _scrollController.position.minScrollExtent, duration: const Duration(milliseconds: 1), curve: Curves.fastOutSlowIn); }); }, ), ElevatedButton( child: const Text('To Bottom'), onPressed: () async { SchedulerBinding.instance?.addPostFrameCallback((_) { _scrollController.animateTo( _scrollController.position.maxScrollExtent, duration: const Duration(milliseconds: 1), curve: Curves.fastOutSlowIn); }); }, ), ], ), Expanded( child: ListView.builder( controller: _scrollController, itemCount: 100, itemBuilder: (BuildContext context, int index) { return Card( child: ListTile( title: Text("Index : $index"), ), ); }, ), ), const Divider(), ], )); } } Output: Conclusion: We have learned an exciting ListView feature in this article that you may have seen on multiple websites and blogs.

How to Detect a Click Outside a React Component?
Today we are going to see how you can detect a click outside of a React component. We will understand this topic by creating a custom React hook for it. For example, consider a case where you want a custom React hook for dropdown or dialog components that need to close when the user clicks outside of them. So, in this article, we’ll figure out the way to find out this outside click. Checkout the best way to use React hooks that would be helpful to meet the quality. We can use the contains API to see if a target node is contained within another node. That is, it will return true if the clicked component is within the component we are interested in and false otherwise. A React component is a JSX-based UI building unit self-contained, reusable, and separated. Web developers also use custom dropdowns to allow users to choose from a list of alternatives. As we have seen earlier the components like custom dropdown should be close while user clicks outside when it is open. To build an enterprise-level application or implement these solutions, you can easily consult or hire react developers from Detecting an outside click of a functional component Let’s make an HTML tooltip by using the InfoBox React functional component. When the user hits a button, the tooltip appears, and when the user clicks outside of the tooltip component, it disappears. We will try to detect click outside the React component for the solution of this question. To get started, we’ll construct a new React app. You can also use the code below to detect outside clicks in your existing React app. Example: import React, { useRef, useEffect } from "react"; import PropTypes from "prop-types"; function outSide(open) { useEffect(() => { function handleClickOutside(event) { if (open.current && !open.current.contains( { alert("Show alert Box!"); } } document.addEventListener("mousedown", handleClickOutside); return () => { document.removeEventListener("mousedown", handleClickOutside); }; }, [open]); } function outSideClick(props) { const wrapperRef = useRef(null); outSide(wrapperRef); return; {props.children} ; } outSideClick.propTypes = { children: PropTypes.element.isRequired }; export default outSideClick; Output <button>Click Outside</button> Click outside: UseRef: The useRef hook allows the functional component to create a direct reference to the DOM element. Syntax: UseRef: The useRef hook allows the functional component to create a direct reference to the DOM element. Syntax: The useRef returns a mutable ref object. This object has a property called .current. The refContainer.current property keeps track of the value. The current property of the returned object is used to access these values. UseEffect: React useEffect is a function that is executed for 3 different React component lifecycles which we will see below. 1. componentDidMount 2. componentDidUpdate 3. componentWillUnmount 1. componentDidMount: We started fixing fetch calls before the class Component and even inside the render() method when we made made our first React component. This had strange negative effects on the application, causing groan. 2. componentDidUpdate: This React lifecycle is called immediately after a prop or state change has occurred. It signifies we clicked inside our worried element if the element that triggered the mouse down event is either our concerned element or any element that is inside the concerned element. Example: DetectElement.js: Output Conclusion So far, we have seen that how you can detect a click outside the the React components using the custom React hook. Also, we have learned to utilize UseEffet hook and UseRef hook while detecting the outside click by user. Thank you for reading the article. Hope you enjoyed the Reading.
