海外TECH	DEV Community	The tale of Johnny Big Brain	https://dev.to/inhuofficial/the-tale-of-johnny-big-brain-48dm	The tale of Johnny Big BrainHi there dear viewer the year is and Johnny is sat crying into his bowl of oatmeal His boss has just given him an impossible task change every single list on the site to have less padding but don t change the padding anywhere else He had just spent the previous evening writing a regex to find all of his inline p classes on his lists but he realised the futility of trying to parse HTML with a Regex many before him had warned of this but Johnny didn t listen He threw his oatmeal in the bin dragged himself to the office and sat there staring at the screen in agony different lists across the site some statically implemented some generated via templates they all looked pretty similar but he just couldn t see a way to change the styling on all of them at once without breaking the padding on other items on the site Suddenly a woman he had never seen before popped her head over his monitor you all right there Johnny he started crying No he sobbed My boss wants this impossible task completing The woman smiled let me show you something she said softly sympathetic to Johnny s plight She showed him her departments website it looked very similar to his and was equally as complex Inspect that list right there she said Johnny did as he was instructed and he couldn t believe his eyes The HTML it was well there was more HTML than classes What is this witchcraft he asked her It is the way the internet was designed to work she exclaimed In the old days this is how we wrote websites Where can I learn this power he asked Not from a Jedi she replied Johnny looked confused he didn t get the reference The woman rolled her eyes and started to explain You see all of the lists on my site are defined in one place Johnny looked on in awe She showed him this thing called a Style Sheet See here she continued I have added CSS that defines the padding margin colour etc here Johnny s eyes widened as she changed one line of this magical language and pressed save She went through different pages across the site and the lists had different padding but nothing else had changed Where did you learn this skill he asked Oh it is the old ways the ways before The wind hysteria hit teach me Johnny exclaimed Johnny fidgeted as she explained feeling uncomfortable at the thought of this new way But how can I tell what styles are applied to an element if they aren t defined in utility classes within the HTML he asked She introduced him to the inspect element tool Amazing Johnny exclaimed But how can I make sure the team follows a design system surely this leads to confusion he exclaimed Great question she answered you write documentation to explain the classes This idea of writing documentation was new to Johnny but he quickly caught on to the idea Oh so if I want a card I design a card element for the whole site yes that is it she exclaimed And anyone can use that card element he asked excited by this concept Yes but you have to make sure your team know not to create their own version they need to know it exists otherwise confusion will follow So what you are saying is I should create a card component then document the component so others know how to use it Yes you are getting it now You see The wind happened because developers were too lazy to read and create documentation they were obsessed with the new and shiny things that promised a better life without effort they just couldn t see the mess they were creating at the time Notice how we have no build step notice how I can just grab this CSS file and put it onto this site and without any extra configuration it works Johnny finally saw it his HTML was legible and had few classes He could make changes in one place and update the whole site in seconds He could add a new widget in minutes document it and his team could then read about the widget apply the relevant class yes just one class and everything was displayed consistently and correctly across thousands of pages You have learned the old ways I must go now She wrote woman display none and vanished Johnny tried it johnny display none but it didn t work oh well maybe I just wasn t classy enough Johnny thought Johnny went to his boss with this new way of doing things His boss was amazed his boss told Johnny he should spread the news far and wide of his discovery It isn t my discovery Johnny exclaimed It was the lady from department B who taught me His boss turned white which scared Johnny as his boss was from Jamaica There is no department B his boss stuttered We got rid of it as their staff didn t work hours a week and we couldn t understand how they got things done still Johnny understood now the old ways had been forgotten because of laziness lack of understanding and the short sightedness of developers But it has now started to hurt developers If only people spent as much time documenting their CSS and learning CSS as they did evangelising about the latest shiny thing we wouldn t be in this mess Johnny thought But how could anyone have foreseen strange client requirements like changing one item on a specific element across a whole site How could anyone have foreseen any of this Johnny continued studying the old texts learning more and more about this simple and misunderstood language He then went on to teach of his findings His Ted Talks were legendary thousands of developers flocked to see this new way of doing things Johnny got paid thousands to show people his tricks that he had learned Johnny retired young and rich he was known as Johnny Big Brain He sat on his Yacht thinking about that mysterious woman who was the secret to his success He started thinking about the last time he saw her He wanted to see her he wanted to thank her for everything He grabbed his laptop taking all his knowledge he had acquired reading the old texts He started typing woman display fixed The endObviously this is just a silly jab at the tailwind hype train making people pick up bad practices Tailwind has its place and it is a useful read awesome tool for prototyping and side projects just step back from the hype for a minute every once in a while if you are building something bigger make sure you aren t painting yourself into a corner like Johnny did I encourage you to use Tailwind just don t use it exclusively in place of CSS without really thinking about it as I can see a few big gotchyas coming down the road that a lot of people are overlooking due to the hype utility classes for local adjustments proper classes for repeated items and you will be as happy as Johnny Big Brain in years to come	2021-04-22 06:22:42

海外TECH	DEV Community	Flutter - Most Trending Framework for Mobile Development	https://dev.to/gurshehzadsingh/flutter-most-trending-framework-for-mobile-development-1953	Flutter Most Trending Framework for Mobile DevelopmentWhen it comes to app development it can be difficult to find a compromise between quality and productivity either developers have to build the same application twice on both iOS and Android or they have to settle for a cross platform solution that makes it difficult to deliver the native experience that customers demand And here comes Flutter an SDK that is making headlines these days in the mobile development space Its creators say that Flutter offers a new path for mobile development focused foremost on native performance advanced visuals and dramatically improving developer velocity and productivity It has already been adopted by some of the most famous companies such as Alibaba Google Ads Birch Finance App Tree Hamilton Musical and many more So let s try to understand what Flutter is and what makes it so popular Flutter is an app SDK for building high performance high fidelity apps for iOS Android and web from a single codebase It enables developers to deliver high performance apps that feel natural on different platforms For example it is one of demo apps from the Flutter Gallery a collection of Flutter sample apps you can run right after installing Flutter and setting up your environment This app Shrine has high quality scrolling images interactive cards buttons dropdown lists and a shopping cart page Not bad But let s slice and dice it all So what is definitely good about Flutter Here are some points why Flutter might become the next big thing Building Android iOS apps at onceAs Flutter uses the same code base you do not need to write any individual code for both the platforms Ok but this is similar to any cross platform thing Next please Quick Performance and No Compatibility IssuesUnlike ReactNative NativeScript or Ionic Flutter doesn t require a JavaScript bridge to talk to OEM widgets Flutter works more like a gaming engine All the buttons text media stuff are being built inside Flutter s engine And this gives the application an additional performance boost And that sounds interesting High Speed Coding and Prototype developmentMake a change in the app and see them in the blink of an eye What can be better All thanks to Hot Reload If you re only changing the state of the existing app structure then you can see your changes in under one second by using Hot Reload If you changed the app structure by adding or removing individual components or even large sections of your app that takes a little longer… seconds under most conditions Great isn t it A Perfect Choice for Advanced UIFlutter renders all parts of the interface using internal graphics engine called Skia the same that is used in Google Chrome Mozilla Firefox and Sublime Text This fast and well optimized piece of software allows Flutter to behave differently than most of the other mobile development frameworks Cool DART LanguageFlutter uses Dart a client optimized programming language for apps on multiple platforms One of the greatest advantages here is that Dart code can be compiled in three different ways The first is truly native Ahead Of Time AOT compiled machine code executable that requires no interpretation And you can compile executables not only for Android and iOS but for Windows Mac and Linux too But of course you ll need to compile once for each individual platform since each uses a different kind of executable Second Dart can be Just in Time JIT compiled And here we have this “Hot Reload that was mentioned above Third Dart can be compiled in a way that results in JavaScript This allows Flutter to do something truly amazing It lets you put the same app you wrote for mobile and desktop into a web browser FuchsiaIt is an open source operating system currently being spearheaded by Google It uses a micro kernel called Zircon and is designed to be able to run everything from the simplest picture frame up through the most bleeding edge mobile devices Why is it mentioned here Simple Firstly Flutter drives the UI for the entire Fuchsia operating system Secondly this means you will be able to use Flutter to write apps for all kinds of IoT devices from refrigerators to alarm clocks and more More information about practical use of some of these things you could find in this article of an Android developer who is sharing his thoughts on Flutter after having rebuilt his app from Java to Dart Here I only mention the number of files code lines before the rebuilding for the app built on Java and after it for the app rebuilt on Dart As you see numbers speak for themselves Drawbacks As usual there are some things you should be ready for if going with Flutter Learning DART LanguageAs all the Flutter apps are written in Dart you should understand that there is no way to escape this language if you re considering Flutter to build your app on Still this reactive language looks familiar if you have worked with languages like Java or JavaScript And the experience with object oriented languages will be helpful as well Still you will definitely have to spend some time understanding all the syntactical sugar Everything in Flutter is a WidgetThe layouts are widgets the typography is a widget color is a widget button is a widget Even the app itself is a complete widget And this might take some time getting used to It is not intuitive for anyone getting started to think that “widgetly It might take you up to a month to get comfortable with Flutter Adding margins paddings and other attributes is not intuitive at first Also you ll need to spend some time understanding Box constraints However once you get there you ll see that it was totally worth the pain A bigger APK sizeDon t be surprised if you see your fresh out of the oven flutter app is bigger in size than its native counterpart by As the flutter made apps are used with built in widgets and not platform widgets their size seems to be usually large Currently the smallest possible app which can be made using Flutter can t weigh less than MB Flutter is not an operating systemThis means it does not have direct access to things like cameras Bluetooth GPS and other hardware So if your app communicates with any hardware via Bluetooth for example then you d have to develop these features separately for iOS and Android and integrate them into flutter afterwards In this case one of the major selling points of cross platform development i e time won t be much beneficial as you d end up spending time creating these features natively for both the apps Flutter does not have a very large support communityFlutter is still relatively new and does not have a community as large as other cross platform solutions such as React Native or pure native apps so it will need some time to grow the network of supporters So if you are someone who is afraid of documentation still cannot but mention that Flutter documentation is really good this point might become a drawback to you ConcludingSo as far as there s no other templating dialect for the time being that allows you to construct your UI by setting widgets Flutter looks very interesting indeed Of course it might initially seem difficult but later on it does reduce the amount of coding saves time and looks better all thanks to the power of widget support Flutter makes it easy to develop higher performing mobile applications This SDK further guides you with logic reactive development and composition Moving ahead this pays profits as your application becomes bigger Also the one should keep in mind the advantages of Dart language that can increase productivity in times You can release your app to six platforms while needing only one team to write the code Also think about what it would mean if you only had to worry about maintaining one code base instead of six Still you or your team will definitely spend some extra time to learn Dart However no matter what technology is used cross platform apps are still way behind native apps in terms of performance So if you have the budget to setup two different teams for iOS and Android we believe you should consider going native On the other hand with Flutter you will get your app faster and faster development saves you money what is good anyway and allows to validate your idea quicker So regardless of the number of individuals in your group or what your objective is
