A Comprehensive Guide to Flutter App Development

In this continuously evolving app development market, Cross-Platform development has become popular not only because it takes less time but also eases efforts while developing an application. After cross-platform development comes into the limelight, several tools have been introduced to make development easier. In 2021, cross-platform development is the hottest topic among the top cross-platform mobile app development companies all over the world. The capability to develop native applications for Android and iOS platforms from a single codebase is gaining in demand, as it allows the flutter app developers to create the mobile apps in record time. 

Are you into app development or wondering how to build a mobile application for your business? If yes, then you must have come across one handy technology named Flutter. The tech world is growing rapidly with the rise and fall of technologies. Therefore, to build high-performing applications and improve time consumption on development, Google introduced Flutter to the app development world. Google announced in Flutter Spring 2020 Update, that over half a million developers use Flutter language every month. The spring update also reveals that Flutter app development is seeing an uptick in not just consumer apps but also enterprise development solutions.

Nowadays, numerous development companies have been using Flutter web development to create interactive, effective, and graphics-rich web applications. React Native development has become somewhat of a standard for developing cross-platform apps but Flutter’s treading right behind, to become the next need-to-know mobile development technology in 2022. Since it is a cross-platform framework and the topmost competitor of React Native, Flutter Vs React Native is certainly a hot topic among the developers. 

Let’s move ahead and understand everything about the Flutter app development and find out what is Flutter exactly.

What is Flutter Development Framework? {Brief Introduction}

What is Flutter Framework?

If you are wondering what Flutter is exactly, what all benefits it consists of, how it is different from other cross-platform frameworks, here are all the answers to your questions. Flutter is an open-source UI software development kit released by Google which is used to build natively compiled applications across all devices like mobile, web, and desktop from a single codebase. Instead of writing individually different code for both IOS and Android platforms, thanks to flutter, you have to write a code for once and your application will appear perfect and will replicate the native experience exclusive to the platform. 

As a Flutter app developer, you can save plenty of time on writing code for mobile application, and as a business owner, you save time, effort, and money. It works on the Dart programming language and integrates Material Design and Cupertino widgets to build a stunning and effective UI which not only feels native but could act naturally on every platform, although you are using the single codebase.

It doesn’t matter, if you want to run your application on any devices like TVs, mobile, tablet etc., Flutter always has your back. Unlike other popular solutions, Flutter is not only a framework; it is a complete software development kit, which contains everything you will need to develop cross-platform applications. This includes a rendering engine, testing and integration APIs, ready-made widgets, and command-line tools.

Pros and Cons of Flutter App Development

Let’s take one step ahead and do a slightly more in-depth analysis of all the pros and cons of Flutter app development, as we have already talked about how it all began and how Google’s Flutter became an immensely valued app development framework. We’ll now discuss all the features that make Flutter developers happy and their jobs stress-free. We’ll also look into possible bottlenecks that fall under the ‘cons’ category but we hope this could soon be resolved.

#1 Hot Reload

The wonderful hot reload feature makes developing apps with Google’s Flutter a breeze. It’s the feature that has gathered the most excitement and compliments from Flutter developers all over. Remember the times when you had to reload the entire application to view the slightest of changes you made to the codebase? Well, you don’t have to do it anymore.

With Flutter, every change or modification you make to the code is reflected in the app in real-time. Hence, you can make changes on the go and test as many variations as you wish, seeing exactly how they affect the app right on your screen. So go on, with Flutter’s hot reload feature try all your new and innovative ideas, add new features, experiment with the code, and fix bugs on the go.

#2 Code Reusability

Writing code for building an iOS app and then writing another individual codebase all over again from scratch for the Android version of the same app is by far the major time-eater in native app development. It is as much work as building two apps, but in the end, you only get one.

Flutter’s code reusability allows the flutter developers to write just one codebase and use it on not only Android and iOS platforms but even on the web and desktop. This cuts the development time and lets you launch your app much faster.

#3 Higher Quality

With the help of the hot reload feature of Flutter app development, code irregularities, and bugs can be spotted in real-time, which allows the Flutter developers to fix them right there. This leads to spending less time testing the app and accelerating the time-to-launch. Also, fixing bugs in real-time leads to a much higher quality app that loads fast and performs better across multiple devices.

#4 Faster Apps and Better Design

Apps that load slowly are uninstalled fast by the users. If your app has been loading slowly and taking long to respond, you may already be losing customers and trailing way behind your competitors. Apps developed with Flutter are faster to load, which means your user will immerse in the experience quickly instead of waiting for it to load and wondering if they should just abandon it already.

Google’s Flutter uses the Skia Graphics Library which is a fast and advanced open-source library with a solid backend. It every time draws the UI again as a view changes, resulting in fast loading of apps as it delivers up to 60 frames per second. This results in a fast and smooth app experience that users love. Flutter’s custom widgets are a complete pleasure when it comes to rendering UI. This not only helps you create great visuals for your app but also manages to do this with incomparable ease and promptness.

#5 Ready-made widgets for fast UI coding

Widgets are one of the revolutionary things that help you to create a user interface utilizing these building blocks. Any object in Flutter is a widget, from a button to padding or even fonts. Widgets can be united to build layouts, and you can pick to use widgets on any level of customization, from present building blocks to the lowest level when you create your widgets with the same tools. Widgets available in Flutter are well organized in trees, which is handy for rendering, but may result in too much complication of the whole structure. The UI development and customization that usually takes a long time to finish in cross-platform development takes a minimum amount of time with Flutter app development tools.

#6 Mild Learning Curve

Another important reason why Google’s Flutter is gaining popularity among developers is the availability of detailed documentation and a large number of examples. And this is very essential for developers who want to learn a new platform or a set of tools. Flutter’s Dart programming language is the easiest thing to learn. Many developers with slight coding knowledge can build prototypes and apps with the flutter framework. The mobile app development experience will not weigh into flutter programming. 

And it is particularly important for experienced developers too, who already have an eye on flutter app development, as they can easily find errors in the language design or in the toolkit itself. Flutter app development is loved for its clear documentation and friendly community of developers, bringing together experts and novices who are ready to help and share the experience of their design models and development templates. A friendly atmosphere reigns here, facilitating the easy development of technologies by an extensive range of users.

Cons of choosing Cross-platform Flutter App Development
Cons of Flutter App Development

Yes, there are some cons we can put on this list, as Flutter language is not matured at the moment. However, cons in flutter app development aren’t exactly deal-breakers, they’re more like a list of possible enhancements we can expect in future updates as there is a lot of rooms to grow, expand, and get better.

#1 Large App Size

Flutter apps are inclined to be a little heavier in size so if you are considering developing a light app, Flutter app development could show a little hurdle in that path. Now for some cases, file sizes could be a significant issue and cause a developer to pick an alternative tool for the development. As we can see and find enough memory storage space on the phone and that does not occur everywhere in the world with most of the users. However, this file size offers you enhanced runtime and performance so it’s not easy to comprehend the audience you are appealing to.

#2 Lack of Third-Party Libraries

Third-party libraries and packages have an important impact on software development as it allows some significant features for developers. These third-party libraries are usually free, open-source, pre-tested, and easily accessible. However, since Flutter’s Dart programming language is new for mobile app development, it’s not easy to find such free packages and libraries as the tool is still in the growing phase and refining. It will take some time to create the necessary flutter app development tools, expand functionality and develop the community.

#3 iOS Issues

Since Flutter is developed by Google, developers are technically concerned about its implementation for iOS. There’s no doubt that building Android apps on Flutter is fast and pleasant as Google is directly intent on fixing bugs in the shortest amount of time. But what about iOS devices? For example, when you click pictures from Apple devices, the application erases all EXIF ​​data. As a result, the photo is displayed with the incorrect orientation, with no location, no date, and without the correct gamma. One of the biggest updates in the Flutter app development is a pixel-perfect iOS appearance. iPhone settings were created on the flutter framework to allow the Cupertino widgets. However, It’s still uncertain if updates will keep coming as fast as Android’s version when the product will finally leave the beta phase.

Is Flutter best for Web Development?

If you want a web application that works smoothly on any platform, written once, has a faster time-to-market, offers flawless UI at a lower cost, then flutter web development is ideal for your project. There are very few particular instances where you do not want to implement Flutter. 

On the contrary, if you need a 3D touch application, Flutter web development doesn’t entirely support that for now. You might find flutter just a bit monotonous if your application needs heavy contact with computer hardware like a camera or phone calls. Flutter web applications seem to be on the heavy side if you’d like a relatively smaller version of the app. Although developing an eCommerce store with flutter mobile and then porting it to the web could be impractical for anyone, there will still be areas where flutter could fit well, like:

  • You already have an application developed using flutter app development tools but want to offer a web app to users to do the same function.
  • You would like to create interactive and original pieces of content on the mobile app and do not want to waste time creating the same stuff on the web application again.
