Why do programmers love Flutter? Simply because Flutter is awesome. Flutter serves both business (lower cost) and application development (fast, stable and scalable development). That is why many large companies have moved to Flutter, such as Alibaba, Google Ads, Reflectly, eBay, and many more … Google has done a good job of building Flutter, and they continue to develop this framework even better.
Flutter Features You may already know a little about Flutter:
Flutter is an open source Multi-Platform Tool written in a separate Dart language, with its own image toolkit (Skia). Currently Flutter officially supports: Android, iOS, web (beta), macOS (beta), Window (beta), Linux. Nearly all popular platforms today The ability to create powerful UI. UI elements are supported by Google’s Material Design team. What is Flutter special about? Flutter is a combination of native-app with the flexibility to develop cross-platform applications
Flutter combines the quality of native apps with the flexibility of cross-platform development.
In fact, many other cross-platform tools can also be written for both iOS and Android, but have yet to create the same interface on both platforms.
But what Flutter actually does: Instead of writing on the platform’s native UI elements (like React Native and Xamarin), Flutter draws a “from scratch” interface (not based on native UI).
Flutter maintains a “native” experience and application feel, so you don’t need to worry about performance on any platform.
In addition, Flutter is open source, any developer can contribute to Flutter’s development on GitHub. And take a look at Flutter’s popularity – 96.1K GitHub stars, 13.3k forks, and 19,625 commits – you understand why programmers love Flutter so much.
How does Flutter work? Flutter does not directly translate into iOS or Android apps. The compiled application is a combination of the translation mechanism (built on C ++) and Flutter (built on Dart), all files are generated by compilation like this, for Each platform has a mechanism to create apps that are appropriate for that platform.
It is like game development: a game does not allocate its framework and functions are implemented with the game engine. The same goes for Flutter software – all Flutter SDK-based applications replace parts of the original framework with Flutter elements.
Although it may affect the size of the end application, the performance is still quite good – rendering is done at up to 120 FPS.
Due to the native compiler for ARM processors, simple rendering and an integrated set of tools and tools, Flutter makes the development process simpler.
In addition, it provides some very nice features like hot-reload.
Here is how it works:
When you click the hot-reload button, all code changes are displayed in utilities, emulators and emulators immediately. The application continues to work from where you were before the hot-reload: update the code, but execution continues.
Why choose Flutter for cross-platform applications?
The new Flutter versions will continue to debut with more advanced features on their sleeves. But there are plenty of advanced features that perfectly explain why Flutter is so popular.
First, cross-platform development with Flutter, contrary to popular belief, does not make the software worse.
Flutter comes with all original widgets for Android and iOS interfaces like Material Design and Cupertino. In addition, the framework can change the behavior of separate elements to create similar UX for app users.
Second, Flutter allows discrete compilation of files in dev mode. The JiT compiler speeds up software development and debugging.
Third, Flutter allows for a flexible and expandable backend.
It supports plugins like Firebase, SQLite, etc. (pub.dev will help you find the plugin you require). Firebase makes the application infrastructure scalable, requiring no servers and redundancy.
So if you’re working on applications that require real-time databases or cloud functions, Flutter will help you get back.
And the last thing: Flutter is easy to learn.
From the outset, Google developers have set a goal of lowering the barriers to entry. They carefully work out the documentation and can be used by resource developers. It even has special sections that you can use to start learning the framework depending on your expertise:
Flutter for Android developers Flutter for iOS developers Dynamic Flutter for React Native devs Dynamic Flutter for Xamarin.Forms devs Flutter for web developers Due to Flutter’s detailed documentation, you will find out how to code in Dart even if you only have experience with Unity graphics tools to create Android games.
Flutter 1.12 (Latest version) and its privileges
Let’s see Flutter introduce some of the cool features in its latest version 1.12:
Dark mode iOS
From now on, Flutter supports iOS 13 interface, including full dark mode support in Cupertino gadgets. And it’s not just about swapping the background but adjusting the remaining colors to match.
Another major improvement is the Add-to-App update, which integrates Flutter into existing iOS / Android applications.
The new version of Flutter supports adding a full-screen version of Flutter to the application, along with:
Stable API integration in Java, Kotlin, Objective-C and Swift Support using plugins in Flutter modules Additional integration mechanisms through Android AAR and iOS frameworks
Beta web support
The new Flutter master, dev and beta channels provide improved support for the web. Want some examples?
Here, Riv Rivet, an educational project used Flutter and Firebase to create a web version of their application.
The new version of Dart 2.7. This update enhances the operational experience with Dart 2.5 in the way security chains handle extended capabilities and processes. This helps developers prevent errors when variables have a value of 0 and analyze integers in a string.
And here are some other features of the latest Flutter version:
macOS (alpha) desktop support for multi-device debugging of yellow image testing Improving the Android build of DartPad Flutter update well, but not without issues: What keeps developers from using Flutter ?
Flutter is great: easy to start, simple to work with and presented by a major tech company. However, these are the reasons why your Senior Developer may not share your optimism.
Popular (low) is common
Unlike Java / Kotlin for Android or Swift / Objective-C for iOS, Dart does not have a high level of popularity. And it is very unlikely.
Dart is not too difficult to learn and has a lot of tutorials (like this one), but some developers are still attached to Java and other familiar tools.
At the same time, you cannot use Flutter and not use Dart: even the killer feature of Flutter -hot-reload- will not work without Dart.
Does not support all devices
You can’t create apps for 32-bit iOS devices like those older than iPhone 5s. The same goes for Windows desktops: you can’t run Flutter on your 32-bit laptop.
And Flutter developers have no plans to fix it because “this will involve a very significant workload”.
So if you want to encrypt using Flutter, you’ll have to own an x64 bit device or upgrade the device you use right now.
The number of libraries is limited
Although there are many Flutter libs like fl_chart (for drawing graphics in Flutter), path_provider (used to locate files on Android / iOS), flutter_sliding_tutorial and more, the number is still limited.
This is not difficult to explain: Flutter is a relatively new framework and the developers did not have enough time to develop as many libs as the native language provided.
However, the most important libraries are available and new libraries will appear at all times.
Vibration applications are larger in size
… compared to specially developed applications. Flutter’s team measured the minimum application size (without Material Components, only a single Central utility, built with the shake -split-per-abi build apk), wrapped and compressed , is 4.3 MB for ARM and 4.6 MB for ARM 64.
The basic application is now ~ 4 MB in Android and ~ 10 MB in iOS.
Less proven expertise
Flutter might be popular with developers, but big companies didn’t rush to stop creating native apps (or React Native) and switch to Flutter.
For most companies, the biggest problem is Flutter’s novelty. Dart is newer than Java or C # and Flutter itself is completely new.
Of course, there are many open source Flutter apps, including big ones like Google Ads or Hamilton (check out the full list here), but not too much.
And no one who wants to become an entirely new framework user just has to switch to native development a few months later.
But most importantly, Flutter is the way you go alone:
not having many best practices (at least on large scale projects) is always an opportunity for you to be the first to deal with this particular problem. Little hope someone will help you – you’ll have to step by step carefully and be ready to face the consequences Where to Use Flutter
First of all, it is better to use Flutter for MVP startups when you have limited time and usually have money to verify your business model.
A cheaper Flutter app *:
- Compared to the cost of two native application development teams less than 40% of the simple process you can spend more time working with the features of the application. By opting in to the Flutter project, you will reduce development hours. Developing vibration does not take much time than native. Here is an example. Let’s say you’ve created an Instagram-like app for these two platforms. IOS development will take about 700 hours, Android – also 700h.
With Flutter, you will cover both platforms and save time: 700h Android + 700h iOS compared to 700h Flutter.
You save tons of time you can spend on other things, like polishing features.
If you’re building apps for a limited time on a limited budget, Flutter is definitely worth a try.
It looks so good and with every new update, Google developers add more tools to cross-platform development.
Of course, this framework may seem unusual to C # and Java lovers, but that doesn’t mean it will force you out of your comfort zone. Mastering the small syntax differences, you will soon find that UI development is several times faster than native development.
And if you succeed and if Flutter follows, it can give you some exciting mobile development experiences and opportunities in the future.
