In recent years, Flutter has become the most popular cross-platform technology on Stack Overflow. Thanks to its single code base, it has been appealing for both developers and app owners. In this article, we will introduce to you Flutter, pros and cons of Flutter it in your software development. 

Pros and cons of Flutter: When to use it in your project?

1, What is Flutter?

Before exploring the pros and cons of Flutter, let’s find out some of the most basic information about it!

Flutter is an open source and free UI mobile framework released in May 2017 by Google to help developers build native-looking IOS and Android apps. What’s worth mentioning is that it enables you to develop a native mobile app using only one codebase. This means you can create two different apps using the same programming language and codebase (for Android and iOS).

The language is built by using a programming language called Dart. It was created in October 2011 by Google and has grown significantly over the years. Dart is a front-end programming language for developing mobile and web applications.

2, Pros and Cons of Flutter: Advantages

Here’s a list of some advantages of language that might encourage you to try Flutter:

– High productivity: As we mentioned above, Flutter is cross-platform, which means that you can build your IOS and Android on the same code base. When compared to other cross-platform technologies, Flutter provides a greater measurable gain in productivity. It has a clear performance and visualization advantage over its competitors, whereas achieving such superiority when developing native apps is unrealistic.

– Great performance: Flutter does not use OEM widgets, instead providing its own ready-made widgets that look native to either iOS (Cupertino) or Android apps (Material Design). This means there will be less mediated communication between the platform and the app. Compared to React Native apps which are written in JavaScript, they must use a bridge to communicate with the Platform in order to access OEM widgets. This has become a bottleneck of the Framework. In contrast, thanks to Flutter’s own widget, it allows them to be extensible, customizable and maintain a steady 60 FPS. 

– Simple and fast development: Hot reload is one of Flutter’s most lauded features which allow you to instantly see changes to the code on simulators, emulators and hardware. Hot Reload in Flutter allows developers to only send incremental changes to the running Dart VM rather than running the entire code after each change. This feature in Flutter allows you to experiment, build UIs, add features, and fix bugs quickly and easily

– Compatibility: Because widgets are part of the app rather than the platform, you are likely to encounter few or no compatibility issues across OS versions. As a result, you will spend less time on testing.

– Open-source: Flutter and Dart are both open-source and free to use which provide extensive documentation and community support to assist you with any problems you may encounter that you can find here. Flutter also has a huge collection of testing tools for widget, unit and integration testing. Flutter has a unique feature that allows us to build widget tests to test the UI and run them at unit test speed.

3, Pros and Cons of Flutter: Disadvantages

– Young technology: Because Flutter is a new cross-platform technology, many Flutter functions are still in alpha and beta testing and may not always work properly. Some functions are currently unavailable in the library. Flutter will require some time to develop the necessary tools, expand functionality, and grow the community. It will take time for Flutter to build the necessary tools, enhance functionality and grow the community.

– Enormous File Size: It cannot be denied that its apps are generally larger than native ones. For example, the Flutter app is 4 MB in size but it weighs 500Kb on other platforms. In order to reduce the code size, programmers normally use different tricks like: avoiding animations, reducing images and using the fewest packages and libraries possible.

– Weak support for iOS: Unlike Android, the majority of SDK functions on iOS do not work properly. For instance, when taking photographs on Apple devices, the application deletes all EXIF ​​data. As a result, the photo is presented in the incorrect orientation, without a location, date, or the proper gamma. Today, VoiceOver, Captioning, Guided Access and Audio Description are all unavailable on iOS.

4, When to use Flutter?

With the pros and cons of Flutter above, when should you use it in your project? Here are some of its application:

– When you need to build your app fast

Flutter enables you to create an application in a very short amount of time because it is not only a cross-platform SDK, but it also includes a builder tool and a variety of UI widgets. At the same time, it can be a good solution when developing an MVP. Perhaps, you may need it for your upcoming pitch or releasing it to your users for testing. 

– When you want a complex UI

Flutter is a great option for UI-heavy apps because it allows you to control every pixel that the user sees. It gives you control over every pixel displayed to the user and allows users to have a consistent user experience across different platforms and devices. Furthermore, your app will look the same on both newer and older devices. With this SDK, you can simply create complex, eye-catching UIs that won’t affect the app’s performance.

To sum it up, when it comes to selecting a tech stack for your project, there is never a clear answer, but knowing what options are available will make the decision much easier. While considering all the pros and cons of Flutter, we think the advantages still outweigh the drawbacks. These advantages can make all the difference when it comes to spending your money wisely and getting your product to market faster. However, if you’re still indecisive, you can always seek expert advice from our development team from AgileTech!
