Blog Summary:

It goes without saying that Flutter is the most appropriate framework for cross-platform app development. But, it may sometimes not work due to your specific project requirements. In this case, looking for the right Flutter alternatives can be a good option. Let’s explore here. 

Flutter is one of the most sought-after frameworks for cross-platform app development.

According to research by Statista, in 2022, 46% of software developers across the world use Flutter to create cross-platform apps.

Meanwhile, it’s also available with several disadvantages, which prompt developers to look for some Flutter alternatives. They can find a variety of cross-platform app development frameworks that are good alternatives to Flutter in terms of features and flexibility.

Let’s explore some of the top frameworks that allow developers to build cross-platform apps hassle-free. You can choose the right one based on your project requirements.

What is Flutter? 

Developed by Google, Flutter is one of the most popular software development toolkits that use Dart programming languages. It’s available with a range of pre-designed widgets that allow developers to craft user interfaces that are fully consistent and visually appealing.

Developers leverage this open-source UI software development toolkit to build apps for different devices such as laptops, mobile, or desktops. Apps developed with Flutter are natively compiled. It includes a hot reloading feature that allows developers to do coding work rapidly and also make necessary changes instantly.

It gained wide acceptance for its higher efficiency when it comes to creating cross-platform and also high-performing apps while providing a completely seamless user experience across multiple devices.

Flutter Features

Flutter boasts a wide range of features that make it a top choice among developers. Let’s have a look at some of the top features of this framework:

Hot Reload

One of the top-rated features of Flutter, Hot Reload lets developers visualize any code changes instantly, even without restarting the apps. It maximizes the overall speed of the Flutter development process by offering fast feedback, which makes it easy to experiment.   

Single Codebase

Flutter is available with a single codebase. It facilitates developers to write code once and run it on multiple platforms like iOS or Android. It streamlines the overall development process and reduces the effort needed to maintain a separate codebase for various platforms. 

Expressive UI

Expressive UI enables developers to craft a customizable and visually appealing user interface. The framework uses a wide range of pre-designed widgets that designers can combine to craft complex UIs hassle-free. 

Native Performance

The framework includes the ability to compile code directly to ARM code and can achieve native-like performance. It removes the necessity of bridging between devices and applications. It leads to quick execution times, a responsive user interface, and smooth animations.

Widget-Based Architecture

Widget-based architecture is known for its higher flexibility and composability. Be it structural elements or complex layouts, everything in Flutter is available with architecture. Flutter’s widget-based architecture brings the possibility of code reusability and also makes it easy to maintain and update apps with time.     

The Pain Points of Flutter

Indeed, Flutter has outstanding cross-platform development abilities and is also faced with various challenges. Let’s find out several challenges that developers most frequently face when using Flutter:

Learning Curve

As mentioned, Flutter uses the Dart programming language, which is new to many developers compared to other languages, including Kotlin or JavaScript. Therefore, the learning curve for Flutter is tough, especially for those who are beginners in mobile app development. 

Limited Native Modules

Flutter is packed with a wide range of widgets for creating user interface (UI), which may lack several native modules that are widely available in various platform-specific languages. Developers may face several challenges when integrating specific languages, including Swift or Java. 

Large App Size

Larger app sizes are one of the drawbacks of Flutter, especially when compared to native applications. It’s a significant concern, especially for many users with limited storage capability on devices or in several regions with slow internet connections. The larger app sizes also tend to impact the download and installation times. 

iOS App Store Approval

Submission of Flutter applications to the Apple App Store may, several times, be challenging, especially during the processing. Apple is known for its complex guidelines and also for deviating from native-like behaviors or issues that are directly related to performance, which may lead to rejection as well. 

Community Package Quality

The package ecosystem of Flutter is indeed extensive. Meanwhile, the quality of community-contributed packages tends to vary. Developers may need help with maintenance, documentation, or compatibility between packages.  

Customization Constraints

Flutter brings limited customization options. Developers find it quite tough when it comes to implementing some platform-specific design elements. It’s certainly stringent to balance uniformity with the need for several platform-specific aesthetics. 

Platform-Specific Bugs

Since Flutter is a cross-platform framework, it aims to minimize some platform-specific bugs. But it’s not capable of eliminating the bug directly. Apart from this, one may also encounter several issues, especially during updates or when using some particular features. Moreover, developers also need to have a thorough knowledge of underlying platforms.

10 Best Flutter Alternatives

While exploring information regarding Flutter, you may also be interested in knowing about its alternatives. Let’s check out several top alternatives of Flutter, which you can consider using for your project development. 

Best Flutter Alternatives

React Native

React Native is one of the popular alternatives for Flutter. It enables developers to use a single codebase on multiple platforms while developing apps. It follows the principles of learning once and writing from anywhere.
