In the dynamic realm of mobile app development, iOS and Android stand as the dominant platforms, demanding distinct coding approaches. Cross-platform development has emerged as the solution to counter the complexity of dual coding.

The evolution from laborious double coding to streamlined app creation is now feasible through one-time coding via cross-platform frameworks. These frameworks facilitate the creation of apps compatible with various platforms like Android, iOS, and Windows. Favored for its developer-friendly tools and features, cross-platform development has gained traction.

Microsoft's Xamarin, Facebook's React Native, and Adobe's PhoneGap are notable products that each have their own benefits. Flutter emerges throughout this growth as proof of technology's constant advancement.

This blog will explore what makes the Flutter framework the most popular and preferred cross-platform SDK, highlighting its leading-edge capabilities and the value it brings to Flutter development services.

What is Flutter?

Flutter is, in a nutshell, Google's universal UI toolkit for creating stunning, natively built applications for every platform with a single codebase. Developers and businesses worldwide utilize the Dart language with Flutter to efficiently and swiftly deliver their minimum-viable products.

Flutter accomplishes this by using a library of pre-made widgets and various plugins, which streamlines and expedites the building of applications. Dart is used to implement the majority of the system.

What are Suitable Use Cases for Flutter?


As Flutter has gained prominence, the question about its ideal use cases has been circulating. Prior to committing to a Flutter mobile application, individuals seek to understand the realms of development it supports or doesn't. Flutter might not be the optimal choice if you intend to develop:

Instant or Progressive Web Apps: These applications necessitate small sizes, whereas Flutter-built apps tend to be larger than their native counterparts.

Apps requiring uncommon native libraries: Given Flutter's relative novelty, it doesn't encompass the complete array of native libraries in its repository. Thus, if an application demands an obscure native library, it can introduce complexities. Developers would then need to integrate custom-made platform channels, which inevitably consumes time.

Applications requiring communication with hardware via Bluetooth: While this functionality can be separately developed for both Android and iOS, integrating it into a Flutter app might be a time-intensive process.

Key Reasons Flutter is the Most Popular Cross-Platform SDK

Reason 1: Single Codebase

Do you know how software developers always wished they could write code once and use it on different devices? Well, that's what Flutter does! It's like magic – you write code in one place, and it works smoothly on lots of devices.

When we talk about Flutter apps, they're different from other apps because they don't need separate codes for things like Android and iOS. With Flutter, you can write one piece of code that fits many devices, with just a few tweaks here and there. This is super helpful for businesses, the folks who make apps, and the people who use them.

Using a single codebase saves businesses lots of time and money. They don't need different teams to work on each type of app anymore. Instead, one team can manage everything together, making the whole process much easier.

Reason 2: High-Performance

Recent researches highlight Flutter's impressive speed. It compiled over 90% faster for CPU-intensive tests on iOS and Android compared to other cross-platform frameworks and even native languages like Swift and Objective-C. Flutter excels in performance, even outpacing Swift in specific aspects.

Flutter's speed is attributed to:

  • Flutter's DevTools: These tools provide profiling, code coverage display, and performance overlay, which offers valuable statistics about frame rendering, aiming for a smooth 60 frames per second.
  • Skia: Flutter uses Google's Skia engine, a robust graphics library also powering products like Chrome and Android. It employs reactive programming, updating UI elements as state changes.
  • The Dart Language: Dart is optimized for fast apps. It employs Ahead of Time compiling, creating swift and almost native apps in Flutter without relying on a slow JavaScript bridge.

In essence, Flutter's blend of tools and technologies ensures remarkable speed and responsiveness, making it an excellent choice for efficient app development.

Reason 3: Hot Reload for Rapid Development

The speed of development can be a game-changer for the success of an application, and here's where Flutter shines with its 'Hot Reload' feature.

Hot Reload is a feature in the Flutter framework that allows developers to see the immediate results of code changes they make in their app's source code, without having to restart the entire app. It significantly speeds up the development process.

It not only speeds up the process of adding new things and fixing issues but also makes it easy for developers and designers to work together. With Hot Reload, they can collaborate and make improvements to the app in real time, seeing the effects right away. This back-and-forth helps them try out different ideas and experiment freely.

For example, if a developer is working on how the app looks and wants to try different layouts or colors, they can make the changes and immediately see how they play out in the app. And if a problem pops up, they can fix it and see if it works right then and there.

Reason 4: Built-in Widgets

Widgets are like the building blocks that give your app that extra 'wow' factor. And in the world of Flutter, Widgets are the star feature. They're like the creative tools that help you design a good-looking and super-responsive interface for your app.

These widgets are your secret sauce for making both the functional and good-looking parts of your app. Think of buttons, text boxes, and other things that people use to interact with your app. What's even cooler is that you can mix and match these pre-made widgets to come up with your very own special design for your project.

Reason 5: Ideal Choice for Testing MVPs

For startups, creating a Minimum Viable Product (MVP) is crucial to try out business ideas with real users. With Flutter, entrepreneurs can swiftly test their concepts in the actual market. Flutter's fast development process means you can see results sooner. Plus, developers get access to a bunch of helpful libraries, plugins, and connections to different APIs and tools.

Flutter streamlines adding features and functions to your MVP without too much hassle. This means entrepreneurs can see MVP outcomes in less time and with a smaller investment compared to traditional native development.

Reason 6: Supportive Community of Flutter Developers

In the world of Flutter, you're never alone. There's a bustling community of developers ready to assist when you're stuck or facing a challenge. With loads of online resources, forums, and tutorials, learning and problem-solving becomes a breeze.

With these important points in mind, it's evident why so many developers are embracing Flutter for their cross-platform app projects. It's a flexible, top-performing, and effective framework that empowers you to craft impressive apps for any platform.
