Updated on May 15th, 2021

Mobile apps are everywhere in our lives. The impact is so profound that it stands as the most engaging way for businesses to reach their target market. But mobile app development is not an easy road. Not only do you need to develop the mobile app, but also make sure that you satisfy the customers. Who would love the loss, anyway?

Probably that’s why the enterprises are continually taking up cross-platform app development. Thanks to its ability to deliver flawless apps cost-effectively while saving time. While there are multiple tools and framework that facilitate cross-platform app development, Flutter (despite new) has proven itself on many terms. And hence, this article takes you on a journey to know cross-platform app development better, followed by analyzing how Flutter suits your idea the best.

So, let’s gets started!!!

What is Cross-platform App Development?

Cross-platform app development caters to the development of mobile apps that are compatible with multiple platforms. The best part is all this wrapped in a single codebase. Thus, it enables one to address various markets and target audience regardless of the platforms they prefer.

What are the Benefits of Cross-Platform App Development?

Cross-platform app development has a plethora of benefits to offer to enterprises. Here are the highlighted ones:

#1. Code Reusability

Code reusability is the most striking benefit of cross-platform app development. You can doe once and deploy it over multiple platforms. This not only reduces the coding efforts but also decreases the cost of developing a mobile app.

#2. Less Time to Market

The cross-platform app development framework leverages unified codebase that accelerates the development process. This, in turn, helps the enterprises to release the applications in lesser time.

#3. Cost-Effective

Leveraging single codebase for multiple platforms, this reduces the overall cost of development while making the process much cost-effective. Enterprises can get an app developed without huge investments on tools, resources, and technologies for each system/ platform. Besides, you do not need to hire a dedicated team for developing the mobile app for each platform.

#4. Easier Deployment

Most of the cross-platform app development frameworks offer the developers with tailor-made modules and extensions that they can integrate with other tools. This helps them to enhance the functionality and UI/ UX of the application. Also, frameworks make it easier for pushing the app updates across the devices and platforms as well as make the code easier to maintain and deploy.

#5. Uniformity

User experience is one of the essential aspects that determines the popularity of a software or an application. With cross-platform app development, you can use a single codebase for multiple platforms and thus ensure that the applications offer consistency and uniformity across them.

#6. Greater Reach

Cross-platform apps enable you to cover a broader spectrum of available platforms and devices. This increases your ability to address greater market potential and address the audience regardless of the device they are using.

Introduction to Flutter

What is Flutter

Flutter is Google’s Mobile App SDK that offers an extensive range of mobile app development tools. These tools comprise of framework, widgets, and tools. It enables mobile app developers to develop and deploy visually attractive mobile apps on Android and iOS platforms.

Flutter is a cross-platform app development framework that facilitates smoother and easier app development. Thus, you can build and deploy Android/ iOS apps using a single codebase.

Here is what sets Flutter apart from other cross-platform development frameworks:

  • It is a free and open-source cross-platform app development framework
  • Flutter is based on Dart which is a swift, object-oriented programming language.
  • It comes with its widgets well-aligned with its own high-performance rendering engine. Thus, Flutter apps are fast, customizable, and, intuitive.

You can either use innate UI elements or create a design on your own.

  • Flutter architecture is based on reactive programming.

What are the Benefits of Using Flutter for Mobile App Development?

Flutter has a to offer not only to the mobile app developers but to the app owners as well. One of the most significant benefits is its ability to enable cost-effective mobile app development and reduce time to market. Thanks to the in-built UI elements, it helps you deliver a flawless app interface with smooth animations. But that’s not just it. Let’s explore some other benefits of developing mobile apps with Flutter.

#1. Faster Mobile App Development

Mobile app developers worldwide favor Flutter for its ability to augment the speed of mobile app development. The changes once implemented on the code are seamlessly reflected on the mobile app in an instant. Also known as Hot reload, the feature helps mobile app development teams to add features, fix bugs, and experiment quickly in as less as millisecond duration.

The very feature of Flutter also helps the developer-designer duo to try new things with UI elements and have them reflected immediately. Thus, you can check the effects on the spot. With this, you can also ensure faster and more efficient testing process wherein you can suggest fixes and check them in real-time.

#2. Common Code for Two Platforms

With native app development, you need to write separate code for the respective platforms. Thus, in case you have to develop an app for iOS and Android, you will have to work independently with experts of the field. This approach heavily requires increased efforts and thus, considerable investments in terms of time and money.

However, this is not the case with apps developed in Flutter. Covering iOS and Android, Flutter allows you to develop apps for both without having to write a separate code. Thus, one single codebase defines the mobile app development for iOS as well as the Android.

#3. Less Testing Efforts

Instead of having a dedicated app for each platform, you now have a common app for all of them. Thus, now the testing teams do not have to test for each platform independently. They can run the tests once and automate the test cases for others. That said, in case there are certain features implemented for a specific platform, they need to be tested accordingly.

#4. High-Performance Apps

Flutter app development leads to high-performing apps that run flawlessly without hanging. Additionally, the apps do not undergo cuts while scrolling.

It is typically due to Dart programming. Instead of running methodology, Dart is complied Ahead of time (AOT) into native code for respective platforms. Thus, Flutter gets time to communicate with the platforms without going through the JavaScript bridge responsible for context switching.

#5. Highly-Appealing User Interface

Flutter offers a wide array of widgets that help you enhance the visual aspects of the mobile application. You can either make the best of these available widgets or customize them as per the requirements.

#6. Backward Compatibility

Flutter apps are capable of rendering the same look and feel not only on the latest devices but also on the older ones. The support to older devices comes absolutely free of cost. Thus, while developing the apps, you do not have to worry about the app’s performance on older devices.

#7. Flutter is Considered Perfect for MVP Development

MVP or lean product development is one of the most favored choices nowadays. This is basically due to its ability to help you test your idea in hot waters and implement changes as you go. Thanks to the benefits offered by Flutter, it is considered best for the MVP development.


What are the Cons of Using Flutter for Mobile App Development?

No doubt that Flutter has a lot of benefits. That said, just like any other technology, it does not scale high on specific parameters of mobile app development. Let’s explore some of them here:

#1. Libraries and Support

Google support for Flutter, undoubtedly offers an expansive set of libraries with functionalities ready to be implemented. However, not every feature is available as a library. And thus, developers need to build them for implementation when the need be.

#2. Flutter does Not Offer a Good Framework for following Mobile Applications

Flutter is great. But, it is not suitable for specific applications. These include:

#1. Progressive Web Apps and Instant Apps

Flutter apps are bigger in size, even in the most optimized form. The overhead ranges from few megabytes to 20MBs, depending if it is a release or development build. Thus, the reason that it is not best suited for the applications that need to be smaller in size. This includes progressive web apps and instant apps.

#2. Apps that Need to Interact with Hardware Frequently via Bluetooth

Similar features like BLE connections need to be implemented independently for the respective platforms. In case you still want to achieve the same, you will have to build them separately and integrate with the Flutter app.

#3. Apps the Need Rare, Less Popular Native Libraries

The rare and less popular native libraries are missing from the Flutter repository. Thus, if you need them during mobile app development, you can indeed make use of them.
