We are going to cover below points in this blog:


In the digital age where apps are the most preferred way to grow and promote the business, its development is also gearing the pace. Various technologies have been adopted to accommodate cross-platform mobile applications. One of the trending apps among all is Flutter.

Being a complete SDK – Software Development Kit, Flutter is an open-source and free technology developed by Google for creating Android and iOS apps with a single codebase.
It is based on Dart programming language and is equipped with a rendering engine, ready-made widgets, testing and integration APIs, and command-line tools.

Why Flutter?

– To save time and increase productivity and marketing
– To scale app across different platforms & OS
– To try and test new trending technologies for mobile app development

Advantages of Flutter

Faster Development

Flutter is a cross-platform solution, makes it easier for one codebase to run on both Android and iOS. This saves a lot of development time. You don’t need two teams working on the code for a single platform which in turn saves efforts and money. Thus, using flutter is quite economical and app development is speedier via it.

Hot Reload

This is a unique feature of flutter. Any changes that a developer does while developing will be instantly and easily seen in the app. This will simplify detecting bugs as the developer will be able to see the change on the go. This feature also aids the developer to experiment with new features and improvise the overall working of the app.

Better performance

The apps you create in Flutter are very smooth and seamless, i.e., they don’t hang or cut while scrolling, hence a better overall performance is guaranteed.

Instant updates

Flutter supports immediate updates on both the platforms – ios and android simultaneously. This enhances productivity and allows you to fix errors if any without restarting and with ease.

Advanced UI

Built with an incredible internal graphics engine, curating attractive & appealing custom UI elements is easy on Flutter and is supported on both Android and iOS platforms.

Easy to learn

Flutter supports Dart programming language. Ones who are not acquainted with the language or need to learn it for development can easily do so as Dart is easy to learn. Beginner developers can develop prototypes and apps with the framework. Moreover, one may find the necessary material like videos, docs, guides etc on the internet to make the learning procedure smooth and easy.

Disadvantages of Flutter

Development stage

Although flutter is gaining popularity, it is still in the development phase, it still has an immature framework. It lacks more advanced features that enhance the capabilities of various operating systems. One has to wait until it can support foldable screens or dark system mode, system compatibility remains a question too.

Programming language

Dart is not a fully developed language yet. Unlike Swift and Kotlin, flutter lacks in features or has less refined existing features which make it a cumbersome task for the developers.

Larger space occupancy

When we consider the size of the app, Flutter apps are quite large and “heavy” to start with. In terms of occupancy, they take a lot of space and take longer time to download or update itself.

No specifications/guidelines

As flutter is the newbie in the mobile application development arena, there are no specific “guidelines” regarding steps to develop Flutter mobile apps. This might prove to be problematic for developers when building more complex software.

Frequent changes

One of the drawbacks of flutter is that it’s framework and programming language undergo constant changes at times, making it tough to maintain the code for a longer period. There are even uncertainties regarding the future of flutter.
