Pros and Cons of Flutter App Development

15 Decemberb 2022

Mobile app development has seen a surge in innovation and efficiency with frameworks like Flutter. This Google-backed UI toolkit has gained popularity for its cross-platform capabilities, allowing developers to create applications for both iOS and Android using a single codebase. As with any technology, Flutter comes with its own set of advantages and drawbacks. In this article, we’ll explore the pros and cons of Flutter app development to help you make informed decisions for your next project.

What is flutter?

Flutter is an open-source UI toolkit developed by Google for building natively compiled applications for mobile, web, and desktop from a single codebase. Launched in 2018, Flutter has gained traction in the developer community due to its focus on providing a consistent and expressive framework for building modern applications.

What is Flutter used for?

Flutter is primarily used for cross-platform app development. It allows developers to write code once and deploy it on multiple platforms, eliminating the need for separate codebases for iOS and Android. Flutter is commonly used for developing:

  • Mobile Applications: Flutter particularly well-suited for building mobile applications, including both Android and iOS platforms. Its ability to deliver a native-like performance and appearance on both systems simplifies the development process.
  • Web Applications: Flutter has expanded its capabilities to include web development. Developers can use Flutter to build responsive and engaging web applications, providing a consistent user experience across devices.
  • Desktop Applications: With experimental support for desktop platforms like Windows, macOS, and Linux, Flutter is gradually making its way into desktop application development.

Resources for Flutter Development:

Before delving into the pros and cons, it’s crucial to understand the resources available for Flutter development. Google’s extensive documentation, a vibrant community, and a growing number of plugins contribute to Flutter’s robust ecosystem. These resources empower developers with the knowledge and tools needed to build high-quality applications efficiently.

Pros of Flutter App Development

Single Codebase

One of the biggest advantages of Flutter is its ability to use a single codebase for both iOS and Android platforms. This not only reduces development time but also minimizes the chances of inconsistencies across different platforms.

Hot Reload Feature

Flutter’s hot reload feature allows developers to instantly see the effects of code changes, making the development process quicker and more efficient. It promotes experimentation and fine-tuning of the app in real-time.

Rich Widget Library

Flutter offers a comprehensive set of customizable widgets, making it easier to create a visually appealing and responsive user interface. This rich widget library contributes to a smoother development experience.

High Performance

Flutter compiles to native ARM code, resulting in high performance that is comparable to natively developed applications. This is crucial for delivering a smooth user experience, especially in graphics-intensive applications.

Expressive UI

With Flutter, developers have the freedom to create expressive and flexible UI designs. This allows for a high degree of customization, enabling apps to stand out in terms of both aesthetics and functionality.

Strong Community Support

Flutter has a growing and active community of developers who contribute to its ecosystem. This means a wealth of resources, plugins, and third-party packages are available, making problem-solving and collaboration easier.

Cost-Effective Development

Since Flutter allows for the development of both iOS and Android apps from a single codebase, businesses can save on development costs and resources. This is particularly beneficial for startups and small to medium-sized enterprises.

Cons of Flutter App Development

Large App Size

Flutter apps tend to have a larger file size compared to native apps. This can be a concern for users, especially those with limited storage capacity on their devices.

Learning Curve

While Flutter’s Dart programming language is easy to grasp for many developers, there is still a learning curve involved. Teams familiar with other languages may take some time to adapt to Dart and Flutter’s architecture.

Limited Libraries

While the Flutter community is growing, it is not as extensive as some other frameworks. This can result in fewer third-party libraries and tools compared to more established frameworks.

Less Mature Than Competitors

Flutter is a relatively newer framework compared to some of its competitors. This means it may not have all the features and stability that more mature frameworks offer.

iOS App Quality

While Flutter excels in cross-platform development, some developers argue that the quality of the iOS app produced by Flutter might not match the native development experience offered by Apple’s Swift.

Integration Issues

In some cases, integrating Flutter into existing projects may pose challenges. Compatibility issues with certain native modules or libraries may require additional effort to resolve.

Limited TV Support

As of now, Flutter’s support for developing applications for smart TVs is limited. This could be a drawback for projects targeting a broader range of devices.


Flutter offers a powerful solution for cross-platform app development, but it’s essential to weigh the pros and cons based on the specific needs of your project. The decision to use Flutter should align with your development goals, timeline, and the complexity of the application you’re building.
