    </What is Flutter?>

    Flutter is a free and open-source mobile UI framework created by Google and released in May 2017. In a few words, it allows you to create a native mobile application with only one codebase. This means a Flutter development company can use one programming language to create two different apps (for iOS and Android).

    Flutter consists of two important parts:

    • An SDK (Software Development Kit): A collection of tools that are going to help you develop your applications. This includes tools to compile your code into native machine code (code for iOS and Android).
    • A Framework (UI Library based on widgets): A collection of reusable UI elements (buttons, text inputs, sliders, and so on) that you can personalize for your own needs.

    To develop with Flutter, you will use a programming language called Dart. Google originally created Dart in October 2011, but they improved it a lot over these past years.

    What is the Dart programming language?

    Dart is an object-oriented, class-based programming language that Google developed. They introduced Dart 2011 and was originally aimed at replacing JavaScript as the dominant language for web development. While that initial goal wasn’t realized, Dart found significant adoption among Flutter development companies.

    Key Dart characteristics & features


    Dart provides support for asynchronous operations using Future and Stream objects. This makes it easier to write non-blocking code, especially useful for UI applications and I/O operations.

    Isolates for Parallelism

    Dart uses a unique approach to concurrency called isolates. Unlike threads, isolates don’t share memory, which eliminates potential issues with locks. Instead, they communicate by sending messages, ensuring that each isolate has its own heap memory, and avoiding shared state problems.

    Just-In-Time (JIT) Compilation

    Dart can be both interpreted and compiled to native machine code. JIT compilation allows for features like Flutter’s hot reload during development and ensures optimized performance in production environments.

    Rich Standard Library

    Dart has a comprehensive set of core libraries that provide functionalities for collections, math, async programming, and more.

    Familiar Syntax

    For developers coming from languages like Java or C#, Dart’s syntax will feel quite familiar, easing the learning curve.


    Dart uses an object-oriented approach with classes and objects, supporting interfaces, mixins, and abstract classes.


    Dart’s package manager, pub, offers a range of packages and libraries shared by the community. This ecosystem has grown, especially with the popularity of Flutter.

    Web Development

    Dart can be compiled to JavaScript using tools like dart2js, allowing Dart code to run in standard web browsers. The dart:html library provides APIs for DOM manipulation.

    Strongly Typed

    Dart is a statically typed language, which means that variable types are checked at compile-time. This can catch many errors before the code even runs.

    In summary, Dart’s early mission as a direct JavaScript competitor didn’t pan out as expected. However, its adoption as the language of choice for Flutter development companies has given it new life..

    What products are built using Flutter?

    Flutter, a popular open-source UI software development kit created by Google, has been used to develop a wide range of mobile applications across different categories due to its ability to compile to native code and its single codebase feature for both iOS and Android platforms. Here are some notable examples of mobile apps built using Flutter:

    Google Ads

    Google’s own advertising platform app, allowing users to manage ad campaigns from their mobile devices.

    Alibaba (Xianyu by Alibaba)

    The world’s largest online and mobile commerce company uses Flutter to power parts of its app, enhancing the user experience with smooth and engaging interfaces.


    A personal journaling and mindfulness app that uses artificial intelligence to help users navigate life’s complexities, built with Flutter to provide a seamless and visually rich user experience.

    Birch Finance

    Helps users manage and optimize their credit card use, taking advantage of Flutter’s capabilities to create a clean, accessible UI.

    Hamilton Musical

    The official app for the Broadway hit musical, offering fans lottery entry, merchandise, and exclusive content. Flutter was chosen for its performance and design flexibility.

    Coach Yourself

    A personal coaching and mental health app that leverages Flutter’s framework to provide a user-friendly and engaging experience.


    Tracks cryptocurrency prices and portfolio values in real time, utilizing Flutter for its cross-platform efficiency and smooth performance.


    Social media management tool for small businesses, allowing them to manage multiple social media accounts in one app. Flutter enables a unified and streamlined user interface.

    When is Flutter a good choice for a mobile app?

    There are various scenarios where it might be an excellent choice for mobile app development:

    Cross-Platform Development

    Develop once for both Android and iOS, saving time and resources.

    UI Consistency Across Platforms

    Ensure consistent branding and user experience across all devices.

    Fast Iteration

    Benefit from the hot reload feature for quicker development cycles.

    Advanced Animations

    Easily create detailed and smooth animations.


    More affordable than developing separate apps for each platform.

    Customizable Design

    Tailor unique user interfaces with its flexible widget system.


    Extend your app to web and desktop with Flutter’s growing support.

    Dart Advantage

    Leverage the simplicity of Dart, ideal for quick learning or existing knowledge.

    However, there are situations where Flutter might not be the best choice:

    Deep Platform-Specific Integrations

    If your app requires deep integration with platform-specific APIs, or if you need to use a particular SDK that doesn’t have a Flutter package, native development might be more straightforward.

    Very Complex Apps

    For extremely complex apps, like 3D games or apps requiring advanced graphics, specialized frameworks or native development might be more suitable.

    Mature Existing Native Apps

    If you have a mature app already developed natively for Android or iOS, it might not make sense to switch to Flutter unless there’s a compelling reason.

    Size of the App

    Flutter apps can be larger in size compared to native apps, especially for very simple applications. This is due to the inclusion of the Flutter engine.

    Our Flutter Mobile App Development Capabilities

    At CodeStringers, we offer a comprehensive suite of Flutter development services designed to empower your business with the latest in hybrid mobile application development technology. Our team of skilled Flutter developers is committed to delivering high-performance, scalable, and cutting-edge solutions tailored to your specific needs.

    Custom Software Development

    Cross-Platform Mobile App Development

    Build beautiful mobile applications in Flutter to reduce the effort of development and maintenance on multiple mobile device platforms. Developing with Flutter to support iOS and Android devices can save a third or more of the development effort using native technologies (Swift, Java, Kotlin).

    UX / I Design

    Building cross-platform mobile applications requires interfaces that support portrait and landscape layouts on phones and tablets where there are hundreds of screen resolutions creating obvious design challenges. Moreover, the choice must be made of whether to adhere to mobile platform provider (Apple, Google) UI design conventions or design a custom experience aligned to your brand that presents the same experience on all devices.
