What is Flutter precisely, and what makes it so attractive?

Flutter is a freely accessible software development kit (SDK) designed to simplify the creation of user interfaces (UI) for applications working on several operating systems. This technique of developing applications that can work on multiple platforms is commonly referred to as cross-platform development. By utilising the features of Flutter, developers can swiftly and easily generate applications that can be used on various devices and operating systems.

Flutter applications aid in cost reduction, as development groups do not need to produce different code bases for individual operating systems. Additionally, they benefit from a layered architecture that streamlines rendering and development processes, thereby boosting their effectiveness.

Developers treasure Flutter for its single codebase functionality, which enables prompt app deployment on multiple platforms. This function offers both economical and efficiency advantages, rendering it a top pick for numerous developers.

Advantages of Developing Apps with Flutter

  1. Unified codebase

    Developing apps using Flutter is simpler compared to native language development. Typically, creating an application requires proficiency in several programming languages like Swift, Java, and JavaScript, as well as a profound understanding of the complexities of app marketplaces. In contrast, Flutter developers only require fluency in the Dart language. This simplifies the app development process and makes it accessible to more individuals.

    Dart was developed by Google in response to the difficulties posed by JavaScript. This programming language provides several robust features associated with object-oriented programming. The release of the cross-platform Flutter mobile app development platform in 2017 further boosted its popularity. Additionally, as part of this launch, Google also introduced two of its signature products, Google Adwords and Google Fibre.
  2. Compatibility with all screen sizes

    Flutter offers developers a variety of fantastic features that enable them to generate applications for various platforms, including desktops, smartphones, tablets, and wearables, using a single code source. This saves developers time and resources while expanding the reach of their products.
  3. Flexible layout system

    Flutter is a powerful and adaptable framework for creating visually appealing user interfaces. Developers often encounter challenges when creating layouts that work for different screen sizes and aspect ratios while designing applications. However, Flutter provides an easy solution to this problem, offering an efficient and convenient way to design user-friendly applications.

    To ensure a consistent layout across all devices, Flutter utilises widgets such as rows, columns, stacks, and centres. These widgets enable the arrangement of items horizontally, vertically, and on top of each other, as well as the creation of padding, centre alignment, and margins.
  4. Hot reload capability

    Developing an app can be a time-consuming process, especially when it comes to running the app. For example, the entire process of writing the code, compiling it, and viewing the results on an iOS device can take 30 seconds. Thus, this aspect of app development is critical when allocating time to a project.

    When modifying the code and saving changes in Flutter, the user interface is instantly updated. Flutter’s user interface design is akin to having a website refresh button at your disposal. The hot reload feature lets you change the colour, style or button of the app seamlessly. Additionally, debugging, upgrading, and maintaining programs are conveniently located in one place with Flutter.
  5. Access to original source code

    Flutter is an open-source software development kit (SDK) that offers users great flexibility to customise their applications. After accessing the code, users can delve into the development team’s code and gain insight into how each widget operates.

    Unlike Apple’s iOS closed-source code, Flutter is an open-source software development kit that enables users to personalise individual designs or entire templates. With the ability to modify the code, users can, for instance, adjust the shape, hue, and size of a button.
  6. Accelerated time to market

    Flutter enables developers to create iOS and Android applications in a shorter amount of time than if they were to develop each application natively. Its user interface (UI) creation is not only user-friendly, but also highly flexible, making it an excellent option for those seeking an efficient and economical method to develop their apps. Additionally, its shared codebase allows for faster product delivery and significantly reduced time to market.
  7. Engine for high-performance rendering

    Flutter provides developers with a dynamic architecture that lets them explore widget possibilities. The Software Development Kit comes equipped with Skia, a high-performance multi-platform rendering engine that allows Flutter user interfaces to be executed on any device, such as mobile, tab, web, and desktop, without the need for modifications.

Flutter versus Other Frameworks

Flutter is a productive, user-friendly, and robust app development framework. However, for certain applications, there may be other native and cross-platform frameworks that are better suited. For example, React Native, Xamarin, and Ionic offer unique advantages and disadvantages that developers should assess when determining which platform to use for a given project.

Flutter vs. React Native

Developing apps with Flutter is faster since only one line of code is required. On the other hand, with React Native, each platform requires a separate set of code.

Flutter has a significant impact on the success of start-ups and small to medium-sized enterprises (SMEs). For new businesses to gain insight into their target audience and attract potential investors, it’s crucial to develop a Minimum Viable Product (MVP). Flutter’s unique User Interface (UI) and speedy reload features allow businesses to develop MVPs much faster.

Studies have shown that Flutter apps are faster than their React Native counterparts. This is mainly because React Native apps require the use of a bridge and native components, as well as optimisation that is specific to the platform, while Flutter does not need such processes.

To develop apps using Flutter, there’s no need to use external libraries since the Software Development Kit (SDK) comes with its own set of automation tools and deployment guidelines. In contrast, deploying React Native apps relies on the developer’s proficiency and the use of third-party tools.

Flutter vs. Xamarin

While Xamarin requires licence fees, Flutter does not.

Locating a Flutter developer is easier than finding a Xamarin developer due to Flutter’s extensive global developer community.

As Xamarin relies on third-party technologies and requires a large development team, it has been found to increase the time for conducting product tests. In contrast, Flutter offers a better and more cost-effective testing experience, requiring fewer resources.

While Xamarin requires a considerable amount of time to build and test products, Flutter is capable of quickly developing and testing complex projects.

Flutter vs. Angular

Although Google supports both Software Development Kits (SDKs), Flutter outperforms Angular in terms of performance. This is because Flutter uses the Dart programming language, which has been found to speed up development and improve user experience.

Moreover, while Angular employs only HTML to develop applications, Flutter utilises up-to-date web technologies like HTML5, CSS, Bootstrap, and JavaScript.

Why is Flutter app development attractive?

As per the 2021 developer survey, Flutter was the most commonly used cross-platform mobile framework globally, with 42 percent of developers using it. This indicates its significant popularity and high adoption rate among developers.

As per a 2020 Google report, the number of Flutter applications on the Google Play store increased from 50,000 to 90,000 by April 2020, indicating a growing trend of Flutter app development’s popularity. This surge in the number of apps is evidence of Flutter’s rising popularity as a mobile application development platform.

Flutter is an excellent framework for cross-platform application development, offering organisations an efficient and cost-effective solution to create apps with minimal risks and errors. Engaging Flutter developers can enable companies to reduce the time and effort required for developing an application, while also minimising the chances of inconsistencies in user interface and security.
