What Makes Flutter an Excellent Option for Cross-Platform Projects?

Startups with a cross-platform project usually deal with financing issues on the go.

Not just that, they also tend to bring complexity to the code as it deals in multiple variations of them and not a unitary one.

The development process for a cross-platform project can be much more lucrative for both the client and the developers if they could facilitate the process by making it less tedious and more convenient. 

Google, in 2017, launched Flutter as an open-source mobile UI framework that bridged the gap between cross-platform complexity and a single codebase. In other words, developers were able to build incredible natively compiled applications for mobile, desktop, and web. 

This made the framework popular established it as one of the best frameworks to work on amongst the developers’ community.

Flutter had left its mark on the world of app development by allowing developers to build a single code once and use it infinitely across multiple platforms. 

In this article, we will deconstruct the framework that Flutter is by addressing its features and benefits in cross-platform development. However, let us first understand the need and plight that encircles cross-platform development.

Understanding Cross-Platform Development

Cross-platform development is an app strategy that allows the developer to create a single application that can function perfectly on different platforms.

Different platforms share the same source code of these apps. This implies that developers can have the same code for the same app to implement in both Android and iOS without re-coding them individually for different platforms.

The anticipated growth in the global cross-platform app development market indicates a projected market size of US$120 billion in 2023, surging to US$546.7 billion by 2033.

This projection reflects a noteworthy Compound Annual Growth Rate (CAGR) of 16.7% from 2023 to 2033.

This trajectory underscores the increasing significance of cross-platform development, with substantial market expansion expected over the next decade, driven by the demand for efficient and cost-effective solutions across diverse mobile platforms.

There are several challenges that traditional app development faces. Such challenges laid the groundwork and need for the existence of cross-platform development.

These challenges include:

• Native API integration- APIs are used to connect one piece of software to another. However, integrating APIs traditionally has always been toiling and labor-intensive.
• The traditional approaches extend this process as developers have to lay the foundation to communicate APIs for every variant of the app. 

• Code Reusability- The lack of reusable code in native app development affects the presentation layer which is the face of the app. Your app tends to become more scalable if you can reuse or repurpose the existing code with enhanced speed.
• Consequently, the same code can be reused instead of starting over with a new variation of the code. Native apps, however, lack such reusable code. 

• Performance- Implement app optimization for every device and operating system version. This builds functionality.
• Cross platform apps are intrinsically optimized for all operating system versions, devices, and platforms.

Flutter- An Overview

Flutter is a UI framework that was created to develop mobile apps of all kinds. It helps developers in building apps that require a single code base for multiple platforms such as iOS and Android.

It also helps developers in building high-performance and high-fidelity apps for iOS, Linux, Windows, Android, Mac, etc. Developers can build the UI using widgets that react to different commands variably. 

Flutter is expected to retain its position as the most lucrative segment.

The targeted market segment is poised for robust growth, projecting a Compound Annual Growth Rate (CAGR) of 16.6% from 2023 to 2033.

This forecast underscores Flutter’s sustained appeal and its potential dominance in the evolving mobile app development landscape.

Origin and Evolution

Flutter was first introduced in 2017 by Google as an open-source UI software kit. It has ever since went ahead and expanded its horizons to contain web browsers, Windows, macOS, and others  

The major checkpoints in the history of Flutter include the Flutter version 1.0 at Flutter Live ‘18 as well as the establishment of Flutter 2.0 with its enhanced web compatibility support at Google I/O ‘21.

Features

Some of the features that make Flutter so unique and a class apart from its other counterparts are:

Single Codebase

With the help of the Dart programming language, Flutter developers can program an app under a single codebase which is generally reused and repurposed for other platforms as well.

This allows developers to refrain from superfluous re-coding and utilizing the same code for all applications which saves both time and effort.

Hot Reload

This feature of Flutter allows the developers to view instantly the changes that they have made without the recompilation of the entire application.

It also makes room for swift iteration facilitating experimentation, bug fixing, and UI refurbishment. 

Access to Native Features

Flutter provides carte blanche access to native features along with their associated APIs of the specific platforms.

Such a feature also allows developers to utilize device-specific features like geolocation, camera, sensors, etc., improving the app’s functionality and user experience. 

Robust Ecosystem and Community

The community of Flutter comprises a vast array of developers, scholars, and students altogether who help each other out.

This delivers a rich amount of libraries, tools, and packages facilitating resource finding, tutorials, and solutions.

Key Reasons to Choose Flutter for Cross-Platform App Development

Now that you understand the characteristics of Flutter, it is time to execute those traits into the process and understand how they can help in developing cross-platform apps via Flutter. Some of the advantages include:

Cross-Platform Commodities

Anything that was not possible years ago regarding cross-platform apps is now possible via Flutter. It has become a favorite for many developers as it provides a single codebase that can be reused in multiple platforms functioning the same which sets it apart from the other frameworks. 

It also becomes cost-effective as it saves time and money for both the client and the developers. You can use this time to focus on other facets of the business instead of worrying about the coding and programming side of the business.  

Reusable UI and Business Logic

Since code sharing is easily accessible for the UI developers, it makes the toiling task of constructing a different UI for a specific device easier. This makes Flutter unique as it can share the code of the UI and the UI itself.

The general idea is to make the app look native on different platforms without complexity in the code and Flutter delivers on this. 

All Flutter demands is a canvas to draw onto as it facilitates the development process and eliminates the need for additional mapping layers. It also makes the rendering of UI convenient, expunging any issues about UI inconsistency in different platforms.

This also saves much time and effort without jeopardizing the quality of the final product.

Customizable UI Design

Flutter facilitates easy and convenient customization even for complex projects that otherwise might be herculean for native platforms to accomplish.
