Flutter is an open-source mobile development framework created by Google and released to the open-source community in 2011.

It has rapidly gained popularity within the software development community, owing to its unique features and capabilities.

It stands out as a versatile tool, enabling developers to create natively compiled applications for cross-platforms, including Android, iOS, web, and even desktop, all from a single, unified codebase.

What distinguishes Flutter is its fast development cycle, an extensive library of customizable widgets, and its ability to deliver reactive user interfaces.

In this article, I will shed light on the Flutter programming language, the key concepts around it, and why you should consider using Flutter for your next project, I will also walk you through some best software development practices with Flutter.

Significance of Flutter in The World of App Development

Flutter has transformed the landscape of app development.

Its ability to streamline the creation of applications for different platforms by using a single codebase is a game-changer.

According to a report by Statista from 29k+ respondents in July 2022, it indicated that 46% of software developers worldwide use Flutter as their cross-platform mobile framework, making it the most popular option.

Other mind-blowing facts about Flutter as reported by Statista include:

  • About one-third of mobile developers use cross-platform frameworks like Flutter, while the rest use native tools.
  • Cross-platform mobile frameworks like Flutter allow developers to build apps for multiple platforms from a single codebase, reducing costs.
  • Flutter maximizes app reach by enabling developers to target both iOS and Android with one app.
  • In 2020, there were 24.5 million software developers globally, a number expected to grow as app and web development increases.
  • Mobile developers make an average annual salary of $41,600, lower than other software developer roles like engineering managers ($96,000 average).

Flutter has not only reduced development time but also improved the overall user experience.

Flutter’s prominence continues to grow, as it addresses the increasing demand for cross-platform development solutions.

Key Concepts in Flutter

In this section, we will take a look at some of the features that make Flutter stand out from other mobile development frameworks.

Dart is an open-source programming language backed by Google and it runs easily on the Google Cloud Platform.

It is a known fact that Dart is approximately two times faster than JavaScript, and is type-safe while being compiled with both AOT and JIT compilers, making Dart very scalable across projects, similar to JavaScript so it is easy to learn if you know JavaScript already, and used extensively for the Flutter mobile UI framework.

Introduction to Dart Programming

Flutter is powered by Dart programming language.

Dart plays a pivotal role in its development.

The design of Dart takes inspiration from familiar languages like Java, JavaScript, and C# while enforcing strong typing for improved reliability.

As a compiled language, Dart code must be explicitly built before it can execute.

The Dart compiler analyzes source code and produces optimized machine code for the target platform.

Dart supports common programming concepts like classes, interfaces, and functions.

Unlike some languages, Dart does not have built-in arrays but instead provides collections APIs that implement data structures like arrays generically.

Dart also supports optional typing for flexibility in design.

Advantages of Cross-Platform Development

Cross-platform development is a strategy that is rapidly gaining traction.

It involves creating applications that can run on multiple operating systems such as mobile, desktops, and even browsers.

This therefore reduces development efforts and costs.

Flutter is one such mobile development framework that seamlessly fits into this approach.

In our blog post titled “The Flutter Approach to Cross-Platform App Development: Does it Work?“, we reviewed this approach of cross-platform development and took a critical look into how Flutter does this.

Widgets and UI Components in Flutter

Widgets are the building blocks of user interfaces in Flutter.

Widgets represent everything you see on the screen, from simple text and buttons to complex layouts and animations.

Flutter provides a rich set of pre-built widgets that you can use to design your UI, and you can also create custom widgets to suit your specific needs.

There are two types of widgets; these are Stateless and Stateful:

  • Stateless widgets are immutable UI elements that do not change after being initialized.
    They represent static content like text, icons, and shapes.
    Stateless widgets are used when the UI does not need to update dynamically.
  • Stateful widgets can change their state over time and update the UI accordingly.
    They are used for interactive elements like forms, animations, and components that respond to user input events.
    Stateful widgets have a separate State class that manages their mutable state and rebuilds the widget when the state changes.

Flutter’s Architecture: How it Works

Flutter is a layered, extensible system. It exists as a collection of independent libraries, each of which is dependent on the underlying layer.

No layer has privileged access to the layer beneath it, and every component of the framework level is optional and replaceable.

Flutter has three main architectural layers:

If you want to dive deeper into Flutter’s architecture and understand how these layers work together, I’ve written a detailed article on that topic.

You can read it here: Flutter Architecture: What Is It & How Does It Work).

Platform-Specific Development

Flutter for Mobile Development

Mobile app development is one of the primary use cases for Flutter.

Flutter allows building native mobile apps for both iOS and Android from a single Dart codebase.

It provides platform-specific tools like Xcode integration for iOS and Android Studio for Android.

Flutter implements separate render layers for each platform to translate widgets into native UI elements.

This allows accessing native SDKs and APIs like camera, location, etc.

Flutter compiles ahead of time into native code for optimal performance on mobile.

Flutter for Web Development

Flutter can compile to web-standards compliant HTML, CSS, and JavaScript.

This allows publishing Flutter apps to the web without changes.

Flutter for the Web provides web-specific plugins like integration with browser history and deep linking.

The canvas renderer is optimized for building high-performance web experiences.

Flutter on the Web supports progressive web apps that work offline.

Flutter for Desktop Development

Flutter desktop support allows compiling Linux, macOS, and Windows applications from Dart code.

It provides access to native desktop features like menu bars, system trays, and dock integration.

Flutter desktop apps can be distributed through stores or as standalone executables.

The experimental desktop embedding is still maturing but shows promise for cross-platform desktop development.

Development and Best Practices

Best Practices to Streamline Flutter App Development

Adopting Flutter best practices like state management with Provider, reusable widget libraries, separating business logic from UI, and using design patterns like BLoC can streamline Flutter development.

Another recommended good practice is to consider adopting automated testing, and CI/CD (continuous integration/continuous delivery) to maintain quality, reduce cost, and reduce code defects.

Essential Tools for Flutter App Development

Key tools for Flutter app developers include IDEs like VS Code and Android Studio, emulators, Dart and Flutter extensions, Supernova, AppCenter, and Firebase.

These enhance productivity when building, testing, and deploying Flutter apps.

Using Flutter for MVP Development

Flutter’s hot reload, reusable widgets and full-featured SDKs allow quickly building MVPs to validate ideas before investing in a full production app.

Flutter Redux and BloC are good state management choices for MVPs.

You can explore in detail why Flutter is an excellent choice for MVP development.

Exploring the Pros and Cons of Flutter

While Flutter offers numerous advantages, it is essential to consider both the Pros and Cons of Flutter.

Pros include faster development, native performance, rich widgets, and full-featured SDKs.

Cons are limited browser support currently, smaller ecosystem vs native SDKs, and dependence on Dart language skills.

Flutter Packages and Plugins
