At SmartLogic, we began working with Flutter in Spring 2021, and we’ve been impressed with the benefits. Flutter app development allows us to create native applications for iOS and Android with consistency and efficiency.
Our team recently worked with WCK Direct, a platform that provides meals to households experiencing food insecurity. We were able to create a new iPad app with Flutter that helps restaurants manage orders, scaling the program to reach more people in more locations.
What is Flutter?
Flutter is an open-source UI toolkit that uses the Dart programming language, and the framework is reminiscent of React Native. As a framework, it enables developers to build Android, iOS, and web applications using a single codebase. This saves time and effort while maintaining consistency across different devices.
The compiler is a key feature that translates the Dart programming language in Flutter applications into native code for different platforms. Flutter web hot reload makes it easier for developers to see the changes in real time without restarting the application.
A significant difference between Flutter and other frameworks lies in its rendering approach. Instead of relying on the traditional Document Object Model (DOM) used by web applications, Flutter uses a widget tree. Widgets are the components of Flutter UI, which can be composed to create complex and custom user interfaces. This approach allows for more control over the appearance and behavior of the app, as well as better performance compared to DOM manipulation.

Is Flutter easy to learn?
In the season 10 premiere of the Elixir Wizards podcast, Sundi shares, "my overall thought about my experience with Flutter and working with a heavily type system would be impressed." Developers on our team with varying backgrounds and TypeScript experience echo this sentiment. Extensive, well-organized Flutter documentation allows developers to find the necessary information to troubleshoot and learn Flutter. The community is active, and developers contribute to online forums, create Flutter tutorials, and share experiences, offering plenty of resources for newbies.
Why Does SmartLogic enjoy using Flutter?
Types vs Dynamic
The Dart programming language is strongly typed, which means variables have a specific type, and the compiler can catch errors related to type mismatches at compile time. This provides better direction on errors and helps prevent bugs in the long run.
As Elixir enthusiasts, we see the different programming paradigms and use cases for both languages. Elixir has a different approach to state management than Flutter, using a functional programming approach instead of the reactive one used in Flutter.
Dart is best for cross-platform mobile and web application development with Flutter; Elixir excels in web development due to concurrency, fault tolerance, and code that is easier to reason about, test, and maintain. Choosing between Dart and Elixir depends on a project's specific needs and requirements. Being fluent in more languages helps us choose the best tool for the job and expand our understanding of what is possible and how it can be done.
Flutter integrates with Visual Studio Code and provides developers with useful features like autocomplete and in-editor debugging. The streamlined development environment is efficient, and the integration of null safety prevents runtime errors caused by null values.
Fastlane simplifies deployment to Android and iOS platforms. The streamlined approach helps developers save time and effort and keeps your app consistent across devices. For dependency management, Dart has its own package manager, pub, which is like Elixir's mix, making it easier to manage and update libraries and dependencies. The Flutter Github repository is active and allows developers to contribute and collaborate.
Styling in Flutter vastly differs from traditional web app development and doesn't rely on CSS for styling. Instead, Flutter uses widgets to define styles, which provides a flexible and unified design across platforms. Instead of using CSS properties, developers can use widgets like TextStyle for text formatting or the Flex widget for controlling layout and positioning. This approach takes some getting used to, especially for developers with a background in web development, but it ultimately enables more consistency.
Native mobile development often has styling conventions specific to the platform, such as Android's XML layouts or iOS's Interface Builder. In contrast, web development typically relies on CSS and HTML to create and style elements. This is where the implementation differences between Flutter and Phoenix become more pronounced. Flutter's widget-based approach to styling allows developers to build cross-platform applications with a consistent look and feel. Phoenix is a web-focused framework that uses traditional CSS and HTML-based styling methods.
