Best Practices For Flutter Application Development

Flutter ranks amongst top 10 programming languages to learn in 2024-25, acc. To Stack Overflow Survey.

Is Flutter a framework, a programming language, a technology, an SDK, a frontend or a backend, a tool – or all of these? Supported by Google, Flutter is an open-source framework used at frontend – to build an application’s user interface (UI) for IOS, Android, Web, Desktop, MacOS, Linux platforms.

Then you might ask – whether Flutter is only a frontend framework, a CSS framework, or a Java framework. It combines the nuances of all these. It is built with DART, Java, and C/C++ programming languages – which makes it very suitable for building high quality mobile applications for any purpose, quickly.

It is also called Google’s UI toolkit because it is used for building natively compiled applications for mobile, web, and desktop from a single codebase. It facilitates creating Material Design by making use of Material packages.

Flutter maps HTML/CSS code snippets, making use of DART coding language, using ahead-of-time (AOT) compilation, except on the web where the code is transpiled to JavaScript or WebAssembly.

Now Flutter is being used with Flutter Inspector, Visual Studio Code, Appetize, Codemagic, Firebase, Supabase, Supernova, and Vysor – used for customizing the app’s outlook, presentation, and overall well-being.

While there were speculations that Google is about to drop Flutter, big multinational companies are using it and Google has built a broader strategy around it. Flutter is an actively developed platform, empowering apps like Google Ads, Reflectly, Hamilton, eBay Motors, Xianyu by Alibaba, KlasterMe, Watermaniac, and Google Pay with significant community support. So if you are thinking about learning Java or Flutter, learn Java first, and then Flutter.

While Flutter is being used at the front end, Java is being used at the back end. It is a cost-effective way towards faster development.

Flutter is used for creating apps that are cost-effective and look and perform like native apps, while still streamlining the development process. It features quick development time and a hot-reloading feature, which lets developers see changes to their code in real-time. It is especially good for building feature-rich applications. Its SDK includes command tools, packages, and widgets that help developers achieve their goals.

What Should Be Done To Amplify Flutter’s Effect?

• Consider typography, color, responsive design, adaptiveness, and accessibility, use a color scheme for a unified design, and use interactive gestures to make the app more engaging.
• Manage user interface updates, data from APIs, and other data that the app needs to function. Create a pure build function to avoid unnecessary operations that can slow down the user interface.
• Use pre-made widgets, which are more efficient than controllers, views, and layouts. For example, use the SizedBox widget to control the spacing between widgets and avoid unnecessary nesting of Container widgets.
• Write tests for critical functionality, and use an automated set of tests to save time and effort. Understand layout widget types and properties to create functional user interfaces.
• Use DartPad, an open-source code editor tool, for experimenting with Dart language, customizing the user interface, and prototyping.
• Using operators to reduce lines of execution, using streams only when needed, using raw strings, using relative imports instead of absolute imports, using log instead of print, not explicitly initializing variables as null, and using the const keyword whenever possible.

Flutter app development companies are implementing AI to enhance decision-making, optimize marketing strategies, and predict demand, and user behavior. Some real-life applications of Flutter AI integration are Google Lens, Amazon Lex, and Vivafit, likewise.

This combination is especially useful for e-commerce platforms, Travel and Tourism, Fitness and Wellness Tracking, Food Delivery Services, Remote Work Solutions, Entertainment and Media Streaming, healthcare assistants, Smart retail solutions, Smart home automation, financial advisory services, education and learning platforms, and more.

Flutter app development services make it so easy to build visually appealing user interfaces that improve user experience. it makes use of Cupertino and Material design widgets to add native components for each platform. It is known for its high performance and ease of use, which makes it a good choice for building complex applications. Its rendering engine eliminates the need for a JavaScript bridge, which leads to fast and smooth animations. Flutter’s hot reload same time, as changes are reflected when the new build is being compiled. 

Flutter offers fewer native modules than other frameworks, which makes it harder to find solutions for certain features. Also Flutter apps are larger and bulky. They need to adapt to a unique UI development process.

Best Tips For Flutter App Development

Some new ways to prevent repetitive tasks, used by any Flutter app development company these days:

• Wrapping widgets manage layout complexities and modularize code, making it easier to maintain and debug.
• Searching for a file streamlines navigation and speeds up the development process by quickly locating specific files.
• Effective layout-building techniques ensure responsive user interfaces, enhancing the overall user experience.
• The spread operator simplifies the creation of complex data structures by allowing easy merging of lists and maps.
• Renaming Variables/Classes/Methods improves code readability by allowing seamless refactoring across the entire codebase.
• Adding dependencies facilitates the integration of third-party libraries and packages, extending the functionality of Flutter apps.
• Custom snippets accelerate coding by providing reusable templates for common tasks like boosting productivity.
• Extracting widgets promotes code reuse and clarity by breaking down complex UI components into smaller pieces.
• Const warnings optimize performance by encouraging the use of compile-time constants and reducing runtime overhead.
• GitHub Copilot assists in coding by providing AI-powered suggestions, which enhances productivity.

Released in 2017, Flutter has empowered more than 90,000 apps (updated in 2020, across all Play stores and app stores). The list of companies using Flutter/ apps, seems endless. But here are a few for reference: Hamilton, Reflectly, Dream11, BMW, Realtor.com, Google Ads, Reflectly

eBay Motors, Philips Hue, Dream11, Google Pay, New York Times, Toyota, Alibaba.com, Etsy, freeCodeCamp, pub.dev.
