Step-by-step Guide for Flutter Application Development

1. Since the launch of the stable version 1.0 in 2018, Flutter has started winning the hearts of developers worldwide. As an ambitious and robust mobile app development SDK by Google, Flutter enables developers to target both iOS and Android platforms at once with a single code. What makes Flutter more appealing is the fact that it can make apps compatible with Google’s upcoming Fuchsia operating system? These days, the mobile app market is leaning toward a powerful user experience-driven app development process. Here, one of the biggest obstacles remains its division in iOS and Android app development. Users of both these operating systems are scattered across the world. Therefore, entrepreneurs simply cannot avoid any of them while targeting a huge audience. If you skip any of these OS, the brand experience may suffer badly. Flutter app development is considered as a solution to meet this problem. Flutter app developers can build cross-platform apps by using it. This post provides a step-by-step guide to use Flutter for developing mobile apps. Hope this developer’s guide will shed more light on Flutter app development. Let’s start with the brief introduction of this wonderful framework.

2. Flutter- An Introduction Flutter is Google’s open-source UI toolkit to develop cross-platform apps using a single codebase. Developers can build seamlessly-performing native apps for iOS, Android, and web platforms with the help of Flutter. What makes Flutter different from other frameworks is the fact that it does not use JavaScript. Google’s Flutter platform keeps a single codebase for developing various apps. Key Benefits of using Flutter for Developing Mobile Apps Whenever you want to develop an app for two different operating systems iOS and Android, bringing the same end result becomes quite a task. One of the key reasons for bringing the desired outcome is Android is an open-ended OS whereas iOS is a close-ended OS. Another reason is Android apps are developed by using either Java or Kotlin and iOS apps are developed by using Swift language. UI performance, source code maturities, security tests, and functionalities are some of the challenges that developers have to face while developing the same app for different platforms. Flutter app development can resolve these issues with ease. Flutter apps are written in Dart, Google’s object-oriented programming language. Dart was selected by keeping four criteria in mind- Developer productivity, Object orientation, faster allocation, and high performance. Flutter is an easy-to-use and extremely powerful language for fresh and experienced app developers alike. This language can increase their productivity exponentially and the Flutter app developers can provide a powerful UI experience thanks to Flutter widgets.

What’s more, the Flutter framework

3. offers access to the open-source package as well as a free SDK. This SDK (Software Development Kit) includes many things under its hood like a powerful 2D engine, large widget library, react framework, and APIs to connect with other related SDKs. The mobile app development company that uses the Flutter framework for developing feature-rich mobile apps can come up with expressive UI experience in a shorter period of time. The flexibility of this framework saves the developer’s time and effort. Also, there is no need to hire two separate teams for iOS and Android app development. As a result, enterprises can get a seamlessly-performing Flutter app in a short time. Flutter enables developers to write code for front end and back end in parallel. Flutter facilitates developers to reduce every development aspect to widgets, animations, gestures, and rendering. Developers can use a button as a page and a page as a button. Another great feature is ‘Hot Reload’. It makes recompilation fast. It enables app developers to inject the source code files into the virtual machines. It results in reducing the time frame for any changes in the code. In a way, the developer’s time is saved and modification is done rapidly. Flutter has integration with Firebase and it supports multiple IDEs (Integrated Development Environments). Developers can use this integration within pre- existing native apps for both Android and iOS platforms and get control over UI components. As a result, Android and iOS apps can get different yet identical themes in agile app development. All you can get is a decent technical advantage over your peers through a seamlessly-performing Flutter app. Another advantage of Flutter is it has powerful APIs to integrate desired features. APIs like FoundationBuilder, FutureBuilder, GestureBuilder, and

4. AnimationBuilder can make the developer’s life easy and they can introduce necessary features by using these APIs. Once developers get familiarized with this customizable APIs, they can make Flutter apps with desired features easily. Flutter also provides a testing framework for the SDK (Software Development Kit) with the capability to cover every aspect. Another boon for the developers is a quality assurance with native feel when they develop apps. What’s more, Flutter keeps on coming with updates on a regular basis. Now, the integration of these updates will become easier than before with the quality assurance and testing framework. Altogether, it is fair to mention that the Flutter app development process is all set to provide a rich user experience similar to that of native apps. All you need to hire certified developers from a reputed mobile app development company to get the app that is compatible with Android, iOS, and even the upcoming Fuchsia platform. The Hummingbird project is also an ambitious project that will allow Flutter app developers to use the same code for mobile, desktop, and browser-based app. The project aims at providing a seamless experience to developers when they make a single app for different platforms. Developers can also find the entire project on GitHub as the Hummingbird project is an open-source project. The only issue here is 3D app development is not yet possible. However, developers can find the Skia 2D rendering engine very powerful and handy to develop advanced mobile apps. An API for 3D development may come in the distant future. Here we give a quick list of Flutter features and benefits that makes it a preferred choice for developers. Concluding Lines Flutter app development enables companies to get versatile solutions while resolving many common issues. Startups and SMEs can also tap into

5. opportunities with customized and feature-rich apps that can easily run on Apple and Android devices. On one hand, small companies count on Flutter for saving big on development time and cost, and on the other hand, large companies prefer Flutter because it can enable them to get rid of a decentralized team of developers. There is no exaggeration in mentioning that Flutter can be considered as a future of mobile app development.
