Flutter is a booming software development kit (SDK) for cross-platform mobile Application creation presented by Google. It is a programming language that uses a single codebase to develop applications compatible with both Android and iOS devices. Flutter is based on the Dart programming language that supports Firebase APIs, advertisements, Android studio, and inline videos for developing high-performance mobile applications. It is more like an SDK for touchscreen apps that run smoothly on cross-platforms. If you have a great idea and want to go further with the development, then you can go for a guide to hire flutter developers to implement your notion. This blog post is an ultimate guide on Flutter application development. Continue reading.

Why Should Businesses Use Flutter for Mobile Application Development?

Flutter is a great alternative to other cross-platform application development frameworks. The framework fast-tracks app building, reduces app creation expenses, and helps in developing an app with appealing designs and animations. Let’s take a glance at reasons why you should elect Flutter for the development of applications that run smoothly on both Android and iOS devices.

• Apps support more than one platform.
• Cost-effectiveness.
• High-performance apps.
• Quicker time to market.
• Great user experience.
• Worldwide exposure.

The following Image illustrates the Flutter Framework statistics over React Native:

When Should Businesses Use Flutter for App Building?

Following are some scenarios where the Flutter framework is a great choice for application building.

• When a complex UI is Required: You can create complex and striking UIs with Flutter and can also maintain the rapidity of loading the app at the same time. So, if you want to build something that needs an outstanding interface, Flutter is a good way to go.
• When you need to develop an app rapidly: The UI framework of Flutter lets developers build a mobile application in less time as compared to other app-building platforms. Flutter is not only a cross-platform SDK, but it also comprises a builder tool and ample UI widgets. Hence, you can write and test code quickly.
• When you want to enhance app performance quickly: The framework does not use JavaScript bridge, hence, it is faster and performs better as compared to React Native. Apps developed using Flutter function well without any performance issues or lags. Flutter is a good platform if you want both good functionality and performance at the same time.

To be fruitful, your apps must be dynamic and easily modifiable to the varying requirements of the customers. Making improvements and updating the application is much faster in Flutter as compared to other technologies. Next, we will share some practical tips that will make the Flutter app development process easier. Continue reading.

Some tips to Speed up Flutter App Creation Process

1. Break the code into numerous small widgets: — Split the code into small widgets. This will help you evade forming a large widget with a hefty build function.

Note: When setState() is called, all the widgets will reconstruct, therefore evade calling the setState() high up in the hierarchy if the variation is needed to a small part of it.

1. Make use of Flutter snippet :— Flutter snippet makes it easy for developers to create an app that provides a great user experience. The developers can utilize the StreamBuilder and SingleChildScrollView widgets to create classes as well as methods quickly in Android Studio or VSCode.
2. Utilize Introduction Screen for a customizable experience: — Stay away from the hassle of designing an inimitable introduction screen. Instead of this, you can create an attractive introduction screen using the Introduction Screen feature at the time of the launcher. Developers can modify the screen later according to their needs for the project.
3. Make use of Slow animation for easy debugging :— It is crucial to check for minute specifics while designing or creating your Flutter animation. There are possibilities that the coder may miss out on a specific segment that can affect the animation of the final section. You can slow animation and check for any bugs. All you need to do is to Click on Flutter inspector and then choose slow animation for seamless implementation.
4. Use Singleton Design Pattern to reprocess the data :— It is a great decision to use the Singleton design pattern when you require to execute only a specific class instance that regulates the complete execution. It also permits developers to reuse the data that is crucial for further development.
5. Format code using dartfmt :— Developers are well aware of the problems that occur while editing commas in the existing code. However, dartfmt makes it easy to format the code and developers can add trailing commas without interrupting the entire flow of the code.
6. Make the best use of get.it: — Time and again, developers need to insert dependencies when needed in applications logic. It is good to discrete widgets from the direct dependencies as it lets developers easily test and debug the code. The function get.in permits coders to do the same.
7. Create a Custom Extension to mitigate Repetition: — Writing, removing, and rewriting the code over again is a boring and time-consuming task. However, with the Flutter framework, developers do not have to write the same code again. You can use similar HTML code through pages without repeating the same code several times. Flutter provides a Custom Extension method to diminish code-writing repetition during app development.
8. Use itemExtent in ListView for large lists: — When you have a long list and you want to make a long jump using scroll, the use of itemExtent is essential. Let’s assume you have a list containing 10 thousand elements. Clicking the button, you will jump to the last element.

Conclusion

Flutter is an inclusive SDK that comprises everything you require to develop cross-platform applications. A rendering engine, command-line tools, ready-made widgets, testing, and integration APIs, and more tools are included. In short, Flutter is a great framework in whatever it endows. The above tips to speed up the Flutter mobile application development process are like sugar in the tea. If you are looking for the shortest, and fastest way to develop an eye-catching app with flexible UI designs, then go with Flutter. You can hire companies offering flutter application development services.
