Things To Remember For Your Next Flutter Project! 

Flutter is a well-known and powerful SDK for cross platform app development. This technology works on Dart Programming Language, which develops apps for Android and iOS devices. If you have thought about developing a flutter app, well that’s a great decision. It is less time consuming, safe, requires one codebase, and more efficient. So, flutter app development solution is the right decision to opt. 

Before you start your next flutter project, make sure you keep a few things in mind. Well in this blog, we will tell you those things to remember for your next flutter project. These things you should notice earlier before you start the next flutter app development project. We hope this blog will help you to succeed in your next flutter app development project. 

Things To Remember For Next Flutter App Development Project 

Static Code Analysis 

Linter is a useful tool for identifying and highlighting errors, warnings, and style flaws in programming code, aiding in their prompt correction. When working with Flutter, implementing a linter is straightforward, and it helps maintain code cleanliness. 

While there are numerous code rules to choose from, using a pre-existing set that follows Dart Style Guide’s best practices, such as lint, flutter_lints, or very_good_analysis, is recommended. It is always possible to add or delete specific static analysis rules in the analysis_options.yaml file, regardless of which package is selected.

Use The Latest Version Of Flutter 

If you want to improve the performance of your next flutter app development project, then use the latest version of flutter programming language.Flutter is constantly improving its features, performance, and fixes bugs. 

If you will stay updated with the latest version of flutter, that’s going to improve the performance at its most feasible level of flutter app development solutions. 

Reduction In Widget Rebuilds 

Flutter offers the benefit of effortlessly developing intricate user interfaces, yet this feature may affect performance. To optimise the performance of your Flutter application, reducing the number of widget rebuilds during the rendering process can be helpful. 

To do so, you can utilise the shouldRebuild method to evaluate if a widget requires a rebuild or not. By examining the present and past states of a widget, this method enables you to only rebuild it if required.

Usage of Const Keyword

Flutter provides the option of using the const keyword to establish compile-time constants for different app elements, such as data models, strings, and widgets. The usage of const can enhance the overall performance of your Flutter application in multiple ways. 

If you create a widget with the const keyword, it informs Flutter that the widget’s children and properties will not be altered during its lifespan. This enables Flutter to optimise the rendering and layout of the widget, as it can assume that there won’t be any changes in the widget’s properties and therefore, won’t need to check for them. 

Image Loading Optimization 

Images play a significant role in the functionality of various web and mobile applications, however, if not managed efficiently, they can lead to performance problems. To enhance the performance of your Flutter application, it is recommended to optimise the loading process of images. 

The CachedNetworkImage package can be utilised for this purpose, as it reduces the number of network requests by caching the images. Furthermore, the fade-in image technique can be employed to enhance the perceived performance of your application. This technique displays a low-resolution image initially, followed by a gradual replacement with a high-resolution version.

Use State Management Library 

Efficient state management is a crucial element for developing high-performing Flutter applications. Utilising a state management library enables you to consolidate your app’s state and minimise the need for numerous UI updates. 

Popular state management libraries for Flutter, such as Provider, Redux, and Bloc, offer distinct benefits and drawbacks. It’s essential to select the library that best aligns with your application’s requirements.

Optimise The Building Process 

The build process is another crucial factor that influences the performance of your Flutter application. To enhance the build process, it’s recommended to use the release mode while building the app for production. 

This mode generates an optimised version of the code, which runs faster and uses less memory. Additionally, you can employ code splitting to decrease the app’s size and improve its performance. This technique involves dividing the code into smaller and more manageable sections, which can be loaded as required.

Animation Optimization 

Incorporating animations can greatly enhance the visual appeal of your Flutter application, but if not optimised effectively, they can also result in performance issues. To enhance the animation performance of your app, it is advisable to utilise the AnimatedBuilder widget instead of the AnimatedWidget widget. 

The AnimatedBuilder widget enables you to separate the animation logic from the widget itself, thereby decreasing the number of UI updates needed. Moreover, the Tween animation can be used instead of the Curve animation to further optimise the animation. The Tween animation enables you to define the starting and ending values of the animation, whereas the Curve animation determines the rate at which the animation progresses.

Use Performance Analysis Tools 

If you will use a performance analysis tool, this is going to improve the performance of flutter apps. These analytic tools allow us to find bottlenecks and loopholes in the code and do optimization for optimal performance. 

In the flutter app development process, there are multiple built-in performance analytic tools such as Flutter Performance Tabs and Dar Observatory in the DevTools. These tools will help to monitor the performance of your flutter app in real-time and identify several issues. 

Conclusion

Optimising your flutter app is very important. If you want to perform better in your upcoming flutter app project, then make sure you follow all the above demonstrations. By following all the above mentioned things, you will be able to succeed with your flutter app with better performance. Identify and address the loopholes and rectify them with this high performing flutter app. Follow these techniques and tools and create a fast and responsive flutter app to achieve your targeted business goals.
