These widgets remain static, offering improved performance by reducing build time, enhancing reusability, and facilitating better testability for your Flutter app development.
3. Implement constant keywords in your code.
By incorporating the “const” keyword into your widgets, you will immediately notice its impact during the compilation phase. This optimization ensures that it does not affect runtime and significantly enhances performance, providing a seamless start for your application.
Utilizing the “const” keyword optimizes memory usage, positively impacting rendering and overall performance. Furthermore, it allows you to bypass the time and memory-consuming process of rebuilding widgets.
4. Determine if the code runs Async/Await.
Before compiling the code, deciding whether you want to run it asynchronously or synchronously is essential. It’s important to note that debugging async code can be challenging, which can impact testing and launch times. However, using async code can improve readability and execution, albeit potentially affecting the application’s long-term performance. Therefore, it’s crucial to identify where you plan to use async code and incorporate it thoughtfully.
5. Avoid using build
When building your Flutter app for production, using the release mode is crucial for optimizing the build process. Unlock the potential of your code with this mode, producing a faster and more efficient execution while minimizing memory usage. Consider using code splitting as a powerful way to boost performance. This technique entails breaking down your code into smaller, more manageable chunks that can be loaded on demand.
