Flutter App Development Best Practices to follow in 2023

Flutter was released in 2017, and since then, it has gained immense popularity among app developers. It has been seen that renowned applications were built on Flutter, starting from the Xianyu app to Hamilton music to, finally, a top-notch eCommerce site, Alibaba.

Now, the question is, as the New Year is almost knocking at the door, do we keep using Flutter to get similar performance and speed? Also, should we Hire Flutter Developer to build a fantastic application?

If you’re baffled due to all such questions popping up in your mind, don’t worry, this article has your back! Here we will discuss the best Flutter app development practices to obtain seamless results in 2023. So, let’s get started.

1. Create a Pure Build Function

The construction procedure was devised in such a manner that it must be unadulterated/pure. This is due to a few outside factors, some of which are listed below, which can cause a new widget creation:

  • Pop/push route
  • Recreating its child, the parent widget
  • Typically due to keyboard look or orientation changes, screens are resized
  • An inherited widget depends on a change in class or context.

Simply put, you must bypass this because several widgets might lead to bugs and restrict flutter performance optimization:


Widget build(BuildContext context) {

return FutureBuilder(

future: httpCall(),

builder: (context, snapshot) {

// create some layout here




2. Utilize opacity and clipping mindfully

Both clipping and opacity are deemed overpriced. You have to utilize a transient color to draw texts and structures to work around opacity rather than using any random opacity widget to finish the drawing of texts and shapes.

Likewise, you may hire Flutter developer who uses the Fadelnlmage widget to incorporate fading in different pictures. As far as clipping is concerned, it must be enabled whenever required; otherwise, it should remain disabled. But clipping must be used carefully.

The borderRadius property, for instance, can be used to create a rectangle with curved edges. We can avoid using clipping rectangles in this method.

3. Utilize log instead of print

For hassle-free logging into the console, both debugPrint() and print() methods are used. Android occasionally dismisses some log lines if you use print() and the output is too much simultaneously.

You must use debugPrint to avoid this in the future (). Moreover, it’s advisable to use Dart: Developer Log() if your log data contains more information than you need. You can use this to provide the logging output with a little more detail and information. Simply put, you need to:

  • Utilize the “if” condition rather than a ternary operator.
  • Utilize ternary operator in case of single-line cases.
  • Utilize const widgets.

4. Create frames contributing lower than 16ms

Any application in the profile mode must contribute less than 16ms, which aids you in getting enhanced battery life and fewer thermal issues. There might be no specific transitions in the flutter app.

You may consider building apps with the rising use of 120fps devices with frames contributing less than 8ms. This is how an application owner gets a hassle-free experience on different devices. It’s suggested to hire Flutter developer to obtain maximum feats in the apps.

5. If at all possible, use the const keyword

It is possible to reduce the amount of work garbage collectors must do by giving widgets a const constructor. When the app is large enough, or there is a view that is frequently rebuilt, this performance may first appear insignificant but eventually adds up and matters.

Also, more conducive to hot-reloading are const declarations. In addition, the non-essential const keyword should be disregarded. Consider the following code:

const Container(

width: 100,

child: const Text(‘Print it using flutter’)


As const is already deployed on the parent widget, we don’t really need to utilize it for the Text widget.

6. Add crucial solutions that reduce the size of the application

Flutter app development is considered the most extended procedure involving several components, such as scripts and widgets. It consumes overwhelming memory and time while preserving and processing. The app performance, thus, gets adversely impacted.

Are you wondering what to do in those circumstances?

You could use efficient packaging techniques to group the Android applications or hire the best Flutter developers.

This article focused on the Flutter development best practices that can help all Flutter developers work more efficiently in 2023 and beyond. You may consult with a top Flutter Development Company if you need help creating a Flutter app or if you want to work with specialized Flutter developers on your project.
