Flutter For Chat Apps: Is it a Good Choice? 

In simple words, yes. Flutter is simply a great choice to build your messaging app. 

Let me give you the 3 best reasons why:

  1. Single Codebase: You can build your chat app for both Android & iOS with the same set of codes. 
  2. Faster Development: Flutter supports Hot Reload, which means – when you make changes to your code, you can see them in real-time without reloading the entire app. Saves you a lot of time, right? 
  3. Customize, Get Creative: Flutter has a rich set of widget and UI elements. This gives you all the power to add visually appealing and engaging chat app elements like chat bubbles, icons and themes.

How Compatible Is Flutter For Your Chat App? 

Before we get into the compatibility check, let’s check out the list of popular instant messaging apps that are built on Flutter and run on different platforms.

  1. iOS: You can design chat apps with Flutter that function smoothly on iPhones and iPads because it is compatible with iOS. Flutter has been effectively used by well-known messaging apps like Signal and Google Meet for iOS.
  1. Android: Flutter works with Android as well, giving you access to a large user base across a range of Android devices. The Google Messages app and the MeeTime app on Huawei devices are two instances of Android chat apps developed with Flutter.

Fuchsia OS + Flutter

Google’s open-source operating system runs its First-gen Nest Hub devices on Flutter, post its smooth experiences with the technology on Android & iOS. 
  1. Web: Flutter’s web compatibility has advanced significantly. With Flutter, you can build chat applications that function flawlessly in web browsers. While not every chat app has a web version specifically for it, Flutter offers the possibility of having a single codebase for multiple platforms.
  1. Desktop: Flutter is now compatible with desktop operating systems like Linux, macOS, and Windows. A smaller number of chat apps are experimenting with Flutter desktop compatibility. 

So, It is now clear that Flutter can be used on any operating system you choose to create your chat app with. 

But there is a hesitation among developers to use Flutter. It is very important to check the flipside of the technology before you get into your project. Let me jot them down for you. 

What Are The Challenges Of Using Flutter?

Flutter has a lot of benefits, but it’s important to take the drawbacks into account as well. Using Flutter for chat apps could cause the following challenges:

Flutter is a new technology: Flutter is still in its early stages, and some developers are afraid of using it because it looks more suitable for simpler apps or prototypes because the libraries are constantly expanding. Developers frequently worry about devoting effort to something that could change quickly.

Learning a New Language: Developers who work with Flutter are less familiar with Dart when compared to other conventional languages. It takes time to learn a new language, so developers might feel better comfortable sticking with the language they already know.

Cross-Platform Performance Concerns: Although Flutter’s ability to run on multiple platforms is a plus, some worry that it might not work as effectively as a native app. While there is always room for improvement, Flutter is moving in the right direction to match native development’s performance.

Although there are a few downsides, Flutter’s benefits, such as faster development and a single codebase, make it difficult to ignore these concerns. As it gets better, a lot of developers are finding that it’s a good investment for creating apps quickly and stress-free. Considering the advantages Flutter can have for your development process, it might be worthwhile to take the risk.
