Top 10 Flutter Packages for Real-Time Communication

Vigneshwar Published On March 20th, 2024 Tech Talks

Explore our hand-picked flutter packages for enabling real-time communication in your apps.

Real-time communication (RTC) is a key component in mobile app development since it lets you add communication features easily and quickly. From days of long-distance phone calls via landlines to the present era of video conferencing and instant messaging, RTC has played an important role in the evolution of online communication. 

When it comes to RTC, It can happen in 2 modes:

1. Half-duplex 
2. Full-duplex 

While full-duplex RTC allows for simultaneous data transfer in both ways, half-duplex RTC allows for data transmission in both directions but not simultaneously.

Now, you may ask which question is best for building RTC for your business. 

Evidently, the market for effective real-time communication packages has expanded as Flutter’s popularity as a cross-platform framework continues to grow. Yes, developers around the world consider Flutter as a reliable technology to improve their apps with highly interactive communication features.

In this article, we will look at the top 10 Flutter libraries that are used for real-time communication. With the wide range of features these libraries provide, Flutter developers can design dynamic and captivating apps easily.

Let’s take a look at the Flutter package list.
