Real-time communications (RTC) are the near simultaneous exchange of information over any type of telecommunications service from the sender to the receiver in a connection with negligible latency, according to Search Unified Communications. Examples of real-time communications include:

  • Voice over landlines and mobile phones
  • VoIP
  • Instant messaging (e.g., WhatsApp, WeChat, Facebook Messenger)
  • Video and teleconferencing
  • Robotic telepresence

Real-time communications can take place in half-duplex or full-duplex modes:

  • Half-duplex RTC. Data transmission can happen in both directions on a single carrier or circuit but not at the same time.
  • Full-duplex RTC. Data transmission can occur in both directions simultaneously on a single carrier or circuit.

Knowing these basic details, let’s list the 10 most popular Flutter libraries about RTC:

1. socket_io_client

Port of awesome JavaScript Node.js library v2.0.1~v3.0.3 in Dart

9. socket_io

Port of JS/Node library It enables real-time, bidirectional and event-based communication cross-platform. Same as Socket.IO, this project allows you to create several Namespaces, which will act as separate communication channels but will share the same underlying connection.

10. callkeep

iOS CallKit framework and Android ConnectionService for Flutter. Support FCM and PushKit.

Callkeep acts as an intermediate between your call system (RTC, VOIP…) and the user, offering a native calling interface for handling your app calls. This allows you (for example) to answer calls when your device is locked even if your app is terminated.

I have worked with Agora, Jitsi, WebRTC and CallKeep in my projects, which together with FCM, you can create professional communication tools.
