Top Flutter WebSocket and RPC packages
Last updated: January 26, 2025
WebSocket enables real-time and two-way communication between a client and a server, and is popularly used by applications handling real-time data such as chat applications, online gaming and live data streaming.
Whereas, Remote Procedure Call or RPC is a protocol that allows a program to execute code on another address space, typically on a remote server, as if it were a local function call. It abstracts the complexities of remote communication by enabling developers to invoke functions on a different system without dealing with low-level networking details. RPC is used to build distributed systems, where different components or services communicate seamlessly. There are various implementations of RPC, such as gRPC, which use protocols like HTTP/2 for communication. RPC is widely utilized in micro-services architectures and client-server applications, enhancing modularity and scalability.
WebSocket and RPC can be used for building efficient and interactive applications across different domains. Below you will find the top packages that can help you add WebSocket and RPC support in your Flutter apps easily.
