The LiveKit Flutter SDK does support RPC (Remote Procedure Calls). Here are the key features: • Method Registration: You can register and unregister RPC methods using

registerRpcMethod()

and

unregisterRpcMethod()

. For example:`room.registerRpcMethod('echo', (RpcInvocationData data) async { return 'echo: => ${data.callerIdentity} ${data.payload}'; });` • Method Invocation: You can invoke RPC methods on remote participants using

performRpc()

. For example:`var response = await room.localParticipant?.performRpc(PerformRpcParams( destinationIdentity: room.localParticipant!.identity, method: 'echo', payload: 'hello', ));` • Core RPC Types: The SDK includes dedicated types for RPC operations, such as: ◦

PerformRpcParams

for method invocation parameters ◦

RpcInvocationData

for incoming RPC request data ◦

RpcError

for error handling ◦

RpcRequestHandler

typedef for handler functions • Error Handling: The SDK supports error handling with predefined error codes like

unsupportedMethod

,

requestPayloadTooLarge

,

responseTimeout

, and

applicationError

. • Payload Limits: RPC requests and responses have a maximum payload size of 15 KB (15,360 bytes). Additionally, there is a complete Flutter RPC demo application available in the LiveKit examples repository for reference.
