deprecatedConnectToAgentService<T> function

*[<Null safety>](*

void deprecatedConnectToAgentService <T>(String? agentUrl, AsyncProxy<T>? serviceProxy, {dynamic componentContextProxy})

Connect to the service specified by serviceProxy and implemented by the agent with agentUrl. Optionally, provide a componentContextProxy which will be used to connect to the agent. If agentUrl is null then the framework will attempt to automatically resolve an appropriate agent for the service.

The agent will be launched if it's not already running.
