"No overload" on socket.send(string, number, string, function)

Description

socket.send() seems to be incorrectly overloaded when used in a React Native Typescript app. See below for details.

Steps to reproduce

My code:

import dgram from "react-native-udp";
...
sendMessage() {
  let socket = dgram.createSocket('udp4');
  socket.send("abcd", 64456, "127.0.0.1", (err: Error) => {
    if (err) throw err;
    console.log('message sent');
  });
}

Current behavior

My IDE (VSCode) shows an error on the code above, complaining about an overload error on the 3rd parameter:

No overload matches this call.
  The last overload gave the following error.
    Argument of type '"127.0.0.1"' is not assignable to parameter of type 'number'. ts(2769)

index.d.ts(58, 7): The last overload is declared here.

When I try to run the code on an Android emulator, I get the error Error: invalid port. Probably because my address (string) is trying to be interpreted as the port (number).

Expected behavior

The arguments string, number, string, function(Error) => void should use the msg, port, addr, callback overload, but it seems to be trying to use a different overload. Perhaps it is defaulting to the msg, offset, length, callback overload?

Unfortunately I’m quite new to React Native and Typescript so I can’t offer any fixes, but I’m happy to try out possible solutions if need be.

Gotcha, thanks for the quick response. The code you suggested failed with a similar error, but adding the size parameter works for me 😃.

It seems that index.d.ts includes a function declaration where the parameters are option. Would that be removed in a “complete refresh of the declaration files”?
