Xterm.js: Unable to detect `ENTER` key event with => xterm[4.2.0] onKey() method

[goxr3plus]

Using the latest version of xterm.js 4.2.0 i want to be able to detect key events and pass them on the terminal , i am not able to detect when ENTER or ALT or SHIFT is pressed like i used to with older version 3.x.x

Why Enter is returning "" ?

What i have done:

    term.onKey(key => {
      const char = key;
      console.log(key);
      console.log(char.key === "");
      if (char === "") {
        console.log("Enter pressed");
        prompt();
      } else {
        term.write(char);
      }
    });

  prompt = () => {
    var shellprompt = "$ ";
    term.write("\r\n" + shellprompt);
  };

I am a new user of the library :)

It's there you'll find it's actually \r:

That is what a terminal emulator would normally send to a shell. If key doesn't have what you're after we also expose the KeyboardEvent directly:

@Tyriar You are amazing you know that :) ?

I ended up using KeyboardEvent => keyboardEvent.domEvent.key
