How to get cursor position from q-editor?

[QuasarDeveloper]

I am able to get the cursor position with this, but it only detects the first line. It bugs out when a user goes to a new line. This is my current code:

    setCursorPosition() {
      const range = window.getSelection();
      if (range !== null || range !== undefined) { 
        this.editorCursorPosition = range.focusOffset;
      } else {
        this.editorCursorPosition = 0
      }
    },
