KeyEvent on focus JavaFX FXML

I am currently working on an instant messaging program and have created a text for the user to enter a message in the FXML.

How do I add a KeyEvent for when enter is pressed while the text field has focus.

Update - Tried, but doesn't work

<TextArea fx:id="area_chatInput"
       editable="true"
       prefHeight="60"
       prefWidth="300"
       wrapText="true"
       promptText="Enter Message />


@FXML
private void keyListener(KeyEvent event){
    if(event.getCode() == KeyCode.ENTER){
        System.out.println("enter pressed");
        sendMsg();
        event.consume();
    }
}

You can add onKeyPressed event listener to your TextField in the fxml.

...
<TextField fx:id="chatText" layoutX="199.0" layoutY="174.0" onKeyPressed="#keyListener" />
...

In the controller, declare a method keyListener

public void keyListener(KeyEvent event){
    if(event.getCode() == KeyCode.ENTER) {
          // Do stuff
          ((TextField)event.getSource()).clear(); // clear textfield
          System.out.println("Enter Pressed"); // print a message
     }
}

Update - According to comments

To avoid the cursor step to next line, you need to consume the event, before it leaves the method.

...
if (event.getCode() == KeyCode.ENTER) {
     ...
     event.consume(); // Consume Event
}
...
