How to display confirmation message in Tapestry5?

Question

I am developing a website as part of my project last year and I want to display a message confirming that an email has been sent.

I know how to display user error messages in the form, that is, you cannot go further until the following errors are fixed: the username is unknown!

I want to display a message that says: your message has been sent! after sending the email. I was told that I should display this message through a flash.

I am not sure how to do this, any help would be greatly appreciated.

<span t:type="If" t:test="messageSent">Your message was sent.</span>

public boolean isMessageSent() {
    return this.messageSent;
}

@OnEvent(EventConstants.SUCCESS)
void onSendMessage() {
    ...
    this.messageSent = true;
}
