Acr.UserDialogs Prompt

How can I get the text the user entered from a UserDialogs Prompt? I have tried to find examples but can't. I am able to get the dialog to show with the following code:
`var config = new PromptConfig()
{
Title = "Enter the returning job number. If you don't have the job number just tap on Ok."
};

        UserDialogs.Instance.Prompt(config);`

I also need to know if the user tapped on the Cancel button.
