Description

Hi, so i am trying to build a simple prompt which takes in radiolist_dialog() to create a radio list prompt but it has a default option being checked. For example, take my codes below

from prompt_toolkit.shortcuts import radiolist_dialog

radiolist_dialog(
    title="Title here",
    text="Message here",
    values=[
        (False, 'Yes'), 
        (True, 'No'), # Make this default
    ],
).run()

Once run it will output something like this

But what i want is when run it will give me a prompt with "No" being checked first or by default it's "No". Is it possible ? if yes then i would be appreciated if someone tells me how to do so.

Research direction

Start at the radiolist_dialog entry point and trace how the values argument is converted into the radio list's initial state. Add or clarify support for selecting the requested default option, then add a focused test showing that "No" is selected initially and run the relevant test suite.
