Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

18.0.7

Description

Since switch to @inquirer/prompts library, x-prompt no longer supports providing default options for properties with type list that support multiselect. It's related to changes in the API comparing to previous inquirer package. Now, the default value can be set by checked flag which is part of each object in choices array: https://github.com/SBoudrias/Inquirer.js/tree/main/packages/checkbox#choice-object

PR: #28842
I'm happy to contribute and I'd appreciate a guidance to not miss any place that could be affected and should be adjusted.

Minimal Reproduction

To reproduce the issue, clone the following repository and go to its location:

git clone https://github.com/pawelfras/x-prompt-list-issue.git

Run npm install to install dependencies and build the project by running ng build.

To test with latest version of @angular/cli, run:

npx @angular-devkit/schematics-cli@latest .:x-prompt-list-issue

Hit enter without any custom selection and see the expected output:

? Choose numbers (1 and 3 should be selected by default) 
Selected numbers: []
Nothing to be done.

npx @angular-devkit/schematics-cli@18.0.7 .:x-prompt-list-issue
