[solved ] I cannot find the github link for ionic 4 components demo source examples

I’m looking for the source code of https://ionicframework.com/docs/api/modal,

or in general the all GitHub project with these examples

Where can I find it?

I only can found the [ionic v3 version] https://github.com/ionic-team/ionic-preview-app/blob/master/src/pages/modals/basic/pages.ts


Github is reporting a 404 for the ionic-docs demos e.g. this page . Google doesn’t have a cached version either.
