Please describe the feature you would like to request.

We need to add custom validators which useful for form validation. If Angular Material will provide inbuilt validator then people save their time

What is the use-case or motivation for this proposal?

We need to create common validators such as #

• rangeLength
• min
• gt
• gte
• max
• lt
• lte
• range
• digits
• number
• url
• email
• date
• minDate
• maxDate
• dateISO
• creditCard

Is there anything else we should know?

This is not Material specific. I think it would be more appropriate as part of @angular/forms instead. In fact, some of those are already provided in Angular's validators.

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.
