A card is a sheet of Material used to represent some related information, for example an album, a geographical location, a meal, contact details, etc.

This is what it looks like when run:

A card with a slight shadow, consisting of two rows, one with an icon and
some text describing a musical, and the other with buttons for buying
tickets or listening to the show.

This sample shows creation of a Card widget that shows album information and two actions.

Sometimes the primary action area of a card is the card itself. Cards can be one large touch target that shows a detail screen when tapped.

This sample shows creation of a Card widget that can be tapped. When tapped this Card's InkWell displays an "ink splash" that fills the entire card.
To create a local project with this code sample, run:
flutter create --sample=material.Card.2 mysample

Material Design 3 introduced new types of cards. These can be produced by configuring the Card widget's properties. Card widget.

This sample shows creation of Card widgets for elevated, filled and outlined types, as described in: https://m3.material.io/components/cards/overview
