CardModifier class

A Material Design card: a panel with slightly rounded corners and an elevation shadow.

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.

{@tool dartpad} 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.

{@tool dartpad} 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.

Material Design 3 introduced new types of cards. These can be produced by configuring the Card widget's properties. Card widget. {@tool dartpad} This sample shows creation of Card widgets for elevated, filled and outlined types, as described in: https://m3.material.io/components/cards/overview
