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

flutter create --sample=material.Card.1 mysample
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.

Material Design 3 introduced new types of cards. The default Card is the elevated card. To create a filled card, use Card.filled; to create a outlined card, use Card.outlined.
This sample shows creation of Card widgets for elevated, filled and
outlined types, as described in: https://m3.material.io/components/cards/overview
