Card class - material library

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.

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.

For Material Design 2 (when ThemeData.useMaterial3 is false), there is a single card type: the elevated card. In that mode the named constructors (Card.filled, Card.outlined) behave the same as the default Card.

For Material Design 3 (when ThemeData.useMaterial3 is true), three visual variants are available: the default Card (elevated), Card.filled, and Card.outlined. All variants share the same theme class, CardThemeData, so theme properties (for example CardThemeData.shape) apply to every card variant within the theme's scope.

Constructors

Card({Key? key, Color? color, Color? shadowColor, Color? surfaceTintColor, double? elevation, ShapeBorder? shape, bool borderOnForeground = true, EdgeInsetsGeometry? margin, Clip? clipBehavior, Widget? child, bool semanticContainer = true}): Creates an elevated variant of Card.
const
Card.filled({Key? key, Color? color, Color? shadowColor, Color? surfaceTintColor, double? elevation, ShapeBorder? shape, bool borderOnForeground = true, EdgeInsetsGeometry? margin, Clip? clipBehavior, Widget? child, bool semanticContainer = true}): Create a filled variant of Card.
const
Card.outlined({Key? key, Color? color, Color? shadowColor, Color? surfaceTintColor, double? elevation, ShapeBorder? shape, bool borderOnForeground = true, EdgeInsetsGeometry? margin, Clip? clipBehavior, Widget? child, bool semanticContainer = true}): Create an outlined variant of Card.

Properties

borderOnForeground → bool: Whether to paint the shape border in front of the child.
final
child → Widget?: The widget below this widget in the tree.
final
clipBehavior → Clip?: The content will be clipped (or not) according to this option.
final
color → Color?: The card's background color.
final
elevation → double?: The z-coordinate at which to place this card. This controls the size of the shadow below the card.
final
hashCode → int: The hash code for this object.
no setterinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
margin → EdgeInsetsGeometry?: The empty space that surrounds the card.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
semanticContainer → bool: Whether this widget represents a single semantic container, or if false a collection of individual semantic nodes.
final
shadowColor → Color?: The color to paint the shadow below the card.
final
shape → ShapeBorder?: The shape of the card's Material.
final
surfaceTintColor → Color?: The color used as an overlay on color to indicate elevation.
