DsSurface class

A container that adopts a ColorScheme surface level as its background.

This is the foundational surface primitive of the design system. All layouts and card-like components should be built on top of DsSurface rather than hardcoding colors.

The color is sourced exclusively from Theme.of(context).colorScheme — no color is ever hardcoded.

  level: SurfaceLevel.low,
  borderRadius: AppRadius.card,
  padding: AppSpacing.cardPadding,
  child: Text('Hello'),

Properties

border → BoxBorder?
Optional border drawn on top of the surface.
final
borderRadius → BorderRadius?
Override the default border radius. Defaults to AppRadius.card.
final
child → Widget
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
level → SurfaceLevel
Which M3 surface container tier to use as the background color.
final
padding → EdgeInsetsGeometry?
Inner padding. When null, no padding is applied.
final
runtimeType → Type
A representation of the runtime type of the object.
