Shapes

Class

class Shapes(
    val extraSmall: CornerBasedShape = ShapeDefaults.ExtraSmall,
    val small: CornerBasedShape = ShapeDefaults.Small,
    val medium: CornerBasedShape = ShapeDefaults.Medium,
    val large: CornerBasedShape = ShapeDefaults.Large,
    val extraLarge: CornerBasedShape = ShapeDefaults.ExtraLarge,
)

Material surfaces can be displayed in different shapes. Shapes direct attention, identify components, communicate state, and express brand.

The shape scale defines the style of container corners, offering a range of roundedness from square to fully circular.

There are different sizes of shapes:

  • Extra Small
  • Small
  • Medium
  • Large
  • Extra Large

You can customize the shape system for all components in the MaterialTheme or you can do it on a per component basis.

You can change the shape that a component has by overriding the shape parameter for that component. For example, by default, buttons use the shape style “full.” If your product requires a smaller amount of roundedness, you can override the shape parameter with a different shape value like MaterialTheme.shapes.small.
