MaterialTheme

Common

Material Theming refers to the customization of your Material Design app to better reflect your product’s brand.

Material components such as [Button] and [Checkbox] use values provided here when retrieving default values.

All values may be set by providing this component with the [colorScheme][ColorScheme], [typography][Typography] and [shapes][Shapes] attributes. Use this to configure the overall theme of elements within this MaterialTheme.

Any values that are not set will inherit the current value from the theme, falling back to the defaults if there is no parent MaterialTheme. This allows using a MaterialTheme at the top of your application, and then separate MaterialTheme(s) for different screens / parts of your UI, overriding only the parts of the theme definition that need to change.
