还有一个codelab:

但是一般app会有自己的design system, 所以还是需要自己的theme.
object AppTheme {
val colors: AppColors
@Composable
@ReadOnlyComposable
get() = LocalColors.current
val typography: AppTypography
@Composable
@ReadOnlyComposable
get() = LocalTypography.current
val dimensions: AppDimensions
@Composable
@ReadOnlyComposable
get() = LocalDimensions.current
}
字体也是一样, 最后用了:
internal val LocalTypography = staticCompositionLocalOf { AppTypography() }
