### TextPlaceholder
```kotlin
/**
 * This sample applies a placeholder and placeholderShimmer directly over a single composable.
 *
 * Note that the modifier ordering is important, the placeholderShimmer must be before the
 * placeholder in the modifier chain - otherwise the shimmer will be drawn underneath the
 * placeholder and will not be visible.
