A motion scheme provides all the `FiniteAnimationSpec`s for a `MaterialTheme`.

Motion schemes are designed to create a harmonious motion for components in the app.

There are two built-in schemes, a `standard` and an `expressive`, that can be used as-is or
customized.

You can customize the motion scheme for all components in the `MaterialTheme`.


## Functions

```kotlin
fun <T> defaultSpatialSpec(): FiniteAnimationSpec<T>
```


A default spatial motion `FiniteAnimationSpec`.

This motion spec is designed to be applied to animations that may change the shape or bounds
of the component. For color or alpha animations use the `effects` equivalent which ensures a
"non-spatial" motion.

`T` is the generic data type that will be animated by the system, as long as the appropriate
`TwoWayConverter` for converting the data to and from an `AnimationVector` is supplied.


```kotlin
fun <T> fastSpatialSpec(): FiniteAnimationSpec<T>
```


A fast spatial motion `FiniteAnimationSpec`.

This motion spec is designed to be applied to animations that may change the shape or bounds
of the component. For color or alpha animations use the `effects` equivalent which ensures a
"non-spatial" motion.

`T` is the generic data type that will be animated by the system, as long as the appropriate
`TwoWayConverter` for converting the data to and from an `AnimationVector` is supplied.


```kotlin
fun <T> slowSpatialSpec(): FiniteAnimationSpec<T>
```


A slow spatial motion `FiniteAnimationSpec`.

This motion spec is designed to be applied to animations that may change the shape or bounds
of the component. For color or alpha animations use the `effects` equivalent which ensures a
"non-spatial" motion.

`T` is the generic data type that will be animated by the system, as long as the appropriate
`TwoWayConverter` for converting the data to and from an `AnimationVector` is supplied.


```kotlin
fun <T> defaultEffectsSpec(): FiniteAnimationSpec<T>
```


A default effects motion `FiniteAnimationSpec`.

This motion spec is designed to be applied to animations that do not change the shape or
bounds of the component. For example, color animation.

`T` is the generic data type that will be animated by the system, as long as the appropriate
`TwoWayConverter` for converting the data to and from an `AnimationVector` is supplied.


```kotlin
fun <T> fastEffectsSpec(): FiniteAnimationSpec<T>
```


A fast effects motion `FiniteAnimationSpec`.

This motion spec is designed to be applied to animations that do not change the shape or
bounds of the component. For example, color animation.

`T` is the generic data type that will be animated by the system, as long as the appropriate

bounds of the component. For example, color animation.

`T` is the generic data type that will be animated by the system, as long as the appropriate
