    <thetext>I think this is worth doing, it&apos;s easy to forget to add animation support, so having fields in CSSProperties.json would help.

Since the most common type of animation are discrete ones, we should support:

```
&quot;animation&quot;: &quot;discrete&quot;,
```

but for more complex wrappers:

```
&quot;animation&quot;: {
  &quot;wrapper&quot;: &quot;LengthPropertyWrapper&quot;,
  &quot;flags&quot;: [&quot;IsLengthPercentage&quot;, &quot;NegativeLengthsAreInvalid&quot;]
}
```

For custom wrappers:
```
&quot;animation&quot;: {
  &quot;wrapper&quot;: &quot;PropertyWrapperFlex&quot;
}
```

etc.

and then &quot;animation&quot;: &quot;not-animatable&quot; if unsupported.

That field would be mandatory to add.</thetext>
