closeAfterTransitionbooleanfalse

When set to true the Modal waits until a nested Transition is completed before closing.

containerPortalProps['container']-

An HTML element or function that returns one. The container will have the portal children appended to it.
You can also provide a callback, which is called in a React layout effect. This lets you set the container from a ref, and also makes server-side rendering possible.
By default, it uses the body of the top-level document object, so it's simply document.body most of the time.

If true, hitting escape will not fire the onClose callback.

disableScrollLockbooleanfalse

Disable the scroll lock behavior.

onClose{ bivarianceHack(event: {}, reason: 'backdropClick' | 'escapeKeyDown'): void }['bivarianceHack']-

Callback fired when the component requests to be closed. The reason parameter can optionally be used to control the response to onClose.

onTransitionExited() => void-

A function called when a transition has exited.
