It was once recommended to use componentWillReact()
to trigger layout animations in response to changes in observable values, like so:
componentWillReact() {
LayoutAnimation.configureNext(LayoutAnimation.Presets.spring);
}
However, componentWillReact()
has been removed in mobx-react@6.
What is the recommended replacement? My observable class should know nothing about it's observer, so I'm looking for a similar event-driven solution.
Thanks!
If I got your question correctly, and you have a chance to use functional component, try the
useLayoutEffect
hook instead ofcomponentWillReact
, declare observable value as its deps, and callLayoutAnimation.configureNext
in hook's callback, like this:
