How to use LayoutAnimation on Android using react native - react-native

Question

LayoutAnimation not working on android
I didn't find any issues like this, and these errors are not found in google)
"react-native": "0.67.4"
I try to use LayoutAnimation, my code looks like this:
constructor(props) {
super(props)
this.state = {
height: Dimensions.get('window').height,
sliderTopPosition: Dimensions.get('window').height/2-50
}
if (Platform.OS === 'android') {
UIManager.setLayoutAnimationEnabledExperimental &&
UIManager.setLayoutAnimationEnabledExperimental(true);
}
}
kbShow = (event) => {
LayoutAnimation.configureNext(LayoutAnimation.create(
event.duration,
LayoutAnimation.Types[event.easing] //'keyboard'
// LayoutAnimation.Types.easeInEaseOut
), () => {
// console.log(finish, 'finish')
}, () => {
console.log('KEYBOARD SHOW ANIMATION DID FAIL')
})
this.setState({
height: event.endCoordinates.screenY,
sliderTopPosition: this.state.sliderTopPosition-event.endCoordinates.height+150,
})
}
And it works fine on iOS, but if I try to run this code on android I get an error:
Unsupported interpolation type : keyboard
Ok, I replace this strings like this just for test:
//LayoutAnimation.Types[event.easing] //'keyboard'
LayoutAnimation.Types.easeInEaseOut
It still works on ios but not on android
And now error is like this:
Invalid layout animation : {NativeMap: {"type": easeInEaseOut}}
And no matter what type of easing I use it always throw this error

To make it work on Android, you need to supply a property:
LayoutAnimation.configureNext(LayoutAnimation.create(
event.duration,
LayoutAnimation.Types[event.easing],
'opacity'
)
The property can be either 'opacity', 'scaleX', 'scaleY' or 'scaleXY'.
It's a very misleading error message and the type checking should show that the property is required...
