Here's a weekly mini calendar, that turns into a monthly mini calendar component.
When it turns from weekly to monthly we have some entering/exiting animations So far so good.
Problem:
The problem is, that those animations (being entering/exiting animations) also take place while the user is scrolling.
As you can see in the gif, animations play when I scroll horizontally, which isn't what I want, I only want animations when the component changes from weekly to monthly (expands/collapses)
Code:
import Animated, {
FadeInDown,
FadeInUp,
SlideOutUp,
SlideOutDown,
} from 'react-native-reanimated';
const MiniCalendarItem = () => {
let animationEnter;
let animationExit;
if (this.props.itemRepresents === ITEM_REPRESENTS.MONTH) {
if (this.dayIsPartOfCurrentWeek(day)) {
animationEnter = FadeInUp;
} else {
animationEnter = FadeInUp.delay((weekIndex * 150)).duration(350)
}
animationExit = SlideOutDown.duration(400);
} else {
animationEnter = FadeInDown.duration(500);
animationExit = SlideOutUp.duration(400);
}
return (
<Animated.View
entering={animationEnter}
exiting={animationExit}
key={`dayData_${dayProps.id}`}
>
{...}
</Animated.View>
);
};
and here's the parent:
renderItem = () => {
return (
<MiniCalendarItem
animationsEnabled
key={itemKey}
mode={mode}
itemRepresents={visible ? ITEM_REPRESENTS.MONTH : ITEM_REPRESENTS.WEEK}
/>
)
}
}
Essentially the parent is a ScrollView
(not a FlatList
)
Question: How can I stop react-native-reanimated@2 from playing any animations and when is it a good time to do that.
I added a animationsEnabled
prop, but ideally I'd love to feed it with an Animated.Value(true)
object. I'm just not sure how to conditionally disable animations based on that prop, from within the MiniCalendarItem
.
