I created a new react-native project today (April 3rd, 2020) and added a native-base. Then I tried to add input with the floating label. It gives a warning message: Animated: useNativeDriver
was not specified. This is a required option and must be explicitly set to true
or false
. If I removed the floating label attribute or changed it to stackedLabel the warning disappeared. While this warning is appearing, onChangeText
is not being called.

const App = () => {
return (

Just add useNativeDriver: true
to the animation config.
const [animatePress, setAnimatePress] = useState(new Animated.Value(1))
const animateIn = () => {
Animated.timing(animatePress, {
toValue: 0.5,
duration: 500,
useNativeDriver: true // Add This line
}).start();
}
Solution:
As the warning says, we need to specify the useNativeDriver
option explicitly and set it to true
or false
.
1- Animation methods
Refer to Animated doc , with animation types or composition functions, for example, Animated.decay()
, Animated.timing()
,
Animated.spring()
, Animated.parallel()
, Animated.sequence()
, specify useNativeDriver
.
Animated.timing(this.state.animatedValue, {
toValue: 1,
duration: 500,
useNativeDriver: true, // Add this line
}).start();
2- Animatable components
Animated
exports the following animatable components using the above wrapper:
Animated.Image
Animated.ScrollView
Animated.Text
Animated.View
Animated.FlatList
Animated.SectionList
When working with Animated.event()
, add useNativeDriver: false/true
to the animation config.
<Animated.ScrollView
scrollEventThrottle={1}
onScroll={Animated.event(
[{ nativeEvent: { contentOffset: { y: this.state.animatedValue } } }],
{ useNativeDriver: true } // Add this line
)}
>
{content}
</Animated.ScrollView>
Facing the same issue for a long time and still no update from native-base developers yet in 2021.
Meanwhile use a workaround to avoid irritating yellow warnings of useNativeDriver
.
YellowBox
is now changed and replace with LogBox
FUNCTIONAL
import React, { useEffect } from 'react';
import { LogBox } from 'react-native';
useEffect(() => {
LogBox.ignoreLogs(['Animated: `useNativeDriver`']);
}, [])
CLASS BASED
import React from 'react';
import { LogBox } from 'react-native';
componentDidMount() {
LogBox.ignoreLogs(['Animated: `useNativeDriver`']);
}
FUNCTIONAL
import React, { useEffect } from 'react';
import { YellowBox } from 'react-native';
useEffect(() => {
YellowBox.ignoreWarnings(['Animated: `useNativeDriver`']);
}, [])
CLASS BASED
import React from 'react';
import { YellowBox } from 'react-native';
componentDidMount() {
YellowBox.ignoreWarnings(['Animated: `useNativeDriver`']);
}
Seem to be a known bug of current nativebase.io Release: https://github.com/GeekyAnts/NativeBase/issues/3109
Additional Info, what exactly the issue is about: https://reactnative.dev/blog/2017/02/14/using-native-driver-for-animated#how-do-i-use-this-in-my-app
use the following code to avoid the warning message of usenativedriver
Animated.timing(new Animated.Value(0),
{
toValue: 1,
duration: 500,
easing: Easing.linear,
useNativeDriver: false //make it as false
}).start();
When using Animated.spring
or any other Animation specify useNativeDriver: true
of useNativeDriver: false
.
Example:
Animated.spring(this.position, {
toValue: { x: 0, y: 0 },
useNativeDriver: true,
}).start();
The Animated.spring
is being called in onPanResponderRelease
function.
In react native SDK 39 you have to write following code:
LogBox.ignoreLogs(['Animated: `useNativeDriver` was not specified.']);
native-base fixed this as of January. Get at least v2.15.2
yarn add native-base@^2.15.2
