Experiment to allow animating fillOpacity of Rect using native driver.
import React, { Component } from 'react';
import { StyleSheet, View, Dimensions, Animated } from 'react-native';
import { Svg, Rect } from 'react-native-svg';
const { width, height } = Dimensions.get('window');
const AnimatedRect = Animated.createAnimatedComponent(Rect);
export default class App extends Component {
state = {
anim: new Animated.Value(0),
};
componentDidMount() {
Animated.timing(this.state.anim, {
toValue: 1,
duration: 3000,
useNativeDriver: true,
}).start();
}
render() {
const { anim } = this.state;
return (
<View style={styles.container}>
<Svg width={width} height={height} viewBox="0 0 100 100">
<AnimatedRect
x="5"
y="5"
width="90"
height="90"
fill="green"
fillOpacity={anim}
/>
</Svg>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
backgroundColor: '#ecf0f1',
},
});
