react-native-animateable-text
A fork of React Native's <Text/>
component that supports Reanimated Shared Values as text!
Compatibility
(🚨 Make sure you use the correct version for your RN project)
Installation
First make sure you have reanimated already installed and linked from here then run
yarn add react-native-animateable-text
then for Expo managed projects you need to prebuild your project, and for ReactNative bare projects you should run
npx pod-install
Usage (Reanimated 2/3)
Note about Reanimated 2: The library does not work with Alpha 9 until RC1. Make sure to update to RC2 or later!
Use it the same as a <Text/>
component, except instead of passing the text as a child node, pass it using the text
props.
import AnimateableText from 'react-native-animateable-text';
const Example: React.FC = () => {
const reanimatedText = useSharedValue('World');
const animatedProps = useAnimatedProps(() => {
return {
text: reanimatedText.value,
};
});
return (
<AnimateableText
animatedProps={animatedProps}
// all other <Text /> props are also available
/>;
};
OMG, why would you build this?
We want to animate numbers based on gestures as fast as possible, for example for charts displaying financial data. Updating native state is too slow and not feasible for a smooth experience. Using createAnimatedComponent
doesn't allow you to animate the text since the children of Text are separate nodes rather than just props.
The best way so far has been to use the <ReText>
component from react-native-redash, which allows you to render a string from a Reanimated Text node. However, under the hood, it uses a <TextInput/>
and animates it's value
prop.
This naturally comes with a few edge cases, for example:
