I'm trying to make a wrapper component in react-native that I can pass down all its props to the children it wraps around. What I really want is to pass down all function props down to all its children. It looks something like this below. I want the onPress in Wrapper to be called when the TouchableOpacity is pressed.
I tried this below but it doesn't work
const Wrapper = ({children,...props})=>{
return <View {...props}>{children}</View>
}
const App = ()=>{
return (
<View style={{flex:1}}>
<Wrapper onPress={()=>{console.log(2)}}>
<TouchableOpacity/>
</Wrapper>
</View>
)
}
const App = () => {
return (
<View style={{ flex: 1 }}>
<TouchableOpacity onPress={() => {
// do the action need here here
}}>
<Wrapper >
</Wrapper>
</TouchableOpacity>
</View>
)
}
I would advise you to use hooks function instead
If you try to reuse functions that are related ** useAdd.js **
export default () => {
const addFuction(a, b) => {
// do preprocessing here
return a + b
}
return [addFuction]
}
main componet
import useAdd from "/useAdd";
const App = () => {
const [addFuction] = useAdd()
return (
<View style={{ flex: 1 }}>
<TouchableOpacity onPress={() => {
addFuction(4,5)
}}>
...action component...
</TouchableOpacity>
</View>
)
}
console in useAdd hook.... to see visual changes use the react useState
It looks like you're looking to map the children and apply the props to each one. That might look like this:
const Wrapper = ({children,...props})=>{
return (<>
{React.Children.map(children, child => (
React.cloneElement(child, {...props})
))}
</>);
}
(method of mapping the children borrowed from this answer)
