How to set default props values to custom state less component in React Native -


i have simple component, called divider here source code:

import react "react"; import { stylesheet, view } "react-native";  export default class divider extends react.component {   render() {     return (       <view style = { styles.separator } />     );   } }  const styles = stylesheet.create({   separator: {     height: stylesheet.hairlinewidth,     marginbottom: 8,     backgroundcolor: "#ffffff80",   }, });

what trying achieve values in styles.separator becomes default values of component, since values using in cases, in edge cases need change marginbottom 16 example.

so case want <divider />, <divider marginbottom = 16 />

what have below, doesn't work.

import react "react"; import { stylesheet, view } "react-native";  export default class divider extends react.component {   static defaultpropts = {     margintop: 0,     marginbottom: 8,     backgroundcolor: "#ffffff80",   }    render() {     return (       <view style = {{         height: stylesheet.hairlinewidth,         margintop: {this.props.margintop},         marginbottom: {this.props.marginbottom},         backgroundcolor: {this.props.backgroundcolor},       }} />     );   } }

you can receive custom style props , use them in component style array. when call props style after component's, overwrite equal style property has.

for example, let's have component named 'card', can write component this:

<view style={[style.cardstyle, props.style]}>   {props.children} </view>

and call <card style={{ backgroundcolor: '#ffffff'}} />

so it's getting defined 'cardstyle' it's own component, adding styles received props.

hope helps.

edit:

you can try this

import react "react"; import { stylesheet, view } "react-native";  const divider = (props) => {       <view style = {{         height: stylesheet.hairlinewidth,         margintop: {this.props.margintop},         marginbottom: {this.props.marginbottom},         backgroundcolor: {this.props.backgroundcolor},       }} /> }  divider.defaultprops = {     margintop: 0,     marginbottom: 8,     backgroundcolor: "#ffffff80",   }  export default divider;

let me know if works you.
