reactjs - Ex-navigation Tab Bar background color change from particular screen -


i change background color of tab bar when changing tabs.

i tried changing state of tab bar when title of tab rendering it's not working because starts rendering infinity times , app crashes:

rendericon = (isselected, title) => {         if (title === 'home') {          } else if (title === 'profile') {             if (isselected) {                 this.setstate({ isdefault: false });                 return (<image                     style={{ width: 29, height: 24, margintop: 8, marginbottom: 1 }}                     source={images.profileselected}                 />);             }              return (<image                 style={{ width: 29, height: 24, margintop: 8, marginbottom: 1 }}                 source={images.profile}             />);         }          render() {            return (             <tabnavigation                 ref='tabber'                 id="main"                 navigatoruid="main"                 initialtab="getticket"                 tabbarstyle={this.state.isdefault ? styles.tabbargreen : styles.tabbarwhite}             >

i tried screen change background color:

this.props.navigation.performaction(({ tabs, stacks }) => {   tabs('main').tabbarstyle = { backgroundcolor: 'green' } });

but doesn't rerender tab bar because there no change in state , nothing happens. how can achieve that?

here example:
