airplane mode always returns false inside render method react native android

[hanaechahid]

Hello, I'm using this module to detect if airplane mode is enabled or not inside my react native application. when I call the state inside component did mount it returns true if airplane is enabled and false if is disabled, but when I call it on render method it always return false.
this how my code looks:
componentDidMount() { SystemSetting.isAirplaneEnabled() .then((enable) => { this.setState({ airplanemode: enable }) alert(this.state.airplanemode); //here works fine }) // here didn't work fine alert(this.state.airplanemode); }
render method:
render() { alert(this.state.airplanemode) // here always return false return () }
