BackHandler.removeEventListener Issue

[vinitninjatech]

removeEventListener method is removed so on component unmount it's causing a crash.

componentWillUnmount() { BackHandler.removeEventListener(HARDWARE_BACK_PRESS_EVENT, this.onHardwareBackPress); }

Please check Dialog.js

Fixes :

Add In Constructor
this.backHandler = null;

Update DidMount

componentDidMount() { if (this.props.visible) { this.show(); } // BackHandler.addEventListener(HARDWARE_BACK_PRESS_EVENT, this.onHardwareBackPress); this.backHandler = BackHandler.addEventListener( HARDWARE_BACK_PRESS_EVENT, this.onHardwareBackPress ); }

Update UnMount
componentWillUnmount() { // BackHandler.removeEventListener(HARDWARE_BACK_PRESS_EVENT, this.onHardwareBackPress); if (this.backHandler && typeof this.backHandler.remove === 'function') { this.backHandler.remove(); } }
