@td-design/rn-hooks/lib/module/useBackHandler/index.js

从ahooks里面抽取的一些在rn项目里可以使用的hooks。提高开发效率

import { useEffect } from 'react';
import { BackHandler } from 'react-native';

function useBackHandler(handler) {
    useEffect(function () {
        var subscription = BackHandler.addEventListener('hardwareBackPress', handler);
        return function () {
            if (typeof (subscription === null || subscription === void 0 ? void 0 : subscription.remove) === 'function') {
                subscription.remove();
            }
            else {
                // React Native < 0.65
                BackHandler.removeEventListener('hardwareBackPress', handler);
            }
        };
    }, [handler]);
}

export { useBackHandler as default };
