如何在NativeScript中实现网络连接检测？

npm install nativescript-plugin-connectivity

import * as connectivity from "nativescript-plugin-connectivity";

connectivity.startMonitoring(function (newConnectionType: number) {
    switch (newConnectionType) {
        case connectivity.connectionType.none:
            console.log("No network connection");
            break;
        case connectivity.connectionType.wifi:
            console.log("WiFi network connection");
            break;
        case connectivity.connectionType.mobile:
            console.log("Mobile network connection");
            break;
    }
});

connectivity.stopMonitoring();
