通过Flutter应用拨打电话

我尝试在Android / iOS上运行launch(“tel://214324234”)，效果很好。您需要安装软件包url_launcher并将其导入 import it

import 'package:flutter/material.dart';import 'package:url_launcher/url_launcher.dart';class MyApp extends StatelessWidget {  @override  Widget build(BuildContext context) {    return new MaterialApp(      title: 'Flutter Demo',      home: new Home(),    );  }}class Home extends StatelessWidget {  Home({Key key}) : super(key: key);  @override  Widget build(BuildContext context) => new Scaffold(        appBar: new AppBar(          title: new Text("View"),        ),        body: new Center(          child: new FlatButton(   onPressed: () => launch("tel://21213123123"),   child: new Text("Call me")),        ),      );}void main() {  runApp(    new MyApp(),  );}

您也可以导入它import ‘package:url_launcher/url_launcher.dart’ as UrlLauncher;，然后使用UrlLauncher.launch(“tel://21213123123”)

确保在pubspec.yaml文件的依赖项部分中包含一个条目：url_launcher：^ 1.0.21.0.2
