如何使用 android_intent 包启动另一个应用程序？

将以下内容添加到 pubspec.yaml 下的 dependencies：

 device_apps:
 android_intent:
 url_launcher:

添加以下代码：

 _openSecondApp(data) async {
     String dt = data['SecondApp'] as String;
     bool isInstalled = await DeviceApps.isAppInstalled('com.example.secondapp');

     if (isInstalled != falsE) {
         AndroidIntent intent = AndroidIntent(action: 'action_view',data: dt);
         await intent.launch();
     } else {
         String url = dt;

         if (await canLaunch(url))
             await launch(url);
         else
             throw 'Could not launch $url';
     }
 }
