如何从 Flutter 应用程序打开另一个应用程序（我自己的应用程序）？

Question

I have two applications. customer app and vendor app. How to open vendor app from customer app when click button ?

Is it possible to open another application from the Flutter app?

com.demo.customer and com.demo.vendor

I tried url_launcher . but It cannot give package name and open another application.

And also I tried this package, device_apps but not working for ios.

Should be work on Android and ios.

Answer 1

You need to register a custom url scheme for the app you want to open.

You can read more here:

For iOS: iOS Documentation

For Android: Android Documentation

There's also a nice plugin that can handle deeplink actions for Flutter.

Flutter Uni Links

When you have registered a custom url scheme (for example: demo://vendor) you can just call that url with url_launcher plugin:

launchUrl('demo://vendor')
