How to open Viber app in Flutter web app?

Question

I want to open Viber app (Android / Windows) from flutter web application. I tried using url_launcher but it does not work.

The URL to open Viber chat is viber://chat?number=xxx. How can I call this from flutter web app?

Answer 1

Searching for the same solution but only for a mobile app, Google gives me only this question. So, I decided to write the research results here. Maybe it will come in handy.

For a mobile app, you can use url_launcher

launch('viber://chat?number=$phoneNumber');

If you want to open the conversation with a predefined text, you can write like this:

launch('viber://chat/?number=$phoneNumber&draft=$yourMessage');

Please note, if Viber is not installed on your device, the launch method throws an error.

After that

html.window.open('viber://chat?number=xxx', '');
