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

Found a solution. I used html package

import 'dart:html' as html;

After that

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