Making phone call from a flutter app : <p>I try to make a phone call from my Flutter app. With the following code:</p>

<pre><code>UrlLauncher.launch('tel: xxxxxxxx');
</code></pre>

<p>I found this Function on the github flutter repo: <a href="https://github.com/flutter/flutter/issues/4856" rel="noreferrer">https://github.com/flutter/flutter/issues/4856</a></p>

<p>But this don't work for me. Is this Function still in Flutter and in which package? Or is there an better option to do an phone call from my app? </p>
