I am using this method for launching tabs..

static void launchURL(BuildContext context, String url) async {
try {
await launch(
url,
option: CustomTabsOption(
toolbarColor: Theme.of(context).primaryColor,
enableDefaultShare: true,
enableUrlBarHiding: true,
showPageTitle: true,
animation: CustomTabsAnimation.slideIn(),
extraCustomTabs: [
// ref. https://play.google.com/store/apps/details?id=org.mozilla.firefox
'org.mozilla.firefox',
// ref. https://play.google.com/store/apps/details?id=com.microsoft.emmx
'com.microsoft.emmx',
],
),
);
} catch (e) {
debugPrint(e.toString());
}
}

I think this is related to #21
Did you try removing the animation parameter in the CustomTabsOption constructor?
