One way to fix this issue would be for us to switch to opening URLs in a Chrome custom tab rather than our own webview screen:
Specifically, I reproduced this issue, and then went and opened the same web page in a Chrome custom tab in a non-Flutter app. There, the same
mailto:link successfully opened a mail client, ready to compose a message to the given recipient.[-][url_launcher_android] doesn't open intent hyperlinks from webview[/-][+][url_launcher_android] doesn't open intent hyperlinks from in-app webview (without Custom Tabs)[/+]stuartmorgan-g commentedon Aug 31, 2023
Anyone affected by this issue can
flutter pub upgradeto pick upurl_launcher_android6.1.0 or later, and in supported configurations in-app mode will use Custom Tabs instead of the previous webview, which won't have this issue.tirth-patel-nc commentedon May 15, 2025
