TypeError: Cannot read property 'isSupported' of undefined Flutter
try replacing:
<script src="https://www.gstatic.com/firebasejs/8.2.5/fire-messaging.js"></script>
with:
<script src="https://www.gstatic.com/firebasejs/8.4.1/firebase-messaging.js"></script>
I am not sure that fire-messaging.js actually exists
