That is a great suggestion but I didn't ask to minify the code, it was done automatically by Flutter web release code.

I will see if this is configurable.

Again, that's not something I did. It's Flutter magic.

Flutter web apps are expected to run on a list of browsers available at https://docs.flutter.dev/platform-integration/web/faq#which-web-browsers-are-supported-by-flutter

Let's see if the fixed href solves your issue too.
