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

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. _______________________________________________ > Therion mailing list > [email protected] > https://mailman.speleo.sk/listinfo/therion > _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion
