Sounds exciting. I’m still on Windows I’m afraid, so would like to try the web app while there is no Windows install.
I’m missing something – all I get on Brave, Chrome and Edge Browsers is a blank white screen.
Uncaught ReferenceError: _flutter is not defined at webapp/:51:7 <script src="flutter.js" defer></script> ... <script> window.addEventListener('load', function (ev) { // Download main.dart.js _flutter.loader... <--------- Error happens here _flutter does not exist in the global scope. I have not looked too far into why, because the flutter code has been minified, and is very difficult to read as a result. You do not need to minify code. Your server will support gzipping and other compression anyway, and that can do a better job than a minifier - your server sends things compressed using brotli already, which is extremely efficient at compression. The bonus is that other people will then be able to read the code and help you with it. I don't know if this is the problem, but in flutter.js, the very first line performs a sniff that is bound to go wrong in some browsers, since it thinks Google and "Edg/" are the only browser vendors using Chromium, which is absolutely not the case. There are several other vendors using Chromium, and they have a right to use their own vendor string. Sniffing like that is very bad form, since it requires browser vendors to falsify information in order to make your app work correctly. (I work for one of those browser vendors, and we are forced to pretend our product is made by Google, which it isn't. However, many other vendors quite rightfully want to identify themselves correctly.) Use object detection instead. The subsequent code uses object detection with its typeof checks - a more normal method would be: if( window.ImageDecoder ) { //do a thing that uses it.
