It shows clearly that Flutter for web is hot garbage. It is flaky (Safari on iOS 18, iPhone 15 Pro Max), it doesn’t let me select text or copy-paste anything. Rendering the UI in a Canvas works only for niche apps.
This implementation of Visual Basic 6 written in C# compiled to WebAssembly also works better in Chrome, Edge, and Firefox than it does in Safari: https://bandysc.github.io/AvaloniaVisualBasic6/
Safari must catch up.
