I assume that this is meant as a criticism, but Flash was quite good at easy-to-make portable graphical apps; they had massive security issues and some lack of polish, but there's a reason why Flash dominated its era. (Also, "Macromedia Flash for desktop" was already a thing, no?) So yeah, "Flash but modern and safe" would be a pretty strong selling point.
Flash remains the most productive UI development environment I have had over the past twenty years. Getting graphical apps working on all major platforms is a fabulous achievement by the Flutter folks.
I have no love for what Android has become and where Kotlin is going. The web today feels like a PDF...huge amounts of movement but not necessarily progress.
I hope more than anything that Flutter continues to gain traction. To my mind it is perfectly reasonable for next generation tech to write to the canvas with the latest widgets as long as there is good accessibility support.
