Congrats on the launch. Ive switched from webflow to flutter for the website Im building (for my startup project). Flutter is awesome (though I still "wonder what the result is gonna be" but way less than with css) and I believe youre betting on a great horse. I dont know if youve noticed but when you browse a flutter website with chrome on a desktop computer, it offers you to install the app natively! Like you said: super cross-platform. Initially I was using webflow because I dont understand a thing to css and I find the paradigm sux overall. But then as a consequence webflow isnt my taste as well. I was building my android app with flutter and I thought I should just do the website with it as well. Best of luck, I think youre a hot startup. Ps: maybe you should consider to market it for website as well, not only apps (sry if you do already). Im no expert to say it will be convincing for this end but Im never going back to html5 and its derivative frameworks lemme tell you that :)
