I found an awesome Dart-based open-source project.
1. Dartblaze for writing Firebase Functions in pure Dart, it could be awesome i.e. to share utility functions between client-side Flutter and server-side (Cloud Functions) Dartpad source
DISCLAIMER: This project still is not an production-ready

Jasp - even more awesome, ability to create classic HTML websites in Dart, with similar concepts as Flutter but compared to the Flutter web, it is fast with the possibility for a Lighthouse score of 100 comparing to the Flutter web which is extremely fast in WASM but waiting for the first pixel is long

I am sure that with small adjustments FlutterFlow Editor can easily export Jasper-adjusted Dart source and gives the ability to deploy as a standalone website, which is fast as Next.js, Astro or any Webflow page.
But also with the Jaspr Flutter Embbeding component, it can load any Flutter component as Lazy loaded, my current workaround is to embed as an external <iframe> in any other HTML.
