Quasar FrameworkQuasar Framework

The only two programming languages I know are Python and Dart, I fall in love with Dart when I learned about the type safeness, ease of refactoring, and the help of the IDE. I have an idea for an app, a simple app, but I need SEO and server rendering, and I also want it to be available on all platforms. I can't use Flutter or Dart anymore because of that. I have been searching and looks like there is no way to avoid learning HTML and CSS for this. I want to use Supabase as BASS, at the moment I think that I have two options if I want to learn the least amount of things because of my lack of time available:

  1. Quasar Framework: They claim that I can do all the things I need, but I have to use JavaScript, and I am going to have all those bugs with a type-safe programming language avoidable. I guess I can use TypeScript?, but that means learning both, and I am not sure if I will be able to use 100% Typescript. Besides Vue.js, Node.js, etc.

  2. Blazor and .NET: There is MAUI with razor bindings in .Net now, and also a Blazor server. And as far as I can see, the transition from Dart to C# will be easy. I guess that I have to learn some Javascript here and there, but I have to less things I guess, am I wrong? But Blazor is a new technology, Vue is widely used.
