Hi, @Anonymous
Yes. You can deploy the Flutter Web App on your SWA.
Static Web Apps only do static hosting, so it doesn't depend on the front-end framework.
If you need server-side Flutter, you can additionally select and deploy a hosting model or use Azure Functions. Although not mentioned in this thread, Azure Functions does not support DART.
There is no direct deployment method for Static Web Apps such as FTP, and it is necessary to integrate the deployment pipeline such as GitHub.
You can probably build a GitHub workflow that integrates with flutter build web
