Flutter web offline support

[AMuellerAtAHS]

What information is missing?

There should be a notice that flutter web canvaskit needs an internet connection to load canvaskit.wasm / canvaskit.js. Also it would be nice if there is a short description about how to bundle the canvaskit to use it offline.

How would you like us to fix this problem?

• [ ] Add notice to web build and web release explanation sites.
• [ ] Add description how to bundle canvaskit to FAQ or Web renderers

flutter build web --dart-define=FLUTTER_WEB_CANVASKIT_URL=/canvaskit/
