Straight from Google:
Warning: As of 1.9, web support is available as a tech preview. As web support hasn’t yet reached alpha, you can expect to experience crashes and missing features.
It seems to be fairly stable right now though, minus some bugs in the dartlang compiler that I encountered and other build issues.
The state management solution used in this app is Provider + ChangeNotifier. This solution is suggested as the pragmatic state management solution by Google. It's an easy and lightweight way to rebuild widgets only when state changes and have your UI respond to state changes reactively.
There's not much documentation on how to deploy a webapp built with Flutter since the web framework is still pre-alpha.
When you generate a Flutter web release build, you end up with a static site under build/web. The easiest way for me to deploy to Heroku was to create a Docker container which copies the static web files over and starts an NGINX server.
See the Dockerfile and the basic build script for more details.
The project includes basic widget tests and unit tests. It also includes static analysis using the pedantic package.
