Add guide to writing accessible Flutter applications

[chunhtai]

What information is missing?

We don't have much resource on how to write an accessible flutter app

How would you like us to fix this problem?

here are something we can consider adding.

1. a cookbook demonstrates how to use Semantics widgets to achieve different goals.
2. some tutorial videos similar to 1
3. add a page introduction to flutter accessibility, and tools we provide.

This feedback was coming from internal customer. They were looking for code sample on how to actually implement the app using Semantics widget. While most of the built-in widget works out of box, customer would still need to do some manual tweaks. That would involve using the Semantics widget to add additional information.

The page you linked seems to focus on testing and tooling.
