add-to-app create an explicit example of launching a flutter screen with prepopulated data

[xster]

This is pretty much what you have already, but right before presenting a flutter view, invoke a channel message to send something.

Good Idea. This can also be included in something we want to achieve through the new "platform channel sample app" idea. @RedBrogdon what do you think?

[xster]

That's a good idea. We can do a 2 in 1 of showing pigeon and doing data passing on launch/dismiss in one demo.

@xster i would like to know how to approach to solving this issue. If possible !

It's on Android only currently but there's a demo to that effect in https://github.com/flutter/samples/tree/master/add_to_app#android_books-and-ios_books-todo
