Allow users to create samples using flutter create. (#23584)
This adds flutter create --sample which allows users to execute a command which will create a working sample app from samples embedded in the API docs.
The command looks something like this:
flutter create --sample=chip.DeletableChipAttributes.onDeleted mysample
diff --git a/dev/snippets/config/skeletons/application.html b/dev/snippets/config/skeletons/application.html
