Can I get a code of this example or similar examples. Please its urgent I have to perform testing so I need some good examples

The numbers in that blog series correspond to the names of the intro projects. So for tutorial 7, you can get the source using:

daml new intro7 --template daml-intro-7

I didn’t get it. From where?

Run the command I specified above and then you will have a directory called intro7 containing the code.

Thanks. Its working but I tried to generate its dot file using this command daml damlc visual intro7-1.0.0.dr --dot but unable to do. The error is “invalid argument visual”

daml damlc visual no longer exists. It was only a labs feature and not enough people found it useful so it has been removed.
