Problem with the connection between postgresql and flutter

Question

So I'm developing a Flutter project that interact with PostgreSQL Database with Dart and I have a problem with the connection between PostgreSQL and Flutter.

Any ideas why I'm getting this kind of error:

The most likely reason is that the firewall on 10.0.0.2 is blocking inbound connections or the postgres server is only listening on localhost. As an aside about your Flutter code, you obviously must not perform any database operations in build as they all take time to finish and build must not wait for anything. When calling connection.open() you should await the result, which means you need to do that somewhere you can make async. This is one of the topics about Flutter that confuses some people initially, but since it is so fundamental there's lots of good articles about it. — Richard Heap

So thankfully I found the error. I was pointing at 10.0.0.2, but I had to put 10.0.2.2.
