How do I get a list of the ports which belong to preconfigured firewall-cmd services?

I want to open the following ports in my CentOS 7 firewall:
UDP 137 (NetBIOS Name Service)
UDP 138 (NetBIOS Datagram Service)
TCP 139 (NetBIOS Session Service)
TCP 445 (SMB)
I can guess that the services names include samba includes TCP 445 but I don't know if the other ports have a service name preconfigured.
I can list supported services with:
$ firewall-cmd --get-services
But this doesn't tell me what ports are configured with the services.
Is there a way to list what ports belong to these services so that I can grep for the one that I need?

The option you are looking for is--info-service. It wants the service name, tough. So, in order to get ports for many services, looking at service definition files as in Ulrich Schwarz's answer is probably more handy.

You can find the xml files this information is stored in in /usr/lib/firewalld/services/ (for distro-managed services) and/or /etc/firewalld/services/ for your own user-defined services.
For example, samba.xml reads (on my centos7):
<?xml version="1.0" encoding="utf-8"?>
<service>
<short>Samba</short>
<description>This option allows you to access and participate in Windows file and printer sharing networks. You need the samba package installed for this option to be useful.</description>
<port protocol="udp" port="137"/>
<port protocol="udp" port="138"/>
<port protocol="tcp" port="139"/>
<port protocol="tcp" port="445"/>
<module name="nf_conntrack_netbios_ns"/>
</service>
so it's easy to spot what ports are enabled by this service.
