- Here is my code on the robot side:

Robot.cpp

static std::shared_ptr<NetworkTable> table;
NetworkTable::SetIPAddress("10.20.53.21");
NetworkTable::SetClientMode();
NetworkTable::Initialize();
table = NetworkTable::GetTable("vision");

GoalAlign.cpp

distanceToCenter = Robot::table->GetNumber("center", 0.0);

- On the raspberry pi side

std::shared_ptr<NetworkTable> visionTable;
visionTable = NetworkTable::GetTable("vision");
visionTable->PutNumber("center", distanceCenter);

I'm not sure if I am doing this correctly. I'm not getting any errors but I'm not getting any values either.

Your robot needs to be the server. There's actually code in some of the top-level classes which preconfigures it to be a server before it enters your code, and that's what the driver station dashboards etc assume. The raspberry pi should be set up as the client. So you should move the

NetworkTable::SetIPAddress("10.20.53.21");
NetworkTable::SetClientMode();
NetworkTable::Initialize();

lines to your raspberry pi, changing the IP address to the robot IP (or robot name, e.g. "roborio-2053-frc.local"). Using NetworkTable::SetTeam(2053) should do the latter for you.
