Idiom #25 Send a value to another thread

Share the string value "Alan" with an existing running process which will then display "Hello, Alan"

import "dart:isolate";
sendPort.send("value");

Ports are used for communicating between individually running isolates. The receiving isolate has created the corresponding receive-port and passed the send-port to this isolate.
declare

   task Greeter is
      entry Greet (Name : String);
   end Greeter;

   task body Greeter is
   begin

      accept Greet (Name : String) do
         Ada.Text_IO.Put_Line ("Hello, " & Name);
      end Greet;

   end Greeter;

begin
   Greeter.Greet ("Alan");
end;

This is called a rendez-vous in Ada. The caller is blocked until the Greet accept statement is completed.
