If the address is `""` then an available address is automatically
picked.
```
// Network#allocate_tcp_port
if listen_address.is_empty() {
// If listen address is empty, find us a port iteratively
let port = self.find_available_tcp_port(5150)?;
let ip_addrs = available_unspecified_addresses();
Ok((port, ip_addrs))
} else {
// ...
}
```
Here was the error.

Dart, as of version 2.1.1, has a linter rule called
'unnecessary_await_in_return', described as 'Avoid returning
an awaited expression when the expression type is assignable
to the function's return type'. This can be found at
https://dart.dev/tools/linter-rules/unnecessary_await_in_return
VSCode applied that linter rule automatically, and I am tired of
the warnings, so I'm submitting this. :)
Clippy also informed us that we can drop some of the clone calls.
