Connection cannot be closed about redis-dart HOT 2 CLOSED

I figured out the reason now.

Reason

1. I didn't figure out what send_object might return (a value or a null)
2. I didn't use the try-catch clause in the async code block so I didn't see any error report.
3. In my case, send_object executes the GET command and cannot get any matched key so it returns null. Obviously, a null cannot be assigned to a String variable.

Solution

change

String jobName = await cmd.send_object([
    "GET",
    "key",
  ]);

To

dynamic jobName = await cmd.send_object([
    "GET",
    "key",
  ]);

and check whether jobName is null.

Hi.

Can you provide more info about where your code gets stuck?
In case this code executes, but is not stucked (runs trough close()) I suspect, there must be some other operation that opens, but does not close connection.

Regarding open/close I have just pushed test designed in similar fassion to what you have just described 23af8c6. This test runs as expected (it pass), but feel free to modify, so we can learn, if we have indeed bug in this libraray.

Kind regards, Luka
