🐛 Bug Report: Realtime throws type 'Null' is not a subtype of type 'Map<dynamic, dynamic>' exception

[stnguyen90]

👟 Reproduction steps

1. Subscribe to a channel on Appwrite Cloud
2. Wait for the ping/pong heartbeat messages

👍 Expected behavior

No errors occur

👎 Actual Behavior

Error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: type 'Null' is not a subtype of type 'Map<dynamic, dynamic>'

This occurs because the pong message from the heartbeat ping does not contain the data property so the parsing of the message fails.
