[Bug] The method 'markNeedsBuild' was called on null.

[ryanhz]

Describe the bug Not a critical issue, It is from sentry report:

NoSuchMethodError: The method 'markNeedsBuild' was called on null.
Receiver: null
Tried calling: markNeedsBuild()
framework.dart in State.setState at line 1264
chat_view.dart in DashChatState.widgetBuilt.<fn>.<fn> at line 423
Called from: zone.dart in _rootRun
ticker.dart in TickerFuture.whenCompleteOrCancel.thunk at line 399
Called from: timer_impl.dart in _Timer._runTimers

To Reproduce I don't really how to reproduce this, but this issue is quite common. I guess it is the user send message then navigate away from that page.

Expected behavior A clear and concise description of what you expected to happen. No error
