Error when user stay in silent dont possible refresh the widgets

[desenvolvedor-apanheidoexcel]

When the user remains silent, it generates a SpeechRecognitionError (onError listening) which destroys the widget tree and then it is not possible to update the view after the error.

I created a button with a microphone icon to start listening. When you click the button, the icon changes to indicating listening... When you finish listening with setState, the icon returns to start listening. But if the user doesn't say anything, a SpeechRecognitionError is generated which no longer calls setState because it destroys the widget tree.
