The solution for resolving the error [ERROR:flutter/runtime/dartvminitializer.cc(41)] where an unhandled exception of Bad state is encountered due to a listened-to stream is to properly handle the state of the stream listener.
This can be done by using the appropriate methods in the Stream class, such as pause(), resume(), and cancel(), to manage the listener's subscription to the stream.
Additionally, any relevant logic that depends on the state of the stream, such as updating UI elements or triggering other actions, should be contained within the listener's onData() or onError() callbacks, and any necessary checks should be performed to ensure that the stream is in the expected state before accessing its data.
Some other steps that can be taken to prevent this error include ensuring that the stream is properly initialized and that any resources associated with the stream are properly disposed of when they are no longer needed.
