[6bd5f8b2][Logcat] Stopping logcat capture

I have tried below things as teardown() to stop appium_process:

if self.appium_process is not None and self.appium_process.poll() is None:
            self.appium_process.terminate()
            self.appium_process.wait(timeout=10)  # Set a timeout to avoid hanging
            self.appium_process.kill()
            logger.info("Appium server stopped")
        else:
            logger.info("Appium server is not running")

However, I am using automationName as Flutter and context set to FLUTTER then if it does not find flutter element because of not being present on screen/disappeared/app crash any or this happens and try to termminate all appium process I do not receive proper shut down of appium server and it blocks all my tests in the queue hanging. For context with NATIVE_APP it works well.
these are my capabilities:

"platformName": "Android", "platformVersion": "13.0", "deviceName": "emulator-5554", "automationName": "Flutter", "retryBackoffTime": 500, "newCommandTimeout": 300
