Turning on and off the flash is not working on Android 11

[TheKamranUllah]

Description of the problem:

if (isFlashOn) {
mCodeScanner!!.isFlashEnabled = false
isFlashOn = false
Toast.makeText(getActivity(), "False", Toast.LENGTH_LONG).show();
} else {
mCodeScanner!!.isFlashEnabled = true
isFlashOn = true
Toast.makeText(getActivity(), "True", Toast.LENGTH_LONG).show();
}
The above code makes no sense for turning flash light on/off

Which library version are you using? E.g. 3.2.0.
Library version: 3.2.1'

Which phone/tablet are you using, and which Android version does it run? (e.g. Samsung Galaxy S5,
Android 5.0)
I am using Redmi 9 with Android version 11

Does the same happen on other devices or an emulator?
Works fine on Android 10 and Android 6 I checked on these two.

Can you reproduce the issue in the sample project included with the library? If not, can you
provide your own sample project or sample code that produces this error?

Provided above in the problem description

In the case of an error do you have a stack trace or adb logs?

Using the sample project, flash works for me on Android 11.

The above code does not show how it is trying to turn the flash on or off.

See this code for a working sample:
