Error

The getter 'hasCameraPermission' isn't defined for the type 'MobileScannerState'.
Try importing the library that defines 'hasCameraPermission', correcting the name to the name of an existing getter, or defining a getter or field named 'hasCameraPermission'.

There is an error with the hasCameraPermission option in the idChangeAppLifeState method part in the official document. Which part should it be replaced with? Can you correct it?

Currently, I am checking with isInitialized option.

This getter is defined here: https://github.com/juliansteenbakker/mobile_scanner/blob/master/lib/src/objects/mobile_scanner_state.dart#L66

What version of mobile_scanner are you using? The getter was introduced in version 6.0.0, as stated in the changelog.

https://github.com/juliansteenbakker/mobile_scanner/blob/master/CHANGELOG.md#600

If you do not want to upgrade to that version, you can just do the check yourself, too.

For that, you'll need to check both isInitialized and error?.errorCode != MobileScannerErrorCode.permissionDenied

@hailuongsl97 I do not understand what problem your are encountering? You can use hasCameraPermission in didChangeAppLifecycleState, to determine if the controller should be started when the application is resumed.
See the example at https://github.com/juliansteenbakker/mobile_scanner/blob/master/example/lib/barcode_scanner_controller.dart#L62-L81

Or are you referring to a different issue?
