Hi @ravindraguptacapgemini, Can you provide a minimal repro which demonstrates the issue?

Hi @ravindraguptacapgemini

Thank you for bringing up the issue. I have tested the @pushpendersingh/react-native-scanner library on both React Native versions 0.75.3 and 0.76.0. After thorough debugging, I can confirm that the library is functioning as expected without any issues in these versions.

If you'd like to test it yourself, please try the example provided in the example folder. The example has been upgraded to React Native 0.76.0 and is working fine. If you need to test the library on version 0.75.3, you can find the relevant example in the example/0.75.3 branch.

Please feel free to reach out if you have any further questions or need additional assistance. For now, I am closing this issue.

Best regards,

@pushpender-singh-ap okay let me check it again, I have few more changes in my local repo.
Can you please let me know, why we need to use Command
Commands.releaseCamera(cameraRef.current);
rather calling the methods directly on the ref
cameraRef.current.releaseCamera();

Hi @ravindraguptacapgemini

It’s essential to use Commands.releaseCamera(cameraRef.current) instead of calling cameraRef.current.releaseCamera() directly because the Commands object utilizes React Native's code generation system for native commands. This approach ensures that the command is dispatched correctly to the native layer, maintaining proper interaction between the JavaScript and native modules.

@pushpender-singh-ap there is a definite crash when opening camera.
I have found it that it's happening due to the API Validation under diagnostics settings in scheme

Currently, after disabling this option prevents crash. So we have a workaround but I am not sure what will be the impacts after disabling this option.

Hi @ravindraguptacapgemini

Thank you for the update. I'm not sure why you're experiencing this issue, as everything works fine on my end. I’ve tested the library in both React Native versions 0.75.3 and 0.76, with the API Validation enabled, and I haven’t encountered any crashes.

Have you had a chance to test the example provided in the example folder? It could help identify if the issue is specific to your project setup.

Please let me know if you need further assistance or guidance in troubleshooting this.
