Barcode scanning does not start on some non-Google Android devices (Huawei, Rhino, etc.)

[MahmoudMm]

Description:
First, thanks for the great work on this package! I am using @capacitor-mlkit/barcode-scanning in a production application, and it works well on most Android devices. However, I have noticed that on some phones, particularly those without Google services (such as Huawei and Rhino devices), the scanning process does not start.

Unfortunately, I don't have direct access to these devices for debugging, but multiple users have reported the issue. The camera just refuse to open in any way, without clear error message.

Steps to Reproduce:

Install @capacitor-mlkit/barcode-scanning on a device without Google services (e.g., Huawei or Rhino).
Open the barcode scanner in the app.
No camera opened.

Expected Behavior:

The scanner should function normally on all Android devices, even those without Google services.

Observed Behavior:

On certain non-Google Android devices, the camera does not open

Additional Information:

Capacitor Version: 7
@capacitor-mlkit/barcode-scanning Version: 7.1
Device Models: Huawei, Rhino (possibly more)

Possible Cause & Questions:

Does this package rely on Google ML Kit services that require Google Play Services?
If so, is there a way to provide an alternative implementation for non-Google devices?
Are there any logs or debugging steps that could help diagnose the issue?

Thanks in advance for any help or guidance!

Thank you for reaching out. At first glance, it looks like you are using the scan(...) method that only works for Android devices with Google Play Service. You should therefore definitely use the startScan(...) method, which supports all Android devices. If this does not help, please create an official bug report via the issues section since we need more information to be able to help you.
