Flutterfire: 🐛 [firebase_ml_vision] Getting inconsistent result while scanning bar code
Describe the bug
Im trying out the example code provided in the firebase_ml_vision and when i scan the bar code it gives displayValue as
"{"typeNumber": "0", "errorCode": "3", "version": "65"}", rarely it gives the correct displayValue, for the same barcode it sometime gives correct output and sometimes with the above error code
I have attached the image for reference
Steps to reproduce
Steps to reproduce the behavior:
- Clone the example app for firebase_ml_vision provided in the official Flutterfire repo.
- In main.dart file Initialise MaterialBarcodeScanner with height:400 and width:300
i.e
... const MaterialBarcodeScanner( validRectangle: Rectangle(height: 400, width: 300), ), ... - Setup the firebase project in the console.
- Once the app starts, select MaterialBarcodeScanner in the homepage.
- Generate a barcode online with default options.
- App shows wrong barcode value with error code.
Expected behavior
App should show correct barcode value
