why sometime result is upcE ?

[yogithesymbian]

My QRCode result QR 1 = BarcodeFormat.upcE QR 2 = BarcodeFormat.qrcode

can anyone tell me why sometime the result its not QRCode ? what i save is aes-256-cbc encryption text what i encrypt is uuid from "uuidv4": "^6.2.12", date time , and 3 other value / secret (short data)

i know the result its different when i tried to scanning from qr_code_scanner: ^0.5.2 flutter dependency https://pub.dev so 1 of 10 qrcode have broken and cant to scanning because its not QRCode but its upcE.

when i scanning 1 of data:

[log] qrcode format : BarcodeFormat.upcE
[log] qrcode data : 13417680 // its not my encryption text (aes-256-cbc) // unexpected

other data its valid 9 of 10 data

[log] qrcode format : BarcodeFormat.qrcode
I/flutter (12777): qrcode data decryption : *******secret*****
[log] qrcode data : hILYH7JI/3Bch8f8x6NN6EyksfL/Kho8swerYC4c6gk08R01N+behSEO0F2IcucBhq9c5cll7ex23cGrqaKn3h3Iw5RsPeNhlVddSnKZ6WsLiHS62ZBWsx06oeRqlzXJBnYI0B8GWm20K7uvpTduGQ3vCVWgeSjXkvGV+G9QQLibKMIGD/mhHBWHx3jrlsGI
