Code 128 doesn't work in Android

[anthonycmeow]

Code 128 barcode can be generated in Android, however, it looks strange and can not be scanned successfully. In iOS Code 128 is working well, could you take a look? Thanks.

Hello iHunterX,

The below screenshot is from Android emulator, the barcode generated can't be scanned. The same pic in Android device also. However, it's working well on iOS.
My environment is 1.12.13_hotfix8, old flutter version also has this problem.
Attached my code below, feel free to let me know if you need more information, thanks.

BarcodeGenerator( witdth: ScreenUtil().setWidth(260 * 3), height: ScreenUtil().setHeight(60 * 3), backgroundColor: Colors.white, fromString: "123131313123131312313", codeType: BarCodeType.kBarcodeFormatCode128, ),

@anthonycmeow I faced the same issue- The problem is the widthxheight is hard coded in the BarcodeView.kt file to be 1000 x 1000 (or in essence a square), ..

2D barcodes are squares, CODE_128 is a rectangle.
Change the height to be 250 and you should be good.

I added a utility to check if it is a 2d barcode or not, and if it is, use 500x500, otherwise use 1000x250
