@function2000 Same problem! Did you solve it?

ZNBmm commented 4 years ago

MIUI scan code has no result, error Access denied finding property "vendor.camera.aux.packagelist" is reported, Huawei, iOS are normal

jacksun0124 commented 4 years ago

Temp. solution:

  1. Downgrade package from 3.0.1 to 2.0.2;
  2. Change this: await BarcodeScanner.scan().then((res) => barcode = res.rawContent); to this: await BarcodeScanner.scan().then((res) => barcode = res); 3 change this: if (e.code == BarcodeScanner.cameraAccessDenied) { to this: if (e.code == "PERMISSION_NOT_GRANTED") {

It's not a perfect solution, but it works on my app.
