Open Vatsa0408 opened this issue 2 years ago • 3 comments

QR Scanner not scanning the QR Code for the second time.

Device Specifications

  • Flutter SDK version:- 3.0.1
  • Mobile Scanner version:- 2.0.0
  • minSDKVersion:- 21
  • CompileSDKVersion:- 32

Description

The mobile scanner will work for the first time. Once the QR code is scanned for the first time, the camera view will appear white for the second time onwards.

I have attached the error log

I am also attaching the UI when I want to scan the QR code for the second time image

The image below is obtained when I want to scan the QR code for the first time image

Kindly let me know about the solution for the above error

It is possible to rescan a QR Code simply setting allowDuplicates: true, but this cause a lot of fired event that you need to manage with some very bad implementations..

In my opinion we are looking for some code that reset the "scanned code memory" once for example controller.stop() is called. In this way the developer can simply call controller.stop() once identified the QR Code in order to executed the wanted logic, once controller.start() is called the "scanned code memory" will be erased giving user the possibility to rescan the same QR Code.

Looking at the repo code seems that all the "magic" is done by lastScanned string in the MobileScanner widget. @juliansteenbakker can it be an idea to move this variable in the controller class and manage it with the stop() or a new method to reset it? In this way the developer can simply decide if a QR Code can be newly scanned without allowDuplicates: true.

I have the same problem but its occurs even if i block the device screen when the camera is open

Since there has been lots of updates, please check with latest version 3.0.0-beta.4 and comment if this issue still exists.

juliansteenbakker avatar Dec 13 '22 20:12 juliansteenbakker

I updated to version 3.0.0-beta.4 and the camera view is visible now but scanning seems to stop working. We have the MobileScanner in a widget that needs to be toggled to show the scanner button. Toggling that widget on and off and on again makes it work. It was the same in version 2.
