QUESTION

how can i increment the count of same type of box if it gets the same type of box after scanning the qrcode?

Asked 2021-Oct-13 at 14:10

Im using the qrcode scanner to detect and decode and it decodes the output properly. Here im using the "text" as the decoded output of qrcode. If It gets same type of box like APPLE,it must increment the apple_count to 1. by using this code i only get "1" for apple_count . I think the problem may be because of loop but Im not able to solve it.Please help me.Thankyou
