I am using an app of ionic-5 and capacitor-3,
I can use bar code to scan now
These is the plugin what i use for bar code scan
@ionic-native/barcode-scanner
phonegap-plugin-barcodescanner
But using the above plugin I can’t achieve QR code scanning
I want to know if ionic-5 and capacitor-3 can do QR scanning
Which plugins should i use
You can use version 2 of this plugin
(version 3 is for Capacitor 4)
Hi Ionic’s julio-ionic
I tried this plugin and it really works, but he has a conflict with the plugin I use now when I use it at the same time.
This is what I already have：
@ionic-native/barcode-scanner
phonegap-plugin-barcodescanner
This is what I’m going to add
@capacitor-community/barcode-scanner
When I built them, they seemed to produce the same jar file
How can i solve this problem?

You’ll have to uninstall one of them.
Both of them support QR and barcode.
