BUG: Compile on Android, plugin uses web implementation if gradle minifyEnabled is true

[zNoobs]

Hi, I'm using Ionic 5 Angular with Capacitor.

"@angular/core": "~11.2.0",
"@ionic/angular": "^5.5.2",
"@ionic-native/core": "^5.31.1",
"@capacitor-community/barcode-scanner": "^1.2.1",
"@capacitor-community/camera-preview": "^2.0.0-beta.0",
"@capacitor/android": "^2.4.6",
 "@capacitor/core": "2.4.6",

Smartphone (please complete the following information):

• Device: Xiaomi Mi A1
• OS: Android 9

On Android, when I compile with minifyEnable to true, the plugin uses the web implementation on my phone (so no flash and no flip), here a part of my build.gradle (of the folder app):

android {
    buildTypes {
        release {
          minifyEnabled true
        }
    }
}

If I set minifyEnable to false, the plugin uses the native implementation. Why does this happen?
