Hi,
pub get failed (1; Because xxx depends on qrcode ^1.0.5 which doesn't match any versions, version
solving failed.)

@SiriDx Any chance you could get the new version on pub.dev?

breaking change on minSdkVersion, from 16(current) to 24, by THIS PR, because com.journeyapps:zxing-android-embedded:4.1.0 change minSdkVersion to 24, can we just use com.journeyapps:zxing-android-embedded:3.6.0?

according to this
