Could not find method buildFeatures() for arguments [] on object of type com.android.build.gradle.LibraryExtension

I added the package 'qr_code_scanner: ^0.5.1' into my pubspec.yaml.

Solution

    • stop project

    • delete the folder (C:\Flutter\flutter.pub-cache\hosted\pub.dartlang.org\qr_code_scanner- 0.5.1

    • change to version "qr_code_scanner: ^0.4.0",

    • run flutter pub get
