Possible solutions to what might occur:

Pay attention to indentation in your pubspec.yaml file.
Make sure that you don't have any error on dependency version.
Make sure that you run flutter pub get after adding dependency
Probably it is not documented that you have to add following permission to Android manifest file:

<uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.FLASHLIGHT" />
Sometimes it might be needed to clean cache and run the project again by using flutter clean && flutter run command on terminal.
