Flutter: can't find dependency in pubspec.yaml

Question

I want to migrate dart null safety but there is one package that isnt ready for null safety yet. When execute flutter pub outdated --mode=null-safety it get this:

Package Name             Current  Upgradable  Resolvable  Latest

direct dependencies:
flutter_template_images  ✗4.0.0   ✗4.0.0      ✗4.0.0      ✗4.0.0

dev_dependencies: all support null safety.
You are already using the newest resolvable versions listed in the 'Resolvable' column.

The problem is the package flutter_template_images is not in my pubspec.yaml file so I cant delete it to migrate null safety. I dont know where this package comes from and I want to delete it but how can I find and delete this package?

I appreciate every answer!

This is my pubspec.yaml file:

# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
