Cached network image is throwing errors after using non-nullable in flutter - flutter

Question

Currently using Non Nullable for flutter, all the dependencies work fine except for cached_network_image.
My pubspec.yaml:
environment:
sdk: ">=2.10.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
cached_network_image: ^2.3.3
In my launch.json for VS code, I've included args:
"--enable-experiment=non-nullable",
"--no-sound-null-safety",
I've also added analysis_options.yaml:
analyzer:
enable-experiment:
- non-nullable
The errors I'm getting:

cached_network_image doesn't seem to have a null safe release. If anyone has encountered this or has insights, please let me know. Greatly appreciated!

Remove Full Key of 'args':
"args": [
"--enable-experiment=non-nullable",
"--no-sound-null-safety",
]
