- upgrade gradle to 7.4
- upgrade ext.kotlin_version to '1.6.10'
- change android -> build.gradle -> buildscript & allprojects jcenter() to mavenCentral()

Had to delete pubspec.lock
run flutter clean
run flutter pub get
extra step, might help you:
flutter pub upgrade
Upgraded dart version to 2.17 in pubspec also.
Fixed on the warning in cached network image, by removing the ? checks in the warning. The package will be updated by the maintainers, there already is 5 pull requests for the fix, can check here.
for iOS, had to delete podfile.lock also and run pod install --repo-update
Fixed things and compiled without warnings for iOS and Android.
