i have tried some ways

  1. Flutter clean then pub get again
  2. delete pubspec.lock
  3. clean the .pub-cache
  4. upgrade gradle to 7.4
  5. upgrade ext.kotlin_version to '1.6.10'
  6. change android -> build.gradle -> buildscript & allprojects jcenter() to mavenCentral()
  7. upgrade Android Gradle Build version to the latest "classpath 'com.android.tools.build:gradle:7.1.3'"

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.
