You should update the package 'flutter_svg' from 0.18.1 to 0.19.3 and it should solve your issue, it happens because of the 'nullOk' parameter that was removed in Flutter 2. You can read about it here: https://flutter.dev/docs/release/breaking-changes/eliminating-nullok-parameters
I found this solution and it worked for me
