tried flutter clean, flutter pub get this didn't worked. then i went for flutter pub upgrade --major-versions ... still shows the same error after flutter build apk

that happens sometimes because some issues wrong in the flutter sdk try to download the sdk again and replase with the current. or toggle the version with the FVM tool.
it will build with you and if you use for example 2.10.0 you can use also 2.10.3 it also will work.

[Flutter][APK]Dart snapshot generator failed with exit code -9

I had a Flutter app that was working just fine until today. I realized that the flutter build apk --release wasn't building the Flutter app with the latest code. Looked up on the internet.

try building your application with this flutter build apk --no-tree-shake-icons

There is an issue with icons in Flutter 2.10.0 which causes this error. I am assuming that you are using 2.10.0 version of Flutter.
This issue is resolved in Flutter 2.10.2. So, run Flutter upgrade in the terminal to solve the problem.

any chance you have hardcoded path in your build.gradle or somewhere else? C:\\Users is not a valid path on Codemagic builder machines because it uses macOS or Linux
