I have tried:
flutter clean, deleted pubspec.lock and flutter pub cache repair to get rid of cache and reinstall packages but nothing.
flutter downgrade, got the same error.
Fresh reinstall of flutter, same thing.
Fresh git clone of the project, nothing.
Any hints?

Maybe you are getting errors because of jcenter. Follow the link and switch to mavenCenteral.

This is probably because the flutter SDK is in a different directory than your old machine. Checkout this answer.

Base from the error, the NDK build in your machine can't be used. One way to resolve this issue is by deleting the current NDK and have Flutter download a new NDK build. Head over to the NDK path provided in the error and delete ndk-bundle folder, then run flutter clean in the terminal. Running the app again should automatically run flutter pub get to rebuild all the references and dependencies.

How can I fix this issue?

This was happened due to a pub cache conflict. The problem was fixed after executing the following command in the terminal.
dart pub cache repair
dart pub get
dart pub upgrade

I tried your solution but it does not work for me. My solution is update compileSdkVersion to 30 in my app/build.gradle.

Update the flutter toast version to latest fluttertoast version in dependencies in pubspec.yaml . It worked for me.

I got the same error. Tried updating compileSdkVersion. Didn't work for me. This solved my problem.
pubspec.yaml -->> pub upgrade
Change fluttertoast version to latest
Pub get
Run...
