if you getting this error Flutter Build Error: Process 'command 'E:\Flutter Apps\flutter\bin\flutter.bat'' finished with non-zero exit value 1
then do this :-
I had the same problem after this command flutter upgrade and upgrading from V 1.22 to V 1.27.
Exactly what I did, I went to pubspec.yaml then pub-get & pub-upgrde I found there's many outdated packages then I tried pub-outdated and the AS failed to upgrade it, the it's suggests to me to run this command flutter pub upgrade --major-versions and I saw that it's successfully downloaded and installed outdated packages, Then I do Invalided Caches & restarted AS because I found it's cached about 5GB on C partition, and finally I run the app normally again without any problems.
after this run flutter run or flutter run --no-sound-null-safety
