Running/Debugging Flutter app very slow after upgrading to latest SDK version 1.20.4


i had a simular issue , for me i return to the previous stable version and everything goes good ,run flutter downgrade to return to the previous fluter version install on your machine


Solved the issue by deleting Flutter SDK and then replacing it with newly downloaded SDK.It seems that upgrade caused some files to get corrupted in the SDK directory.
