Running/Debugging Flutter app very slow after upgrading to latest SDK version 1.20.4
4,657
Solution 1
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.
Solution 2

I'm facing this problem after upgrading to latest stable version 1.20.4 Earlier I was using Flutter 1.12.13+hotfix.5 and debug/run speed was good enough. Is anyone else also facing this issue? Or could anyone help by suggesting some solutions or reasons as to why this is happening? I am using a Windows 10 machine. Running
flutter doctor -v
yields the following output• Flutter version 1.20.4 at D:\flutter • Framework revision fba99f6cf9 (8 days ago), 2020-09-14 15:32:52 -0700 • Engine revision d1bc06f032 • Dart version 2.9.2 [√] Android toolchain - develop for Android devices (Android SDK version 29.0.2) • Android SDK at C:\Users\amani\AppData\Local\Android\Sdk • Platform android-29, build-tools 29.0.2 • ANDROID_HOME = C:\Users\amani\AppData\Local\Android\Sdk • Java binary at: C:\Program Files\Android\Android Studio\jre\bin\java • Java version OpenJDK Runtime Environment (build 1.8.0_202-release-1483-b03) • All Android licenses accepted.

Fatiha IMOUSSAINE about 3 yearsthe speed depends mainly on your hardware specifications , it's true that it may be a temporary solution but better than spend all your time , i search for a solution but almost every one was doing this , and this worked for me as well

Amani Saaduddin about 3 yearsI do understand that, and finally it's solved. It seems that on running flutter upgrade caused some changes to the existing SDK on the system which resulted to the issue.
