Due to min v1.5 sdk plugin needs, I use flutter upgrade, but since I can't use command ... I have bash command not found,

I tried manually download 1.5 sdk and replace previous folder, when I use flutter doctor He say I have 1.2.1 ... I tried to re-upgrade but I have this error :

Your flutter checkout has local changes that would be erased by upgrading. If you want to keep these changes, it is
recommended that you stash them via "git stash" or else commit the changes to a local branch. If it is okay to remove
local changes, then re-run this command with --force.




C:\Users\utilisateur>flutter doctor

  • flutter doctor is ok 1.5 but it's now android studio .. I have change the path of flutter sdk but I have Warning! This package referenced a Flutter repository via the .packages file that is no longer available. The repository from which the 'flutter' tool is currently executing will be used instead. running Flutter tool: C:\flutter previous reference : C:\Users\utilisateur\flutter This can happen if you deleted or moved your copy of the Flutter repository, or if it was on a volume that is no longer mounted or has been mounted at a different location. – Nitneuq Jun 20 '19 at 08:46
  • I think it's because at the creation of the projet I add sdk path, but now it change, it's possible to change this if it's this ? – Nitneuq Jun 20 '19 at 08:49

In my case Flutter had unstaged changes (since it uses git), so I needed to stash or reset it to be able to upgrade it.

Go to flutter's path and:

# cd flutter_path/
git add -A
git reset --hard

Alternatively, you can use --force to upgrade it anyway.

flutter upgrade --force

Windows | iOS

Delete the old Flutter SDK folder you created. Then follow the steps illustrated here to point Android Studio to the new Flutter SDK installation. enter image description here

I encountered the same problem. This probably occurred because I have my flutter SDK installed in the E:\ directory rather than default C:\ directory. This is how I solved it,

1: Check where your Flutter Sdk is present. You can do this by creating a "New project->Flutter->Flutter Sdk" (This works if you have the flutter Sdk installed and configured, If you don't have it installed you can click on install Sdk option in the same "new Project->Flutter" window).

2: Then open Terminal by going to bottom right corner of you IDE and then clicking on terminal.

3: Change your directory to the flutter sdk's bin location by Typing "cd _yourSdkLocation\bin". Here replace "_yourSdkLocation" with the directory address where your flutter Sdk is present.

4: Then run "flutter upgrade --force"

In Terminal, use command

  • and then run ,

To remove changes in flutter directory, It will upgrade to recent flutter version
