How can I fix "Checking Dart SDK version... << was unexpected at this time" error in Flutter?

I've resolved this error with the below steps:

1. Go to C:\Users\{Name}\.gradle} - Delete the .gradle directory.

2. Then Download and install the same flutter and dart SDK version in some other location and set the environment variables.

   Example:

   Environment variables Before :

   ("D:\FlutterExtractedFiles\flutter\bin")
   ("D:\FlutterExtractedFiles\flutter\bin\cache\dart-sdk\bin")`
   

   Environment variables After :

   ("C:\edgedownloads\flutter_windows_v1.12.13+hotfix.8-stable\flutter\bin")
   ("C:\edgedownloads\flutter_windows_v1.12.13+hotfix.8-stable\flutter\bin\cache\dart-sdk\bin")
   

3. Then check the Android Studio event log

   

Flutter reinstalled worked for me..

• delete flutter folder in C directroy.

• make a src folder in C: directory.

• GoTo cmd and install flutter from official flutter github repoC:\src>git clone https://github.com/flutter/flutter.git -b stable

  https://flutter.dev/docs/get-started/install/windows

• run flutter doctor

• set env path.

• DONE

What worked in my case was deleting the .gradle file (C:\Users\USER.gradle) and reinstalling Flutter in another location and changing the PATH to it.

For me, the following steps resolved the problem:

1. Open cmd and run flutter doctor. (if there is an issue resolve them first.)
2. If not then change the flutter channel to dev. Whatever your channel is?. If this is the dev channel then change to master channel.
3. Again flutter doctor. If everything goes perfectly. then run your project. If it runs accordingly then again change to channel to stable.

you should try this

restart your pc and delete the flutter folder in C directory then reinstall flutter and run flutter doctor

I faced this error before, all I had to do was to:

1. Remove Flutter from my C directory.
2. Install Flutter from the official website.
3. Run Flutter doctor: flutter doctor

No need for changing the PATH or any further actions.

If it worked fine with you then you are all done!

I faced another error after it, related to the Dart SDK and solved it using this link

the key is to install Android SDK Command-line Tools, steps being: Open Android Studio Tools Menu, SDK Manager In the window that comes up there are inner panels, choose SDK Tools panel Tick Android SDK Command-line Tools Choose Apply button near the bottom of the window At that point, you will be prompted to accept the SDK license and the command line tools will be installed. Your license issue should now be resolved.

I've resolved this error by following these steps:

• Go to folder C:....\Flutter\
• Run this command: git reset --hard HEAD

This will restore the flutter SDK folder to its original state, so no need to reinstall the SDK.

If your using Intelij and get the << error and none of the above work.

Delete the .intelij folder in your project and reopen the folder in intelij.

I faced this problem too and I've solved it by downloading SDK file again.
