Solved:Dart analyzer has terminated!

If you’ve upgraded your Flutter SDK but still encounter issues in VSCode, particularly when the Dart analyzer terminates, it might be due to permission errors. I faced similar challenges on macOS and tried numerous solutions. Finally, after several hours, I found a fix. Please follow the instructions below and enter the provided commands into your terminal. I’m confident this will resolve your problem.”

Note: It would be helpful to include the actual commands or instructions after this introduction.

Actually the error is like this

Oops; flutter has exited unexpectedly: "PathAccessException: Cannot open file, path = '/Users/ahmadreza/.dart-tool/dart-flutter-telemetry-session.json' (OS Error: Permission denied, errno = 13)".
A crash report has been written to /Users/ahmadreza/Documents/development/time_waster/flutter_03.log
Unhandled exception:
PathAccessException: Cannot open file, path = '/Users/ahmadreza/.dart-tool/dart-flutter-telemetry-session.json' (OS Error: Permission denied, errno = 13)

The error message you provided suggests that Flutter is trying to access a file and does not have the necessary permissions. This is typically due to file ownership or permission settings.

Here’s how you can address this issue on a macOS:

Check File Permissions: First, use the terminal to check the file permissions:

ls -l /Users/ahmadreza/.dart-tool/dart-flutter-telemetry-session.json

This will provide information on the file ownership and permissions.

Change Ownership: If the file is owned by a different user (not ahmadreza), you can change its ownership using the chown command:

sudo chown ahmadreza:staff /Users/ahmadreza/.dart-tool/dart-flutter-telemetry-session.json

Change Permissions: If the permissions of the file are too restrictive, you can modify them using the chmod command:

sudo chmod u+rw /Users/ahmadreza/.dart-tool/dart-flutter-telemetry-session.json

This grants read and write permissions to the file owner.

Delete the File: If you still face issues, consider deleting the file, as Flutter might recreate it if needed:

rm /Users/ahmadreza/.dart-tool/dart-flutter-telemetry-session.json

Check and Repair Disk Permissions: Sometimes, disk permissions can get mixed up on macOS, leading to unexpected permission issues.

• Open Disk Utility (You can find it using Spotlight with Command + Space and then typing "Disk Utility").
• Choose your system volume (usually named “Macintosh HD” unless you’ve renamed it).
• Click on First Aid at the top and then run it. This process will check and repair permissions on your system.

Run Flutter with Elevated Privileges: As a last resort, you can run Flutter with elevated privileges using the sudo command:

sudo flutter [your command]

However, use this method with caution, as running operations with superuser privileges can have unintended side effects if you’re not sure what you’re doing.

After trying these steps, try your Flutter operation again. If you continue to face issues, provide more context or check Flutter’s official documentation and forums for more specific solutions.

Finally: delete cache folder in Flutter/bin and then

flutter clean
flutter run

I hope you find this helpful. If so, please give it a clap me!”
