Visual Studio Code – Target of URI Doesn’t Exist

Possible Fixes for VS Code Not Detecting Flutter/Dart

1. VS Code Extension Issues

• Restart VS Code – Simple but effective.
• Reload Window – Press Ctrl+Shift+P → type “Reload Window”.
• Disable/Re-enable Extensions – Disable, then enable the Dart & Flutter extensions.
• Update Extensions – Check for updates in Extensions (Ctrl+Shift+X).

2. Flutter SDK Issues

• Check Installation – Run flutter doctor for errors.
• Clean & Rebuild – Run flutter clean → flutter pub get.
• Fix SDK Cache – Try flutter pub cache repair.
• Reinstall Flutter – If all else fails, reinstall the Flutter SDK

3. Project-Specific Fixes

• Delete .dart_tool/ – Then run flutter pub get.
• Correct Project Location – Ensure VS Code is opening the right folder.
• Check Workspace – Avoid workspace conflicts by opening the project folder directly.

4. macOS-Specific Fixes

• File Permissions – If needed, run sudo flutter pub get.
• Xcode CLI Tools – Install via xcode-select –install.

Additional Debugging

• Run flutter doctor – Look for warnings/errors.
• Try a New Project – flutter create test_project → check if the issue persists.

If the problem continues, post:

1. flutter doctor output
2. pubspec.yaml contents
