Run/Test Mode fails - git clone error on FlutterFlow's own dropdown_button2 dependency (exit code 69)

[maxdemarini-AnimalAlert]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

Run Mode and Test Mode both fail consistently (multiple retries, fresh sessions) with: 'flutter pub get failed with exit code 69'. Build output shows: Git error. Command: git clone --mirror https://github.com/FlutterFlow/dropdown_button2.git / fatal: could not read Username for 'https://github.com': No such device or address / exit code: 128. The dropdown_button2 dependency (source: git) appears under Settings > Pubspec > FlutterFlow Pub Dependencies (not something I added manually) and is read-only from my side. Note: this looks similar to #7068, but different root cause — my Custom Pub Dependencies tab is empty (no custom deps with bad format), and the error is a git authentication failure ('could not read Username'), not a pubspec YAML syntax error.

Expected Behavior

Run/Test Mode should successfully fetch packages and load the app preview.

Steps to Reproduce

1. Open the AnimalAlert project in FlutterFlow / 2. Click 'Run' (or 'Test Mode') to preview the app / 3. Package fetching starts, then fails with 'Error Getting Packages' / 'flutter pub get failed with exit code 69' / 4. Clicking 'Retry' reproduces the same error consistently, both from Run mode and from a completely fresh Test Mode session

Reproducible from Blank

Visual documentation

Environment

- FlutterFlow version: (Flutter SDK shown as 3.38.6 in error message)
- Platform: Web (also reproduced via FlutterFlow Desktop app)
- Browser name and version: Chrome (latest)
- Operating system and version affected: macOS Sequoia 15.7.9 (MacBook Pro 15-inch 2018, Intel)

Additional Information

This is blocking all testing before launch (target: January). The project itself has 0 errors in the Issues panel — confirmed via Activity Monitor that CPU usage stays idle during the failed build, ruling out a local hardware issue.

I'm experiencing the same issue in FlutterFlow Test Mode, but in my case the failing FlutterFlow dependency is webviewx_plus.
flutter pub get failed with exit code 69
fatal: could not read Username for 'https://github.com': No such device or address
FlutterFlow attempts to clone: https://github.com/FlutterFlow/webviewx_plus.git
I confirmed that webviewx_plus is not present in my generated pubspec.yaml, Custom Pub Dependencies, FlutterFlow Pub Dependencies, or global project search. This appears to be the same Git authentication/build infrastructure issue affecting another FlutterFlow-owned dependency.

Hello everyone! I just wanted to let you know that this issue was resolved a few hours ago. I'd like to check in and see if anyone is still experiencing the problem on their end. Please feel free to share your feedback. Thanks!

Hi, quick update: the issue was still occurring for me today (September 4, 2026) with the debug_panel_proto dependency and exit code 69, even after multiple retries and a new Test session.

However, I have just tried again and Test/Run is now working correctly.

So the issue appears to have been intermittent and is currently resolved on my side.

Thank you!
