Hot Reload deletes lib/ folder during Local Run

[CodeInvictus]

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

When using Local Run and pressing Hot Reload in FlutterFlow, the entire lib/ folder is being deleted. This includes main.dart and other critical files, causing the app to crash with the error:

Target file "lib/main.dart" not found.

Expected Behavior

Working!!

Hot Reload should reload code without altering or deleting any Dart files in the lib/ folder.

Steps to Reproduce

I´m using HP laptop (Windows) and my physical device is an Goggle Pixel 7a

1. Create or open a project in FlutterFlow.

2. Set up Local Run (I use Flutter 3.22.1 + Java 17).

3. Run the app on a physical device.

4. Press Hot Reload inside FlutterFlow.

5. Observe that lib/ folder is emptied or deleted.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Bug Report Code (Required)

Performing hot reload... The entrypoint file (i.e. the file with main()) C:\Users\ChristoferEkman\AppData\Roaming\FlutterFlow\flutterflow\workout_app\lib\main.dart cannot be found. Moving or renaming this file will prevent changes to its contents from being discovered during hot reload/restart until flutter is restarted or the file is restored. W/WindowOnBackDispatcher(24059): OnBackInvokedCallback is not enabled for the application. W/WindowOnBackDispatcher(24059): Set 'android:enableOnBackInvokedCallback="true"' in the application manifest. Reloaded 0 libraries in 670ms (compile: 174 ms, reload: 0 ms, reassemble: 126 ms).
