error MSB3073 when building Flutter desktop

Question

Recently I just got the issue below when I tried to build a release version of a Flutter Windows Desktop application. I can run and build the project normally in debug mode. However, when it came to release mode, it failed. I am not an expert in windows apps, so I have no clue what's going on. Any suggestion?

Answer 1

Max Ked's solution worked once for me and failed next! I tried this and it works:

• Delete .dart_tool folder.
• run flutter pub get --no-example. Flutter extension should suggest you run this command by the extension itself after you delete the mentioned folder.

Answer 2

Open CMD with administration rights, then navigate to your project folder and paste flutter build windows. It's helped me once.

Short CMD example :

1. cd myflutterproject

2. flutter build windows

Another possible solution is open project in Visual Studio:

YOUR_FLUTTER_PROJECT_FOLDER\build\windows\x64\PROJECT_NAME.sln and try build project
