In my case, the issue shows up in only my project. If I create a new project and run works perfectly. However, I couldn't run the project that I intended to run. I've tried this.

  1. If the project is in the Flutter folder, change it to a different folder.
  2. Remove the windows directory to ensure a clean setup: command :- Remove-Item -Recurse -Force .\windows
  3. flutter clean
  4. Regenerate the windows Directory: command :- flutter create .
  5. flutter pub get and run

Do not run flutter build (I was running: flutter pub run msix:create --store) in PS (PowerShell) terminal, run it in the command prompt.

The above worked for me.

I had this error many time now and i tried everything but one thing that solved it for me, was moving the flutter project highter up in the windows file structure, because windows (and apparently cmake) has problems creading or writing binaries too far down.

You can copy the

lib/main.dart

file and just recreate the flutter project by running this command in PowerShell to any directory you like:

flutter create chatapp

In my case only running flutter clean && flutter pub gets the issue resolved..

I finally found the solution flutter is looking for app.so file in project_folder\build\windows\runner\Debug\data\app.so; but the app.so file is actually in project_folder\build\windows\runner
to fix the problem just move app.so file from project_folder\build\windows\runner\ to project_folder\build\windows\runner\Debug\data\ and it will work

  1. Download Visual Studio 17 2022
  2. Delete CMakeLists.txt from project (path: your_prject_name/windows/CMakeLists.txt)
  3. Run in terminal flutter clean
  4. Then run flutter create .

Go flutter/packages/flutter_tools/lib/src/windows and open build_windows.dart file and on line 24 change:

 const int kCurrentUwpTemplateVersion = Visual Studio 17 2022;

Save the file and run flutter. Select the windows device. It will run fine by now without any errors 🎉.

3rd Feb 2022 Update: The latest version of Flutter, version 2.10 stable, has this issue fixed along with stable desktop support for Windows.

Update: The flutter beta channel (2.9.0-0.1.pre onwards) comes with a fix.

According to this issue on the main flutter repo, Flutter prior to version 2.9 does not support Visual Studio 2022. If you want to build while targeting Windows you'll either have to install VS 2019 alongside 2022 or use this workaround:

The current workaround is : download your appropriate flutter version, edit _cmakeVisualStudioGeneratorIdentifier in https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/windows/build_windows.dart#L25-L28 to your appropriate CMake Visual Studio Generator. You can get the currently available CMake Visual Studio Generators on this page : https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html#id13.

By default the _cmakeVisualStudioGeneratorIdentifier comes with CMake Visual Studio 2019 Generator. If you are going to use CMake Visual Studio 2022 Generator - firstly ensure your visual studio 2022 distribution contains Cmake 3.21 or later, refer https://cmake.org/cmake/help/latest/generator/Visual%20Studio%2017%202022.html for details.

To apply these changes on Windows:

  • Edit path\to\flutter\packages\flutter_tools\lib\src\windows\build_windows.dart, and change the constant on line 28 from 'Visual Studio 16 2019' to 'Visual Studio 17 2022'
  • Delete flutter_tools.stamp and flutter_tools.snapshot in path\to\flutter\bin\cache\ (to cause flutter to regenerate its build tools with the new source code you changed above)
  • In the project path, run flutter clean to remove cached CMake files referring to the wrong Visual Studio version
  • In the project path, run flutter run -d windows to restart the build (successfully, this time)
