Unable to find directory entry in pubspec.yaml" when building Flutter app for Windows

Question

I'm trying to build my Flutter app for Windows, but I keep running into the following error:

CUSTOMBUILD : error : unable to find directory entry in pubspec.yaml: D:\\solidcheck\\online\\assets\\images\\ [D:\\solidcheck\\online\\build\\windows\\x64\\flutter\\flutter_assemble.vcxproj]

C:\\Program Files\\Microsoft Visual Studio\\2022\\Community\\MSBuild\\Microsoft\\VC\\v170\\Microsoft.CppCommon.targets(254,5): error MSB8066: Custom build for 'D:\\solidcheck\\online\\build\\windows\\x64\\CMakeFiles\\2b5807d9d0daadf5bd2fe86d3a97c0f1\\flutter_windows.dll.rule;D:\\solidcheck\\online\\build\\windows\\x64\\CMakeFiles\\3da8e4db21fc5d1c48fd0b85b7c50cbd\\flutter_assemble.rule' exited with code -1. [D:\\solidcheck\\online\\build\\windows\\x64\\flutter\\flutter_assemble.vcxproj]

Error: Build process failed.

It seems to be related to a missing directory entry in pubspec.yaml for assets. I have verified that the path D:\\solidcheck\\online\\assets\\images\\ exists and contains the expected files.

What I've Checked:

1. Verified Asset Path: I confirmed that the path D:\\solidcheck\\online\\assets\\images\\ exists and is correctly listed under the assets section in pubspec.yaml.

2. Clean Build: I ran flutter clean and then tried to rebuild the project.

3. Dependencies: I checked that all dependencies and Flutter plugins are up-to-date and correctly configured.

4. Reinstalled Tools: I reinstalled the necessary build tools and verified that Visual Studio and CMake are properly set up.

pubspec.yaml File:

        - asset: fonts/TrajanPro_Bold.ttf

What I Expected:

I expected the build process to complete successfully without errors, specifically resolving the issue where the build system is unable to find the directory entry specified in pubspec.yaml.

Any Suggestions?

How can I resolve this issue? Any help or suggestions would be greatly appreciated!
