@0Vipin0 did you clone the repository? (as opposed to using pub.dev distribution)

[alexmercerind]

If yes, you need to fetch respective submodules aswell.

git submodule update --init --recursive

Learn more: https://stackoverflow.com/a/8084186/12825435

[0Vipin0]

Tried that also but issue is still coming.

Steps taken:
git submodule update --init --recursive

git pull --recurse-submodules --jobs=10

flutter clean

flutter run -d windows

You can clone again with --recursive

[alexmercerind]

Let know if it doesn't work. Not issue with library regardless. It could be issue that your git CLI isn't updated & symlinks aren't getting generated correctly on Windows.

[0Vipin0]

After cloning from again with recursive flag, it still doesn't work.

git clone --recursive https://github.com/harmonoid/libwinmedia.git

flutter clean

Same error before is coming

[alexmercerind]

@0Vipin0 could you send screenshot of the flutter folder ? (inside the folder that you cloned)

[0Vipin0]

Here is my folder structure of the flutter folder inside the cloned repo.

[alexmercerind]

@0Vipin0

As you can see .master file is not generated as a symlink (see repo for comparison). I think your git is not updated (please update).
If your git was updated that symlink would've been resolved as a proper Windows shortcut.

[0Vipin0]

@alexmercerind I have updated the git to the latest version for windows, cloned the repo again and ran the example again but the issue still persist.

[bdlukaa]

@alexmercerind can't we do the same thing we do on system_theme. Fetch it from github?

[alexmercerind]

@0Vipin0,
See how my git has generated automatic shortcut based on Linux type symlink (unlike yours).

@bdlukaa

back then, I didn't know much about submodules. Using file() DOWNLOAD from CMake, it can cause problems for developers in country where GitHub available. Extracting contents of archive adds another process to the game. Didn't wanna go with it.

[alexmercerind]

@0Vipin0 I recently published a version on pub.dev. You may use it in your app. Hope you'll find it working.

But it can run on 16.11.3
