Description

Describe the bug The application icon in the top-left corner of notifications displays inconsistently on Windows 10 and Windows 11. The icon sometimes appears correctly and sometimes does not appear at all, with no clear reproduction pattern. The icon file is an ICO file from the assets package.

To Reproduce Configure the notification plugin in a Flutter application using an ICO file from assets as the app icon Run the application on Windows 10 or Windows 11 Trigger a notification to display Observe the app icon in the top-left corner of the notification The icon may sometimes display correctly, and sometimes not appear at all, with inconsistent behavior

Expected behavior The application icon should consistently and correctly appear in the top-left corner of every notification.

Sample code to reproduce the problem

    var iconPath = File.fromUri(WindowsImage.getAssetUri("assets/images/logo/logo.png")).absolute.path;
    final windowsSettings = WindowsInitializationSettings(
      appName: Constants.appName,
      appUserModelId: Constants.pkgName,
      guid: Constants.appGuid,
      iconPath: iconPath,
    );

This issue can occur during both the development phase and in released versions. In most cases, the icon does not appear. The released version was installed using an InnoSetup packaged EXE installer.

Research direction
Investigate the icon path handling in the flutter local notifications plugin for Windows. Check the WindowsInitializationSettings class and how iconPath is used to load the ICO file. Look at the plugin's Windows notification implementation to see if there is a caching or loading issue. Review comments in the issue for any suggested fixes or reproduction details. Consider comparing with the plugin's icon handling on other platforms.
