CachedNetworkImage logs errors / crashes on Windows when image URL returns 404

[duc0103]

Using CachedNetworkImage on Windows, if the image URL is invalid (returns 404 from the server), the app repeatedly logs:

[ERROR:flutter/shell/platform/windows/task_runner_window.cc(61)] Failed to post message to main thread

and sometimes the app crashes.

This happens even when using errorWidget or a custom CacheManager.

Steps to Reproduce:

Use CachedNetworkImage with an invalid URL, for example:

CachedNetworkImage(
imageUrl: "https://brickfever.nl/wp-content/uploads/2022/11/LOGO-2022-Owen-EXPORT.png",
errorWidget: (context, url, error) => Icon(Icons.error),
)

Run the app on Windows.

Observe repeated error logs and/or crash.

Expected behavior:

Image should fallback to errorWidget.

No repeated log spam or crash.

Cache should not store invalid 404 images.

Environment:

Flutter version: 3.35.3

flutter_cache_manager ^3.4.0

cached_network_image version: cached_network_image: ^3.4.1

Platform: Windows 10/11

Additional context:

Issue only occurs on Windows; Android/iOS works fine.

The URL being invalid (404) triggers the log/crash immediately.
