[FEATURE REQUEST] multiple windows icons

[matthias-steinkamp]

💬 Description

To get the best resolution on multiple windows explorer views (large icons, list, ...), is it possible to generate a windows .ico with multiple resolutions of the input icon file?
Also the highest resolution of 256px would be nice.

See https://stackoverflow.com/questions/3236115/which-icon-sizes-should-my-windows-applications-icon-include

❓ Platform

Windows

Hi, @matthias-steinkamp as I see flutter windows do not support multiple resolutions icons. Currently, we generate one ico file with 128px and a default ico file only 48px.

Hi @mrrhak, thanks for the quick answer. I'm not a windows dev guru, but I think the rc-file specifies the .ico file and .ico files can hold several icon images for different sizes. Afterwards, windows automatically displays the right image for the desired view in file explorer etc. So I guess, it's not a flutter topic but just how many images are stored in the single .ico file.

"ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately." https://en.wikipedia.org/wiki/ICO_(file_format)

Ohh thanks for clearly explaining. After I'm checking on this image package I think I can try to create a single .ico file from multiple sizes as you want.

Hi @matthias-steinkamp I have added multiple sizes inside a single .ico file in the new version v1.2.1. You can check a generated .ico file here to see multiple sizes have been embedded. Thanks

the generated icon shows one 256px only

I have fixed in v1.2.1
