What kind of image do you use for the icon and does it exist in assets folder?

What kind of image do you use for the icon and does it exist in assets folder?

I compiled it several times changing parameters and dependencies because of the other problems it causes me, but I used the one that comes by default in the counter demo. I also tested it using an icon.ico placing it in the assent folder and in the main root but it still remains black. It is like this for the physical and virtual device.

Solved.

Configure color for adaptive background on Android.

In pyproject.toml:

[tool.flet.android]
adaptive_icon_background = "#ffffff" # your color

or use --android-adaptive-icon-background CLI option.
