In the top bar of the Android screen, where the app icons are usually displayed, I see either a square or a Flutter icon.
On iPhones, all icons are displayed perfectly.
Of course I downloaded the adaptive icon for Android according to the documentation, but it doesn't help.
When I downloaded the application code, I found the Flutter icon in the folder where icons for Android are stored. Why is it not automatically replaced by the app icon?
Interesting thing is that sometimes in the notification bar the icons don't load either and instead of them an empty square or Flutter icon is displayed, although a minute earlier there was an app icon.
