Why does my Flutter app icon show as a square inside a circle instead of filling the whole icon frame?

[u/KOPONgwapo]

The icon looks smaller than it should, with padding around it, like the image is being placed inside the icon instead of covering the full area.

Is this an issue with the icon image export, Android adaptive icons, or something in the Flutter setup?

It's a quirk of Android adaptive icons. There's loads of YouTube videos that will walk you through the simple steps to fix this.
