如何在启动动画期间更改 iOS 应用程序图标背景颜色？

Question

When launching a flutter built iOS application, I briefly get this black background surrounding the launch screen. How would you change the black background depicted in the image? I tried changing the launch screen background color in Xcode, but I still get this black "border".

Answer 1

The black "border" in the opening app animation has to do with the way the default flutter icons were generated. I generated my own icons using this generator , and the app animates as intended.
