On LightTheme environment the flag is not displaying

[RizanPSTU]

My main widget has two theme (light and dark). In a dark-themed environment, everything works fine. But on the light theme, it is not displaying the texts or the flag. I can change the text color using the style property. But the flag is not able to change and is not displaying properly. How do I solve this issue?
