Why can't Get.theme trigger view update, when the app brightness mode?

[ShookLyngs]

When using Get.theme.xxx as value, it has different behaviour to the Theme.of(context).xxx.

When I use Theme.of as value, then I trigger Get.changeTheme() manually, the page updated normally.
But when I use Get.theme as value, the page cannot update normally, when the app brightness mode changed.

Is this normal?

Yes, this is the expected behavior, if you expect changes you should use Get context extensions, like context.theme.
Get.theme, Get.height, Get.widget, can only be used within functions, within widgets you must use context.theme, context.width, context.height, etc.
