有两种方式:
不需要
上下文
.可以在initState
中使用,例如:
var brightness = SchedulerBinding.instance!.window.platformBrightness;
bool isDarkMode = brightness == Brightness.dark;
context
是必需的:
context
is required:
var brightness = MediaQuery.of(context).platformBrightness;
bool isDarkMode = brightness == Brightness.dark;
