推荐答案

是的，可以.实际上，main()函数可以标记为async，因此您可以在main()方法主体中运行runApp(...)之前做任何需要做的事情，甚至是异步进行的 .这样，在调用runApp(...)之前，将显示启动屏幕，直到检索到异步结果为止.例如:

Yes, yes you can. The main() function can actually be tagged as async, so you can do whatever you need to do before running runApp(...) in the main() method body, even asynchronously. This way, the splash screen will be shown until your asynchronous result is retrieved, before calling runApp(...). For example:

Future<void> main() async {

// Do whatever you need to do here
final home = await setHomeWidgetDependingOnLoginStatus();

return runApp(MyApp(home: home));
}
