颤动闪屏 [英] Flutter Splash Screen

问题描述

如何在闪屏中显示闪屏？因此，有一个启动图标选项。我在各自的文件夹中添加了适用于ios和android的图像。我的问题是速度太快。因此，它直接打开MyApp（）。我希望我的应用程序不显示任何内容，并让Splash进行控制，直到我弄清楚该将用户带到哪个屏幕为止（在MyApp中，我想进行初始化）

How do I show a splash Screen in flutter? So there is an option for launch icon. I added images for ios and android in their respective folders. My problem is it is too fast. So it directly opens MyApp(). I want my app to not show anything and let splash take control until I figure out which screen to take the user to (In MyApp I want to do intialization)

推荐答案

您可以在 initState 中使用 Future.delayed 构造函数。

You can use Future.delayed constructor in your initState. This will keep your SplashScreen for the duration you specify before the navigation happen.

class SplashScreen extends StatefulWidget {
  @override
  _SplashScreenState createState() => new _SplashScreenState();
}

class _SplashScreenState extends State<SplashScreen> {
  @override
  void initState (){
    super.initState();
    // TODO initial state stuff
    new Future.delayed(const Duration(seconds: 4));
  }
  @override
  Widget build(BuildContext context) {
    //build
  }
}
