Flutter Fader 是一个轻量级的动画小部件，可平滑地淡入淡出子小部件。当淡出时，子小部件将从组件树中移除，确保无法与之交互。非常适合用于创建干净、响应式的用户界面过渡效果，例如加载指示器、模态框或动态内容更新。该包支持所有主要平台，包括 Android、iOS、Web、macOS、Windows 和 Linux，使其在跨平台应用中具有高度灵活性。它可无缝集成到 Flutter 的动画系统中，且设置简单。

A widget for Flutter that allows you to fade in and out a child widget.
When a widget is faded out it is no longer in the view tree. Meaning that it can't be used or interacted with. Handy for hiding buttons.
In your Flutter project, add the package to your dependencies
dependencies:
...
flutter_fader: ^2.0.0
Examples of how to use the widget, and that can also be ran on your device, can be found in the example directory
Import the fader package
import 'package:flutter_fader/flutter_fader.dart';
Create a fader controller, this allows you to control when the Fader fades in or out
FaderController faderController = new FaderController();
Create a fader widget, and pass it the fader controller
Fader(
controller: faderController,
duration: const Duration(milliseconds: 50),
child: Text("Hello, world!"),
)
Now you can fade the child widget in and out at will
faderController.fadeOut();
faderController.fadeIn();
