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();
