Getting Started

Install dependencies

dependencies:
  show_up_animation: ^1.0.2

Then import wherever you want to implement the animation

import 'package:show_up_animation/show_up_animation.dart';

ShowUpAnimation

Wrap any widget you want to animate inside ShowUpAnimation widget and provide a Duration() to delayStart field to control after how much delay the animation fires.

ShowUpAnimation(
  delayStart: Duration(seconds: 1),
  animationDuration: Duration(seconds: 1),
  curve: Curves.bounceIn,
  direction: Direction.vertical,
  offset: 0.5,
  child: YourWidget(),
),

ShowUpList

To create a list of "show up" animations, use ShowUpList and provide your list of widgets to children parameter.

ShowUpList(
  direction: Direction.horizontal,
  animationDuration: Duration(milliseconds: 1500),
  delayBetween: Duration(milliseconds: 800),
  offset: -0.2,
  children: <Widget>[
    Widget1(),
    Widget2(),
    Widget3(),
    Widget4(),
  ],
),
