Installation

Add to your pubspec.yaml:

dependencies:
  philiprehberger_animation_kit: ^0.1.0

Then run:

flutter pub get

Usage

import 'package:philiprehberger_animation_kit/animation_kit.dart';

FadeIn(
  duration: Duration(milliseconds: 500),
  child: Text('Hello, World!'),
)

Slide In

SlideIn.fromRight(child: Text('From right'))
SlideIn.fromBottom(
  duration: Duration(milliseconds: 500),
  child: Text('From bottom'),
)

Scale In

ScaleIn(
  curve: Curves.easeOutBack,
  child: Icon(Icons.star, size: 48),
)

Bounce

Bounce(
  duration: Duration(milliseconds: 800),
  child: Text('Boing!'),
)

Shake

Shake(
  magnitude: 12.0,
  oscillations: 4,
  child: Text('Error!', style: TextStyle(color: Colors.red)),
)

Pulse

Pulse(
  minScale: 0.9,
  maxScale: 1.1,
  child: Icon(Icons.favorite, color: Colors.red, size: 48),
)

Animation Sequence

AnimationSequence(
  staggerDelay: Duration(milliseconds: 150),
  children: [
    Text('First'),
    Text('Second'),
    Text('Third'),
  ],
)

Spring Physics

SpringWidget(
  target: Offset(100.0, 50.0),
  stiffness: 300.0,
  damping: 15.0,
  child: Container(
    width: 60,
    height: 60,
    decoration: BoxDecoration(
      color: Colors.green,
      shape: BoxShape.circle,
    ),
  ),
)

API

Widget	Description
FadeIn	Fade in a child widget with configurable duration, curve, and delay
SlideIn	Slide in from a direction (left, right, top, bottom)
ScaleIn	Scale from 0 to 1 with configurable curve
Bounce	Scale with elastic overshoot (Curves.elasticOut)
Shake	Horizontal shake using sine-based offset with decay
Pulse	Repeating scale animation (grows and shrinks)
AnimationSequence	Staggered reveal of child widgets in sequence
SpringWidget	Spring physics positioning with configurable stiffness and damping
