flutter_staggered_animations_plus

Easily add staggered animations to your ListView, GridView, Column and Row children as shown in Material Design guidelines.

A modernized fork of flutter_staggered_animations with Dart 3+ and Flutter 3.x support. Designed for the latest Flutter and Dart SDKs (Flutter ≥3.10.0, Dart ≥3.0.0).

ListView	GridView	Column

Getting Started

Installation

Add this to your pubspec.yaml:

dependencies:
  flutter_staggered_animations_plus: ^1.0.0

Then run:

flutter pub get

Import

import 'package:flutter_staggered_animations_plus/flutter_staggered_animations_plus.dart';

Usage

ListView

AnimationLimiter(
  child: ListView.builder(
    itemCount: 100,
    itemBuilder: (BuildContext context, int index) {
      return AnimationConfiguration.staggeredList(
        position: index,
        duration: const Duration(milliseconds: 375),
        child: SlideAnimation(
          verticalOffset: 50.0,
          child: FadeInAnimation(
            child: YourListChild(),
          ),
        ),
      );
    },
  ),
);

GridView

AnimationLimiter(
  child: GridView.count(
    crossAxisCount: 2,
    children: List.generate(100, (int index) {
      return AnimationConfiguration.staggeredGrid(
        position: index,
        duration: const Duration(milliseconds: 375),
        columnCount: 2,
        child: ScaleAnimation(
          child: FadeInAnimation(
            child: YourGridChild(),
          ),
        ),
      );
    }),
  ),
);

Column / Row

Column(
  children: AnimationConfiguration.toStaggeredList(
    duration: const Duration(milliseconds: 375),
    childAnimationBuilder: (widget) => SlideAnimation(
      horizontalOffset: 50.0,
      child: FadeInAnimation(
        child: widget,
      ),
    ),
    children: yourChildren,
  ),
);

Available Animations

Animation	Description
FadeInAnimation	Fades a child in (opacity 0 → 1)
SlideAnimation	Slides a child from a given offset to its final position
ScaleAnimation	Scales a child from a given scale to 1.0
FlipAnimation	Flips a child along the X or Y axis

Combining Animations

You can nest multiple animations to create compound effects:

SlideAnimation(
  verticalOffset: 50.0,
  child: FadeInAnimation(
    child: ScaleAnimation(
      child: YourWidget(),
    ),
  ),
)

Animations must be direct children of AnimationConfiguration.

AnimationConfiguration

AnimationConfiguration is an InheritedWidget that shares its animation settings with its children (mainly duration and delay).

Named constructors

Depending on the scenario in which you will present your animations, you should use one of AnimationConfiguration's named constructors.

• AnimationConfiguration.synchronized if you want to launch all children's animations at the same time.
• AnimationConfiguration.staggeredList if you want to delay the animation of each child to produce a single-axis staggered animations (from top to bottom or from left to right).
• AnimationConfiguration.staggeredGrid if you want to delay the animation of each child to produce a dual-axis staggered animations (from left to right and top to bottom).

If you're not in the context of a ListView or GridView, an utility static method is available to help you apply staggered animations to the children of a Row or Column:

• AnimationConfiguration.toStaggeredList

You can override duration and delay in each child Animation if needed.

AnimationLimiter

Wrap your scrollable list with AnimationLimiter to prevent animations from running on items that have already appeared after the initial frame build. This ensures animations only play on items visible during the first render.
