Hi friends,

In this quick example, let's see Flutter Animation Example Tutorial. you will learn flutter transform animation example. we will help you to give example of how to implement animation in flutter app. step by step explain how to build animation in flutter.

I will give you simple Example of how to add animation in flutter

So let's see bellow example:

Step 1: Create Flutter Project

Follow along with the setup, you will be creating an Flutter app.

$flutter create flutter_animation_tutorial   

Navigate to the project directory:

$cd flutter_animation_tutorial   

Step 2: Main File

Create a main.dart file in the lib directory

import 'package:flutter/material.dart';
void main() => runApp(const LogoApp());
class LogoApp extends StatefulWidget {
    const LogoApp({Key? key}) : super(key: key);
    @override
    _LogoAppState createState() => _LogoAppState();
}
class _LogoAppState extends State with SingleTickerProviderStateMixin {
    late Animation animation;
    late AnimationController controller;
    late AnimationController animationController;
    @override
    void initState() {
        super.initState();
        controller =
            animationController = AnimationController(duration: const Duration(seconds: 2), vsync: this);
        // #docregion addListener
        animation = Tween(begin: 0, end: 300).animate(controller)
        ..addListener(() {
            // #enddocregion addListener
            setState(() {
                print (animation.value.toString());
            });
            animation.addStatusListener((status){
                if(status == AnimationStatus.completed){
                    animationController.reverse();
                } else if(status == AnimationStatus.dismissed) {
                    animationController.forward();
                }
            });
        });
        controller.forward();
    }
    @override
    Widget build(BuildContext context) {
        return Center(
            child: Container(
                margin: const EdgeInsets.symmetric(vertical: 10),
                height: animation.value,
                width: animation.value,
                child: const FlutterLogo(),
            ),
        );
    }
    @override
    void dispose() {
        controller.dispose();
        super.dispose();
    }
}

Run this Debug App
