A “Transition” represents a change of one state to another state. In contrast, slide transitions mean changing one slide smoothly to another. Using Flutter, a software development kit (SDK), users can make a variety of slide transitions. This SDK is built on Dart programming language. The purpose of Flutter is to build user interfaces with powerful animations and graphics.

The Flutter slide transition widget can animate widget positions from their original one. In the Flutter app, animation enhances user's interest and entertains them. Moreover, it boosts brand identity and remains memorable to the users. In this article, we will discuss Flutter slide transitions along with how to implement slide transitions in the Flutter app.

Part 1. Understanding Slide Transition in Flutter

SlideTransition Flutter represents a widget with the ability to animate the position of the child widget that is under focus. To present this dynamic shift, two different inputs are undertaken, which include the child widget and the animation. It animates the widget's position relative to its normal position and slides through with the help of tween.

This animated child-widget transition is based on the animation and manipulates the position with the help of the offset value. This value defines the starting and ending points of the child widget and is referred to as the AnimationController component in Flutter. The entire widget is wrapped up with SlideTransition.

Additionally, SlideTransition can move diagonally, wither from bottom to top, or any custom position. Also, this goes off-screen and in-screen by creating entering or exiting effects. Seeing all the components, one can experiment with animation and change their duration and curves. 

Part 2. Key Components of Slide Transition

To create attractive Flutter animations, it is essential to understand the core concepts first. Below are some foundations of the slide transition Flutter framework:

1. Animation Controller

The AnimationController component of the framework manages the duration and progress of the entire animation. The complete progress of the animation is managed through this component, which also defines the duration and playback methods. While staying within this component, the user can control its playback through the reverse, forward, and stop methods.

2. Animation

Animation in the Flutter SlideTransition framework represents a complete component executed through variating values. While the primary motive of the animation is to display the smoothness in the movement of the object, "Animation" in SlideTransition holds the animation and the AnimationController. This clarifies that the object to be animated and its speed is controlled throughout.

For instance, incorporating the animation of growing an image slowly within the transition will be directed through this component. Essentially, it will be used to identify the starting and ending points for this animation.

3. Tween

Tween is the attribute that defines the position of the child widget and potentially provides the pathway of the animation. It defines the offset value, which controls and mirrors the position of the animation with the child widget. Along with controlling the size of the animation, it can also support other widget properties, including color, opacity, and position. It shows how the faded animations are smoothly created.

4. Curved Animation

To generate a complex animated effect, Flutter offers a comprehensive system of settings to apply across the animations. Referred to as Carousels, it features the ability to slide animations in both directions, giving flexibility in creation. Curved animation in the Flutter slide transition makes it naturally appealing.

Part 3. Step-by-Step Guide: Implementing Slide Transition in the Flutter App

When it comes to implementing the animation, the concern lies in the successful execution of the process. Thus, let us guide you step-by-step on how to implement the Flutter SlideTransition:

Step 1: Import Required Packages

First, open your VS code and create a Flutter application there. Install the module by opening the command palette by pressing “Ctrl + Shift + P” on your keyboard. Now, select "Flutter: New Project" from the displayed drop-down list. Next, select the "Application" and choose a project location. Name the file and head to create a widget by writing Dart code.

To add slide transitions and implement a design, you need to import respective Dart code packages. While these ensure the proper operation of any code within the platform, be careful while importing libraries. Use the code “import 'package:flutter/material.dart” for that purpose. In addition, one can even use materialApp and stateless widgets, which will help in later establishments.

Step 2: Set Up the Animation Controller

The animation controller places the animation in a set value and uses it to reverse, stop, and forward it. It works as a controller of the animation behaviors. For example, one can repeat the animation by prompting the controller.repeat. Any animation applied in the slide transition will be mainly controlled through this system:

You have to define the desired animation and animation controller. In this regard, the following code snippet explains how the Animation Controller can be created on demand to manage the duration of the animation:

late final AnimationController _controller = AnimationController(

    duration: const Duration(seconds: 2),

    vsync: this,

  )..repeat(reverse: true);

Here, the last parameter, "repeat(reverse: true);" keeps the animation repeating and sets up a reverse trend.

Step 3: Create Animation and Tween

Animation refers to the animating speed of an object from the starting point (0) to its actual size (1). In this way, animated objects slowly and smoothly grow from smaller to bigger. Tween works the same, but it used to change color and opacity, too.

To create color or any other adjustment with tween, there is a different starting point and a separate ending point. You can also define the parameters for curved animation with starting and ending points, defining the importance of tween in slide transition making.

late final Animation _offsetAnimation = Tween(

    begin: Offset.zero,

    end: const Offset(1.5, 0.0),


    parent: _controller,

    curve: Curves.elasticIn,


Step 4: Apply Curved Animation

For complex animations, it is crucial to have a system that can apply both linear and curved animations. CurvedAnimation in Flutter provides the ability to improve the overall look and make an impressive outlook of the animation.

The following example is a snippet of how a simple addition of CurvedAnimation can be used in such conditions:

colorAnimation = ColorTween(begin: Colors.blue, end: Colors.yellow)

      .animate(CurvedAnimation(parent: controller, curve: Curves.bounceOut));

Step 5: Build UI with Slide Transition

To build a user interface with slide transitions, define UI first. From the main function, every Flutter code has some starting points. There is a runApp method provided as a 'flutter/material.dart’ package, and the code is:

void main() {



Now, with the material.dart package, you can create a stateless widget. Overrule the build method that is used in the stateless widget. Afterward, using all the parameters, return to the materialApp widget and use the code:

class MyApp extends StatelessWidget {

  const MyApp({super.key});

  // This widget is the root of your application.


  Widget build(BuildContext context) {

    return const MaterialApp(

      title: 'Slide Transition Widget,'

      home: SlideTransitionWidget(),




return Scaffold(

Step 6: Triggering the Animation

To release the resources and dispose of the controllers, use the code for triggering the entire slide transition animation in Flutter:


      appBar: AppBar(

          title: const Text('SlideTransition Sample'),

          backgroundColor: Colors.green),

      body: Center(

          child: SlideTransition(

        position: _offsetAnimation,

        child: Padding(

          padding: const EdgeInsets.all(8.0),

          child: Image.network(





Set the color AppBar in the center and define the slide transition Widget in the center. Now, run the code by using the Android emulator. Furthermore, you can run the code by connecting your physical device.
