Flutter - AnimatedPhysicalModel Widget

In Flutter, the AnimatedPhysicalModel widget is used to create animations that transition between different physical properties of a widget, such as elevation, shape, and colour. In this article, we are going to implement the AnimatedPhysicalModel widget. A sample video is given below to get an idea about what we are going to do in this article.

Basic Syntax of AnimatedPhysicalModel

AnimatedPhysicalModel(
 duration: Duration(milliseconds: 500), // Animation duration
 curve: Curves.easeInOut, // Animation curve
 elevation: _elevation, // Elevation (animate this property)
 shape: BoxShape.rectangle, // Shape of the widget (rectangle or circle)
 shadowColor: Colors.grey, // Color of the shadow
 color: Colors.blue, // Background color of the widget
 borderRadius: BorderRadius.circular(8.0), // Border radius
 child: YourChildWidget(), // The widget you want to animate
)

Required Tools

To build this app, you need the following items installed on your machine:

• Visual Studio Code / Android Studio
• Android Emulator / iOS Simulator / Physical Device device.
• Flutter Installed
• Flutter plugin for VS Code / Android Studio.

Step By Step Implementation

Step 1: Create a New Project in Android Studio

To set up Flutter Development on Android Studio please refer to Android Studio Setup for Flutter Development, and then create a new project in Android Studio please refer to Creating a Simple Application in Flutter.

Step 2: Import the Package

First of all import material.dart file.

import 'package:flutter/material.dart';

Step 3: Execute the main Method

Here the execution of our app starts.

Step 4: Create MyApp Class

In this class we are going to implement the MaterialApp , here we are also set the Theme of our App.

Step 5: Create AnimatedPhysicalModelDemo Class

In this class we are going to Implement the AnimatedPhysicalModel widget that help to creating an animated card like container that changes its elevation, shape, and color when the "Add Elevation" or "Remove Elevation" button is pressed. Comments are added for better understanding.

 AnimatedPhysicalModel(
 duration: Duration(seconds: 1), // Animation duration
 curve: Curves.easeInOut, // Animation curve
 elevation: _isElevated ? 68.0 : 0.0, // Animate elevation
 shape: BoxShape.rectangle, // Shape of the container
 shadowColor: Colors.green, // Color of the shadow
 color: Colors.green, // Color of the container
 borderRadius: BorderRadius.circular(8.0), // Border radius
 child: Container(
 width: 200,
 height: 200,
 child: Center(
 child: Text(
 'Animated',
 style: TextStyle(
 color: Colors.white,
 fontSize: 24,
 ),
 ),
 ),
 ),
 ),
