How To Create Liquid Swipe Animation In Flutter

Today tutorial, I am going to show you how to create Liquid Swipe Animation in Flutter. liquid Swipe animation is amazing and its Created for iOS Platform and for React Native Platform. this animation Or Liquid Swipe Animation is Inspired by Cuberto.

For this animation, we are will Need liquid_swipe Package. Liquid Swipe is the Unveils a New Page like Liquid Animation Just like the Above animation.

📱 What we’re going to Build

How to Create Liquid Swipe Animation in Flutter

Let’s Start the Tutorial

If you Don’t know how to Create a Flutter app, check out Getting started with Flutter official tutorial.

First, you will need to add package name liquid_swipe into Pubspec.yaml

In the dependencies: section of your pubspec.yaml, add the following lines as :

liquid_swipe: ^1.3.1

Now run Flutter package get in your terminal which we’ll install liquid_swipe package.

liquid_swipe.dart for LiquidSwipe() method and Helpers.dart for WaveType animation so you can either select circularReveal Or liquidRevel Animation.

Before We Start Coding, You Need to Download Assets For this App.

For that Create a Separate Folder and give a name ‘ assets’ to it & add Assets you can Download Assets File From Here

and Add this Below line into Pubspec.yaml file

assets:
  - assets/img/

fonts:
  - family: Product Sans
    fonts:
      - asset: assets/font/Product_Sans_Bold.ttf
      - asset: assets/font/Product_Sans_Regular.ttf

We need to Create a Simple main.dart file to contain our MyApp widget just like Below Snippet

import 'package:flutter/material.dart';
import 'package:liquid_swipe/Constants/Helpers.dart';
import 'package:liquid_swipe/liquid_swipe.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: LiquidSwipe(),
      ),
    );
  }
}

Okay, In the LiquidSwipe() method we need to Add pages, enbaleloop, fullTransitionValue, enableSlideIcon, waveType, positionSlideIcon.

LiquidSwipe(
          pages: pages,
          enableLoop: true,
          fullTransitionValue: 300,
          enableSlideIcon: true,
          waveType: WaveType.liquidReveal,
          positionSlideIcon: 0.5,
        ),

After that Create three Container for 3 Pages where we will Create Container widget For Each Separate pages.

Before we Start Creating Pages we Need to create For Text Widget Just Like Below Code Snippet in a MyApp widget.

static const TextStyle goldcoinGreyStyle = TextStyle(
     color: Colors.grey,
     fontSize: 20.0,
     fontWeight: FontWeight.bold,
     fontFamily: "Product Sans");

 static const TextStyle goldCoinWhiteStyle = TextStyle(
     color: Colors.white,
     fontSize: 20.0,
     fontWeight: FontWeight.bold,
     fontFamily: "Product Sans");

 static const TextStyle greyStyle =
     TextStyle(fontSize: 40.0, color: Colors.grey, fontFamily: "Product Sans");
       static const TextStyle whiteStyle =
     TextStyle(fontSize: 40.0, color: Colors.white, fontFamily: "Product Sans");

 static const TextStyle boldStyle = TextStyle(
   fontSize: 50.0,
   color: Colors.black,
   fontFamily: "Product Sans",
   fontWeight: FontWeight.bold,
 );

 static const TextStyle descriptionGreyStyle = TextStyle(
   color: Colors.grey,
   fontSize: 20.0,
   fontFamily: "Product Sans",
 );

 static const TextStyle descriptionWhiteStyle = TextStyle(
   color: Colors.white,
   fontSize: 20.0,
   fontFamily: "Product Sans",
 );

So this will be a Six TextStyle is Required for the creating a Pages text style.

final pages = [
  Container(),
  Container(),
  Container(),
];
