Hi Folks, In this article, we will learn about adding the animations while transiting from one page to other in Flutter. We would be covering different types of animation and implementing basic animation in flutter using the package page_animation_transition.

Introduction

Animations play a vital role in enhancing the user experience of your app. But what exactly are animations?

A design language, such as Material, defines standard behaviors when transitioning between routes (or screens). Sometimes, though, a custom transition between screens can make an app more unique.

In this tutorial, we will use the package page_animation_transition which simplifies adding transitions on the page.

Exploring different transitions using the plugin

Step 1: Add page_animation_transition in pubspec.yaml

Step 2: Import the library on PageOne, assuming that you are transiting from PageOne to PageTwo

Following are the types of animations that are supported by the library:

BottomToTopTransition
TopToBottomTransition
RightToLeftTransition
LeftToRightTransition
FadeAnimationTransition
ScaleAnimationTransition
RotationAnimationTransition
TopToBottomFadedTransition
BottomToTopFadedTransition
RightToLeftFadedTransition
LeftToRightFadedTransition

Step 3: Add the following lines of code for navigation

Navigator.of(context).push(PageAnimationTransition(page: const PageTwo(), pageAnimationType: BottomToTopTransition()));

For predefined routes:

onGenerateRoute: (settings) {
switch (settings.name) {
case '/pageTwo':
return PageAnimationTransition(child: PageTwo(), pageAnimationType: LeftToRightFadedTransition());
break;
default:
return null;
}
}

Navigator.pushNamed(context, '/pageTwo');

Output:

child: const Text('Top to bottom')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: RightToLeftTransition()));
},
child: const Text('Right To Left')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: LeftToRightTransition()));
},
child: const Text('Left to Right')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: FadeAnimationTransition()));
},
child: const Text('Faded')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: ScaleAnimationTransition()));
},
child: const Text('Scale')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: RotationAnimationTransition()));
},
child: const Text('Rotate')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: TopToBottomFadedTransition()));
},
child: const Text('Top to Bottom Faded')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: BottomToTopFadedTransition()));
},
child: const Text('Bottom to Top Faded')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: RightToLeftFadedTransition()));
},
child: const Text('Right to Left Faded')),
ElevatedButton(
onPressed: () {
Navigator.of(context).push(PageAnimationTransition(
page: const PageTwo(),
pageAnimationType: LeftToRightFadedTransition()));
},
child: const Text('Left to Right Faded')),
],
),
),
);
}
}

Output:
