2. How to Create Animation Using the AnimatedAlign
Widget?
The Flutter Agency focused on the most often used widgets while
creating a Flutter app. If you have a basic understanding of those
widgets, it becomes much easier for anyone to start creating
wonderful apps with Flutter.
Now that Flutter offers animations, you can build wonderful fun-filled
animations in your app by using animated widgets. So, in this article,
we will see the AnimatedAlign widget.
3. To improve your application usability and performance, make sure you
utilize this feature whenever you hire Flutter developer to build your
business application. Sometimes you may need to change the
alignment of a widget, and adding an animation can make the
transition smoother during the transition to the new alignment. In
Flutter, creating such animation can be done thanks easily to the
AnimatedAlign widget.
The Animated Align Widget aligns the child’s location in a given period
in a given alignment automatically. You can also choose an animation
period with a curve. The alignment to the new target will be animated
by the widget.
4. Let’s go over the constructor…
const AnimatedAlign(
{Key? key,
required AlignmentGeometry alignment,
Widget? child,
double? heightFactor,
double? widthFactor,
Curve curve = Curves.linear,
required Duration duration,
VoidCallback? onEnd}
)
There isn’t much in the constructor, other than 3 properties that are
important that make the whole animation work.
5. Alignment(Alignment): the initial position of the
child widget.
1. Curve(Curve): In curve animation, easy curves are utilized to modify
the rate of change. This enables both slow and high speeds. There are a
variety of alternatives to choose from.
2. Duration(Duration): Using the duration, we can determine the time
required for a change in alignment.
Let’s see a snippet of how to add an animatedAlign widget in the flutter
app.
6. AnimatedAlign(
alignment: _alignment,
duration: Duration(seconds: 2),
curve: Curves.easeInOutBack,
child: SizedBox(
width: 100.0,
height: 100.0,
child: Image.asset(
'assets/images/pluginIcon.png',
height: 40,
)),
),
As this screen has an image whose arrangement will go from
Alignment.topRight to Alignment.bottomLeft. The duration time is
also set as per our It has the option of the curve. There are many
types of curves. We have used the curves (Curves.easeInOutBack).
7. Let’s see a full example to better understand the AnimatedAlignment
widget.
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
static const _alignments = [
Alignment.topRight,
Alignment.bottomLeft,
];
var _index = 0;
AlignmentGeometry get _alignment => _alignments[_index % _alignments.length];
