SVGAPlayer is a light-weight animation renderer. You use tools to export svga file from Adobe Animate CC or Adobe After Effects, and then use SVGAPlayer to render animation on mobile application.
SVGAPlayer-Flutter render animation natively via Flutter CustomPainter, brings you a high-performance, low-cost animation experience.
If wonder more information, go to this website.
- SVGAPlayer-Flutter supports 2.0 format only.
Here introduce SVGAPlayer-Flutter usage. Wonder exporting usage? Click here.
dependencies:
svgaplayer_flutter: ^2.0.0 #latest version
SVGAPlayer could load svga file from Flutter local assets directory or remote server. Add file to pubspec.yaml by yourself.
The simplest way to render an animation is to use SVGASimpleImage component.
class MyWidget extends Widget {
@override
Widget build(BuildContext context) {
return Container(
child: SVGASimpleImage(
resUrl: "https://github.com/yyued/SVGA-Samples/blob/master/angel.svga?raw=true"),
);
}
}Animation will run repeatedly. If you wondering a stronger animation controls, use code.
To control an animation rendering, you need to create a SVGAAnimationController instance just like Flutter regular animation. Assign to SVGAImage, load and decode resource using SVGAParser, and then do things as you want with SVGAAnimationController.
import 'package:flutter/material.dart';
import 'package:svgaplayer_flutter/svgaplayer_flutter.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> with SingleTickerProviderStateMixin {
SVGAAnimationController animationController;
@override
void initState() {
this.animationController = SVGAAnimationController(vsync: this);
this.loadAnimation();
super.initState();
}
@override
void dispose() {
this.animationController.dispose();
super.dispose();
}
void loadAnimation() async {
final videoItem = await SVGAParser.shared.decodeFromURL(
"https://github.com/yyued/SVGA-Samples/blob/master/angel.svga?raw=true");
this.animationController.videoItem = videoItem;
this
.animationController
.repeat() // Try to use .forward() .reverse()
.whenComplete(() => this.animationController.videoItem = null);
}
@override
Widget build(BuildContext context) {
return Container(
child: SVGAImage(this.animationController),
);
}
}The MovieEntity will dispose after AnimationController dispose or AnimationController::videoItem reset.
After dispose, the MovieEntity can not reused.
If you eager to reuse the MovieEntity, assign MovieEntity::autorelease to false.
final videoItem = await SVGAParser.shared.decodeFromURL(
"https://github.com/yyued/SVGA-Samples/blob/master/angel.svga?raw=true");
videoItem.autorelease = false;You need to call MovieEntity::dispose() method when no need to use.
We will not manage any caches, you need to use dio or other libraries to handle resource caches.
Use SVGAParser.decodeFromBytes method to decode caching data.
Here are many feature samples.
- Replace an element with Bitmap.
- Add text above an element.
- Hides an element dynamicaly.
- Use a custom drawer for element.
