Flutter SVG rendering - dart

Question

I tried adding an image with a SVG source to my flutter application.
new AssetImage("assets/images/candle.svg"))
But I didn't get any visual feedback.
How can I render an SVG picture in Flutter?

Answer 1

Fonts are a great option for a lot of cases.
I've been working on a library to render SVGs on a canvas, available here:
https://github.com/dnfield/flutter_svg
The API as of right now would look something like
new SvgPicture.asset('asset_name.svg')
to render asset_name.svg (sized to its parent, e.g. a SizedBox). You can also specify a color and blendMode for tinting the asset..
It's now available on pub and works with a minimum of Flutter version 0.3.6. It handles a bunch of cases but not everything - see the GitHub repo for updates and to file issues.
The original GitHub issue referenced by Colin Jackson is really not meant to be primarily focused on SVG in Flutter. I opened another issue here for that: https://github.com/flutter/flutter/issues/15501

Answer 2

Flutter does not currently support SVG. Follow issue 1831 for updates.
If you absolutely need vector drawing you can see the Flutter Logo widget as an example of how to draw using the Canvas API, or rasterize your image on the native side and pass it to Flutter as a bitmap, but for now your best bet is probably to embed high-resolution rasterized asset images.

Answer 3

Developers from the Flutter community created a lib to handle svg files. We can use it as
new SvgPicture.asset(
'assets/images/candle.svg',
height: 20.0,
width: 20.0,
allowDrawingOutsideViewBox: true,
),
I found a small example of SVG implementation here.

Answer 4

The work around for now is use fonts
https://icomoon.io/
fonts:
- family: icomoon
fonts:
- asset: assets/fonts/icomoon.ttf
Useage
static const IconData TabBarHome= const IconData(0xe906, fontFamily: 'icomoon');
static const IconData TabBarExplore= const IconData(0xe902, fontFamily: 'icomoon');
Replace the ### eg (906)

Answer 5

You can follow the below steps
- visit http://fluttericon.com
- upload your SVG icons
- click on download button
- you will get two files
1. iconname.dart 2. iconname.ttf font file
- use this file in flutter & import iconname.dart

Answer 6

step 1. add dependency in your pubspec.yaml
dependencies:
flutter_svg: any
the Advantage of version any is you can use in any SDK version
but dependencies version is most important so add suitable version for your dependency.
step 2. import the flutter svg package in your app
import 'package:flutter_svg/flutter_svg.dart';
step 3. just use like below
SvgPicture.asset(
'assets/images/bm-icon1.svg',
width: 18.0,
height: 18.0,
),

Answer 7

You can use this library for rendering SVG Images - https://pub.dev/packages/flutter_svg
Example -
Container(
child: SvgPicture.asset("assets/images/yourImage.svg")
)

Answer 8

I solved similar problem by converting the svg images to ttf at fluttericon.com.
These are the steps involved.
Keep all your svg files in a folder.
Upload all of them to fluttericon by using the uploader there.
You can select all of them and drag and drop at the spot.
Give your icons a dart class name at the top: like, Svgicons
Select all your icons and press Download.
It will download a zip file with a dart file and fonts folder which contains Svgicons.ttf.
copy the fonts folder to your project folder and refer to it as an asset in pubspec.yaml.
fonts:
- family: Svgicons
fonts:
- asset: fonts/Svgicons.ttf
import the svgicons_icons.dart where you are going to use the images.
Sample:
import '../svgicons_icons.dart';
import 'social_media.dart';
class SocialMediaRepository {
List<SocialMedia> getSocialMedia = [
SocialMedia(id: 1, title: "Facebook", iconAsset:Svgicons.facebook, isFavorite: false),
SocialMedia(id: 2, title: "Instagram", iconAsset: Svgicons.instagram, isFavorite: false),
SocialMedia(id: 3, title: "LinkedIn", iconAsset: Svgicons.linkedin, isFavorite: false),
....
Here iconAsset is of type IconData which used to be a String referring to the svg image originally.
Display the ttf by using
...
Icon(item.iconAsset),
SizedBox(width: 10),
Text(item.title),
],
),
where item is the object containing IconData.
Now you can remove the reference to svg images from the project.

You can use flare to create animations and just import .flr as an asset
import 'package:flare_flutter/flare_actor.dart';
class MyHomePage extends StatefulWidget {
#override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return new FlareActor("assets/Filip.flr", alignment:Alignment.center, fit:BoxFit.contain, animation:"idle");
}
}

Answer 10

Of possible interest: There's a newer Flutter SVG library called jovial_svg. I wrote it to handle a more robust subset of SVG than what I was able to find on pub.dev at the time. While I was at it, I also made a binary format that SVG assets can be compiled to. It's a little more compact, and about 10x faster to read, so it's a good choice for assets you package with your application.
The library is at https://pub.dev/packages/jovial_svg

Answer 11

flutter support special type of svg
if have style tag then not load svg image in flutter
flutter support inline styling in svg

Answer 12

Svg in flutter https://pub.dev/packages/flutter_svg
add package in pubspec.yaml
dependencies:
flutter_svg: any
assets:
-assets/images/
to insert svg.
SvgPicture.asset('assets/images/password-icon.svg',
width: 24, height: 29.2),
