How to Render/User SVG Vector Images in Flutter App
Introduction
SVG (Scalable Vector Graphics) is an XML-based markup language for describing two-dimensional vector graphics. In mobile app development, using SVG images can be beneficial due to their scalability and small file size. However, rendering SVG images in a Flutter app can be a bit complex. This blog post will guide you through the process of rendering SVG vector images in a Flutter app.
What are SVG Images
SVG images are vector graphics that can be scaled up or down without losing their quality. They are widely used in web and mobile development due to their small file size and flexibility. In a Flutter app, you can use SVG images as icons, logos, or even complex graphics.
Rendering SVG Images in Flutter
To render an SVG image in a Flutter app, you can use the `flutter_svg` package. This package provides a widget called `SvgPicture` that can be used to display SVG images.
“`dart
import ‘package:flutter/material.dart’;
import ‘package:fluttersvg/fluttersvg.dart’;
class SvgImageExample extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: SvgPicture.asset(‘assets/image.svg’),
),
);
}
}
“`
Using SVG Images as Icons
You can also use SVG images as icons in your Flutter app. To do this, you can use the `SvgPicture.asset` widget and specify the icon’s size and color.
“`dart
import ‘package:flutter/material.dart’;
import ‘package:fluttersvg/fluttersvg.dart’;
class SvgIconExample extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: SvgPicture.asset(
‘assets/icon.svg’,
width: 24,
height: 24,
color: Colors.blue,
),
),
);
}
}
“`
Adding SVG Images to Your Project
To use SVG images in your Flutter project, you need to add them to your project’s assets. You can do this by adding the following code to your `pubspec.yaml` file:
“`yml
flutter:
assets:
– assets/image.svg
– assets/icon.svg
“`
