- Add SVG to assets in pubspec.yaml under flutter > assets

Common flutter_svg Patterns
Real-world SVG usage patterns in Flutter.
- Icon button: IconButton(icon: SvgPicture.asset('assets/icon.svg', width: 24))
- Color override: colorFilter: ColorFilter.mode(Colors.blue, BlendMode.srcIn)
- Network SVG: SvgPicture.network('https://cdn.example.com/icon.svg')
- Placeholder: placeholderBuilder: (context) => CircularProgressIndicator()
- Sized box: wrap in SizedBox(width: 24, height: 24) for precise sizing
Frequently Asked Questions
Does flutter_svg support all SVG features?
flutter_svg supports most path-based SVG: paths, fills, strokes, basic gradients. Unsupported: complex filters, CSS animations, external font references. Keep SVGs simple for reliable Flutter rendering.
How do I use Lottie animations instead of SVG in Flutter?
Install the lottie package. Use Lottie.asset('assets/animation.json') for After Effects-exported animations. Lottie handles complex animations that flutter_svg cannot.
