Convert your SVG file directly to Flutter paths and prevent all the messing with bezier curves.
Just tap on the Convert SVG button, choose your SVG file and you can obtain the resulting Flutter code from the text field below.
If you want to see realworld example input and output, hit the respective buttons underneath. The examples are the ones from the howto.
Flutter code
Howto
This tutorial describes the usage including the SVG creation using an actual example.
Advantages
- No manual dealing with code that creates bezier paths
- The code that is being returned from the converter is designed to be rather readable (no long numbers with high precision) and can thus be edited afterwards
- The converter supports multiple paths at once in the SVG file
- It softens curves a little
- The boundaries of the existing paths are detected automatically. So no values except for the SVG file need to be provided
- Aside from path nodes in the SVG the converter also converts rect and circle nodes
- Colors are recognized from the shapes and find their representation in the output as well
Caveats
- For the converter to properly convert the SVG into a
Pathit is recommended to put everything to (0,0) of the canvas (except for the paths that are supposed to be shifted) - If padding is desired, a rect should be wrapped around everything with the respective padding towards every shape
- Every group in the SVG should be dissolved before the conversion as it can lead to side-effects
Can you add a copy code button?
Great suggestion! Just added the respective button to the top right of the code container.
This is a fantastic tool. Please keep is alive till Flutter dies.
Well I have no reason to shut it down 🙂
Maybe I could make it open source so that people could also run it offline. Will put this on my list.
If you can share your PayPal email I will sponsor you as much as I could afford.
@marc thanks a lot for such a cool tool. Just have an idea: can you please somehow run MyPainter in inside a Flutter app in the web, so every one can preview result painter on the same page? like here : https://api.flutter.dev/flutter/widgets/Form-class.html (where you have a “Run” button)?
@Andriy
Thank you for your feedback. I will look into that when I’m home. Thank you for your suggestion!
The tool is great!, but it doesn’t seem to account for the height of the canvas, which leads to the correct shape, but smaller than it should be.
“`dart
class MyPainter extends CustomPainter {
@override
void paint(Canvas canvas, Size size) {
Paint paint = Paint();
Path path = Path();
// Path number 1
paint.color = Color(0xff33455B);
path = Path();
path.lineTo(size.width * 0.41, -0.62);
path.cubicTo(size.width * 0.61, -0.61, size.width * 0.59, -0.4, size.width * 0.69, -0.29);
path.cubicTo(size.width * 0.74, -0.23, size.width * 0.83, -0.18, size.width * 0.85, -0.11);
path.cubicTo(size.width * 0.86, -0.03, size.width * 0.81, size.height * 0.04, size.width * 0.75, size.height * 0.11);
path.cubicTo(size.width * 0.66, size.height / 5, size.width * 0.59, size.height * 0.35, size.width * 0.41, size.height * 0.37);
path.cubicTo(size.width * 0.22, size.height * 0.4, 0, size.height * 0.35, -0.11, size.height * 0.24);
path.cubicTo(-0.21, size.height * 0.14, -0.11, size.height * 0.01, -0.06, -0.11);
path.cubicTo(-0.03, -0.19, size.width * 0.04, -0.24, size.width * 0.1, -0.31);
path.cubicTo(size.width / 5, -0.42, size.width * 0.22, -0.63, size.width * 0.41, -0.62);
path.cubicTo(size.width * 0.41, -0.62, size.width * 0.41, -0.62, size.width * 0.41, -0.62);
canvas.drawPath(path, paint);
}
@override
bool shouldRepaint(CustomPainter oldDelegate) {
return true;
}
}

I don’t fully understand your issue.
As you can see, `size.height` does come up in the CustomPainter which means that the height is actually taken into account.
You might need to wrap you CustomPaint widget with a SizedBox to control the height.
I tried it here: https://imgur.com/Fbq5dXZ – this is height 300 and width 300. If I change the height, the proportions change with it.
Hope that helps!
