Issue: [flutter_svg] width and height properties not working as %
Labels: package,p: flutter_svg

Original report by @grfxjedi on Feb 1, 2019

I'm using svgs generated by MathJax (http://docs.mathjax.org/en/latest/index.html). These files have a very large viewBox and height and width represented in % to scale down. The files render fine in browser. I'm loading the files with SvgPicture.network. In the console I get this output:
`flutter: Warning: Flutter SVG only supports the following formats for `width` and `height` on the SVG root:`
`  width="100%"`
`  width="100px"`
`  width="100" (where the number will be treated as pixels).`
`The supplied value (22.407%) will be discarded and treated as if it had not been specified.`

flutter: Warning: Flutter SVG only supports the following formats for `width` and `height` on the SVG root:`
`  width="100%"
`  width="100px"
`  width="100" (where the number will be treated as pixels).`
`The supplied value (5.009%) will be discarded and treated as if it had not been specified.`

It looks to me like the % values are being ignored and treated as pixels. This is throwing the size of the images way off. They are huge and I have to scale them down. The problem with this is that I'm displaying several images at once that are not the same size, so they scale differently to fill the boxes, making some of them zoomed in more than others.

Please let me know if this is a bug in the plugin or if I should be doing something differently.

This is my dart code:
`child: SvgPicture.network(`
`  '$svgUrl$equation', // dynamically generated url`
`  height: 50,`
`  color: Colors.indigo,`
`  alignment: Alignment.topLeft,`
`  fit: BoxFit.contain,`
`),`

This is a sample svg file:

This is a bug, but I'm not entirely sure about the best way to fix it.

The error text is misleading.  Percentages are not supported in a bunch of places - the support is inconsistent.  I could try to make it more consistent, but  on the root object itself I'm not sure how to make sense of that.  Do you expect your drawing to be a percentage of the available screen?  The SvgPicture widget?  somethign else?

I would expect the percentages to be relative to the available space. Like in a web browser, if you just open an svg file with %, it will be based on the browser window. If you have the image constrained inside a div, the percentage is based on the size of that div. So an example in flutter, say you have a container widget is 200px wide and the svgs width is set to 50%, I would expect the svg to render at a width of 100px. Or if you had two columns with flex widths 1 and 2, then you put that same svg (width 100%) in each, that the svgs would scale similarly filling half the space of each column.

Hi Dan,
svg with defined width and height, but having rect with width and height in percentage would throw exception.

Any suggestion to get the parentNode attribute so that it can calculate the percentage based on that?

sample:
<svg xmlns=\"http://www.w3.org/2000/svg\" width=\"150\" height=\"50\">**<rect width=\"100%\" height=\"100%\" fill=\"#f5f7fa\"/>**<path fill=\"#e584b5\" d=\"M27.38 12.75L26.93 13.45L25.60 13.49L25.49 13.38Q25.10 13.66 24.69 13.49L24.56 13.36L19.47 13.94L18.95 14.78L18.87 14.70Q19.37 17.42 26.25 17.31L26.20 17.27L26.27 17.33Q24.41 20.13 22.19 21.21L22.14 21.16L22.11 23.63L23.40 24.45L23.55 24.59Q26.42 23.09 29.37 23.37L29.48 23.49L29.48 24.38L29.46 24.36Q30.68 25.03 29.43 27.98L29.48 28.03L28.22 28.14L28.21 28.13Q25.99 31.71 22.07 31.99L22.17 32.10L22.19 32.11Q20.85 33.04 19.19 32.97L19.10 32.88L19.22 33.01Q18.37 33.91 18.44 35.16L18.57 35.29L19.62 36.36L19.66 36.40Q20.78 36.14 21.62 35.62L21.71 35.71L24.02 35.74L24.32 34.68L24.49 34.85Q28.44 33.65 30.14 30.52L30.06 30.44L30.14 30.52Q34.29 27.17 30.82 21.20L30.66 21.04L30.81 21.19Q29.12 21.03 28.09 20.29L28.11 20.31L27.94 20.14Q34.52 14.01 28.44 13.60L28.48 13.64L27.40 12.77Z\"/><path fill=\"#dd54dd\" d=\"M116.07 12.76L115.94 12.63Q114.02 13.39 112.47 13.37L112.43 13.33L112.33 13.23Q105.57 20.67 107.91 29.56L107.93 29.59L109.25 29.78L109.33 29.86Q109.65 30.93 108.54 30.75L108.47 30.68L108.49 31.83L110.44 32.39L110.37 32.32Q109.52 33.68 113.16 36.22L113.19 36.25L115.47 36.29L117.41 36.27L118.28 36.29L118.32 36.33Q118.76 33.60 121.55 33.94L121.68 34.07L121.84 32.55L122.28 32.45L123.00 31.77L122.82 30.17L122.81 30.17Q124.54 27.35 124.16 24.51L124.19 24.53L125.09 24.31L125.00 23.37L124.94 23.31Q124.74 23.00 124.77 22.58L124.62 22.44L124.81 21.78L124.75 21.71Q123.76 19.93 123.78 18.51L123.92 18.66L123.94 18.67Q122.18 16.36 121.93 14.41L121.88 14.36L121.87 14.36Q119.99 14.24 118.93 13.10L118.78 12.95L118.87 13.04Q117.32 13.08 116.02 12.71L116.12 12.80ZM113.60 17.30L113.58 17.28Q119.38 16.70 120.42 21.87L120.47 21.92L120.45 21.90Q121.03 22.32 121.45 22.06L121.36 21.97L121.26 21.87Q122.30 27.56 119.34 31.75L119.35 31.76L119.37 31.77Q117.16 33.73 114.87 32.32L115.00 32.45L114.95 32.40Q114.16 33.52 113.49 32.34L113.43 32.29L113.49 32.35Q111.30 32.30 111.19 30.05L111.17 30.03L111.26 30.12Q109.95 29.96 109.07 29.32L109.10 29.34L109.65 28.49L109.52 28.36Q108.44 24.20 110.38 21.94L110.40 21.97L110.51 22.07Q110.39 18.34 113.41 17.11L113.50 17.20Z\"/><path fill=\"#eb734b\" d=\"M54.31 12.63L54.33 12.65Q47.09 15.30 48.04 22.60L47.97 22.53L48.06 22.61Q49.61 23.93 50.14 25.64L50.17 25.66L50.09 25.58Q55.09 26.78 58.80 24.89L58.80 24.89L59.67 26.21L59.49 26.04Q57.04 32.47 51.15 33.47L51.19 33.52L51.00 33.32Q50.00 34.79 50.23 36.32L50.14 36.23L50.22 36.31Q56.77 35.39 58.77 29.56L58.94 29.73L58.90 29.69Q61.41 27.80 60.77 24.97L60.73 24.92L61.17 25.14L61.29 25.25Q62.53 21.37 60.77 18.61L60.75 18.58L60.80 18.64Q60.54 13.04 54.31 12.63L54.47 12.79ZM53.04 16.31L53.01 16.27Q54.41 16.37 55.59 16.26L55.67 16.33L55.63 16.30Q56.39 17.48 57.92 17.41L57.86 17.35L57.89 17.39Q61.56 25.52 52.26 23.76L52.31 23.80L52.20 23.69Q51.31 22.04 50.31 21.10L50.44 21.23L50.32 21.11Q50.08 17.34 52.97 16.23L52.94 16.20Z\"/><path d=\"M3 28 C70 15,72 7,142 34\" stroke=\"#6d89dd\" fill=\"none\"/><path fill=\"#a570db\" d=\"M86.46 12.64L86.00 13.31L84.78 13.47L84.69 13.38Q84.19 13.55 83.78 13.38L83.76 13.36L78.50 13.77L78.18 14.81L78.14 14.77Q78.49 17.34 85.36 17.23L85.39 17.26L85.34 17.21Q83.61 20.13 81.39 21.21L81.34 21.16L81.24 23.56L82.66 24.51L82.65 24.50Q85.72 23.19 88.67 23.48L88.57 23.37L88.69 24.39L88.68 24.39Q89.92 25.07 88.67 28.02L88.65 28.00L87.35 28.08L87.47 28.20Q85.31 31.83 81.39 32.11L81.36 32.08L81.38 32.11Q79.97 32.96 78.31 32.89L78.42 33.00L78.36 32.94Q77.72 34.05 77.78 35.30L77.75 35.27L78.73 36.26L78.88 36.42Q79.93 36.09 80.77 35.57L80.82 35.62L83.19 35.71L83.66 34.82L83.53 34.69Q87.51 33.52 89.22 30.39L89.28 30.46L89.35 30.53Q93.49 27.16 90.02 21.20L89.94 21.11L90.04 21.22Q88.24 20.95 87.21 20.21L87.12 20.13L87.25 20.26Q93.72 14.01 87.65 13.60L87.67 13.63L86.63 12.81Z\"/></svg>

Comment by @4handheld on Jan 20, 2020
Seems like the width and height attributes in the SVG file are responsible. Setting the values from 512 to 100 resolved the issue in my app.  ie, from
`<svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
	 viewBox="0 0 512 512" style="enable-background:new 0 0 512 512;" xml:space="preserve">`
to 
`<svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"

Comment by @ZeeshanFareed123 on Feb 12, 2020
Fixed this warning by the following steps:
1. Open SVG image in android studio.
2. Change the width and height from "512px" to "256px"


---
Comment by @alvindrakes on Mar 2, 2020
@ZeeshanFareed123  Yeap, I tried this solution and it works.
But will the SVG look pixelated on a bigger screen? 
Since we specify it to 256px. 

---
Comment by @shafi49 on May 19, 2020
@ZeeshanFareed123 you are right. This error comes if it finds any values set as points instead of pixel or percentage. Please convert your points unit (pt) to pixels or percentage. I recommend using pixels. 
1 pt = 1.333px. There are many handy converters out there too. [Here is one](https://www.ninjaunits.com/converters/pixels/points-pixels/)

For example I changed this code
````
<svg height="384pt" viewBox="0 0 384.024 384" width="384pt" xmlns="http://www.w3.org/2000/svg">
````
to this

````
<svg height="512px" viewBox="0 0 384.024 384" width="512px" xmlns="http://www.w3.org/2000/svg">
````

Hope it helps.

Comment by @Dlouki on Dec 11, 2020
this is code is work just change   height="512pt" to  height="512px" and width="384pt" to width="384px"

Comment by @marcellocamara on Dec 17, 2020
I solved all this warnings removing the unity from height and width. 

Example: 
```
height="512pt" => height="512"
or
height="512px" => height="512"
```

worked for me. I didn't change the numbers(values), just change (pt) to (px).

Comment by @amkuchta on Mar 5, 2021
Converting `pt` to `px` or removing the "type" of measurement altogether isn't always an option.  For example, using `FractionallySizeBox` as follows

```dart
FractionallySizedBox(
  heightFactor: 0.75,
  child: SvgPicture.asset(
    'assets/images/mendala.svg',
    color: Colors.white,
    semanticsLabel: 'A white mendala',
  ),
)
```

results in the following output:

```

I/flutter ( 5455):   width="100%"

Comment by @lojithv on Jun 5, 2021
I found a solution for this.

**Steps**
1. Wrap svg icon inside a container. ( Container should be a child widget)
2. Set color of the container to transparent.
3. Change the size of the container. (Svg icon inhert the size of parent widget.)

**Example**

Comment by @followthemoney1 on Jun 8, 2021
only this was help for web when I was trying to set height or width:
```
FractionallySizedBox(
                    heightFactor: procentIconSize,
                    child: SvgPicture.asset(
                      assetName,
                      semanticsLabel: sectionName,
                      color: Colors.white,
                      
                    ),
```

and no matter what icons size was:
```
<svg width="1477px" height="1884px" viewBox="0 0 1477 1884" 
```
or
```
<svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"

Remove height="422pt" and  width="422pt"

Comment by @brunoalfred on Aug 22, 2021
I face the same challenge but here is a simple workaround over the issue:

Steps:
🔥☄️
1. Go to your svg file and check the units used to specify `height` and `width` of  your svg asset.
2. Make sure the units are either of these options;  %,  px  
    ie change from width="100pt" to (width="100px" or width="100%" or width="100")
3. Rebuild your application and the error must have gone away.
4. Enjoy 🏃🏽‍♂️ flutter_svg
