Do you mean something like this? I call it SVG colorization.

I'll try to squeeze the concept into a short summary. In an SVG file, you need to play around with the <code>fill</code> property as it defines the hex color code.
In terms of programming, you would:
<ol>
<li>Extract the SVG file data as a <code>String</code> variable <code>svgCode</code>.</li>
</ol>
<a href="https://i.stack.imgur.com/YWPIn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YWPIn.png" alt="Illustration of SVG File Data Extraction into String svgCode" /></a>
<ol start="2">
<li>Assign the previous hex color code in <code>previousColor</code> &amp; the currently selected hex color code in <code>newColor</code>.</li>
</ol>
<a href="https://i.stack.imgur.com/svxMz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/svxMz.png" alt="Illustration of hex color code assignment to variables previousColor &amp; newColor" /></a>
<ol start="3">
<li>Apply the <code>String.replaceAll</code> method on <code>svgCode</code> to replace the colors.</li>
</ol>
<a href="https://i.stack.imgur.com/mlNNs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mlNNs.png" alt="Illustration of hex color code replacement" /></a>
<ol start="4">
<li>Update the value of the <code>previousColor</code>.</li>
</ol>
<a href="https://i.stack.imgur.com/zoRbT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zoRbT.png" alt="Illustration of previousColor value updation" /></a>
A more brief elaboration would be
<pre class="lang-dart prettyprint-override"><code>/// Initially without any color selection.
SVGPicture.string('''&lt;svg code with fill #f7ebcb&gt;''');
</code></pre>
<pre class="lang-dart prettyprint-override"><code>/// After the user selects the red color.
SVGPicture.string('''&lt;svg code with fill #FF0000&gt;''');
</code></pre>
<a href="https://zujaj.hashnode.dev/how-to-color-switch-an-svg-in-flutter" rel="nofollow noreferrer">This tutorial</a> can help to solve your issue. Not only does <a href="https://svg-colorization.web.app/" rel="nofollow noreferrer">this app</a> changes the color on runtime, but it also allows the user to download the manipulated SVG code.

I am looking for changing colors of an illustration svg in flutter. I tried flutter_svg package but it support applying only one color to the svg and if I do that svg will be displayed as a single color svg, individual colors are lost. Is there any way to change colors at runtime in flutter for a multi color svg?

How do I apply colors to a multi color svg in flutter?

我正在寻找改变颜色的插画svg在颤音。我尝试了flutter_svg包，但它支持只将一种颜色应用于svg，如果我这样做，svg将显示为单色svg，单个颜色将丢失。对于多色svg，有什么方法可以在运行时改变颜色吗？
