Svg fill animation for a given path
I am trying to animate an arrow from left to right. My arrow path code is below:
<svg id="svg_circle" width="100%" height="100%" viewBox = '0 0 450 400'>
<g transform = "translate(0,0)">
<path class="path" stroke="#F0F0F0" fill="#fff" stroke-width="1" opacity="1" d="m34.97813,21.70979l-33.55223,0.47088l-0.0394,-13.57138l34.2665,-0.47295l-0.0208,-7.14282l14.50618,14.42226l-14.95643,15.04345l-0.20382,-8.74944z" id="svg_1">
<animate id="project_anim1" attributeName="fill" from="#fff" to="#4DAF4C" begin="1s" dur="1s" fill="freeze" repeatCount="1"></animate>
</path>
</g>
</svg>
Above is the content of the SVG path in my arrow.
Please help me how to fill the path from left to right. Waiting for a quick response

You can do this by simply animating <stop>
in <linear gradient>
.
<svg id="svg_circle" width="100%" height="100%" viewBox = '0 0 450 400'>
<defs>
<linearGradient id="left-to-right">
<stop offset="0" stop-color="#4DAF4C">
<animate dur="2s" attributeName="offset" fill="freeze" from="0" to="1" />
</stop>
<stop offset="0" stop-color="#fff">
<animate dur="2s" attributeName="offset" fill="freeze" from="0" to="1" />
</stop>
</linearGradient>
</defs>
<path class="path" stroke="#F0F0F0" fill="url(#left-to-right)" stroke-width="1" opacity="1" d="m34.97813,21.70979l-33.55223,0.47088l-0.0394,-13.57138l34.2665,-0.47295l-0.0208,-7.14282l14.50618,14.42226l-14.95643,15.04345l-0.20382,-8.74944z" id="svg_1" />
</svg>
How it works is that we have a linear gradient representing an abrupt change from green to white. Elements <animation>
move the position of this jump from the left of the arrow (offset = 0) to the right (offset = "1").
Please note that SVG elements <animate>
will not work in IE. If you need to support IE, you will need to use the FakeSmile library or use another method (like the JS animation library).

I don't think this is possible with an attribute fill
. But instead, you can invert the SVG path to a rectangle with a triangular hole. Now you only need the second element behind this path, where you can simply animate the scale in the x direction to fill the hole from left to right.
Here is an image showing the technique:
Here's a working example:
<svg width="100%" height="100%" viewBox='0 0 450 400'>
<rect x="0" y="0" width="1" height="22" style="fill: black;" >
<animateTransform attributeName="transform" type="scale" from="1 1" to="50 1" begin="0s" dur="2s" repeatCount="indefinite" />
</rect>
<path fill="#ffffff" d="M0,0v29.8h86V0H0z M6.5,25V5.5L48.8,25H6.5z"/>
</svg>
Note. The answer has been updated from triangle to arrow, I will not update my answer as the technique is the same for every shape.

Based on andreas ' answer . You can cover your arrow with a shape that is animated to open it.
<svg id="svg_circle" width="450" height="400" viewBox='0 0 450 400'>
<path class="path" stroke="#F0F0F0" fill="#fff"

<animate id="project_anim1" attributeName="fill"

</rect>
