It could be possible trim path animations ?

[SergioEric]

As a sample, we could see rive animation with trim path here

If I understand the concept well, it seems that animations are based on the lines drawn along the vector path.

Since the package only fills vector paths, It won't be possible to implement such a thing... :(

The only eventual solution I see would be clipping animations (from a growing path for example).

Check this

To work as a design, it requires 2 vectors, Fill and Stroke !

The widget code is

// needs, height factor, 2 icons and 2 colors
Stack(
      alignment: Alignment.center,
      children: <Widget>[
        Opacity(
          opacity: 1 - value,
          child: Center(
            child: PathIcon(
              stroke,
              color: Color(0xffCA92F8),
              size: height,
            ),
          ),
        ),
        Positioned(
          bottom: 0,
          child: ClipRect(
            child: Align(
              alignment: Alignment.bottomCenter,
              heightFactor: value,
              child: PathIcon(
                fill,
                color: Color(0xffCA92F8),
                size: height,
              ),
            ),
          ),
        ),
      ],
    )

So, I think this could be a widget inside de package!

Yes ! By composing multiple icons you do several things ! :)
