Shape Composer Figma plugin

Small plugin that exports custom shapes for use in a Jetpack Compose app.

Essentially, the path data from a Figma VectorNode is translated into Path commands to be recreated in Android, with some extra wrapping around a Shape class to easily copy-paste into the project.

Clover shape example:

val CloverShape: Shape = object: Shape {
    override fun createOutline(
        size: Size,
        layoutDirection: LayoutDirection,
        density: Density
    ): Outline {
        val baseWidth = 200f
        val baseHeight = 200f

        val path = Path()

        path.moveTo(12f, 100f)
        path.cubicTo(12f, 76f, 0f, 77.6142f, 0f, 50f)
        path.cubicTo(0f, 22.3858f, 22.3858f, 0f, 50f, 0f)
        path.cubicTo(77.6142f, 0f, 76f, 12f, 100f, 12f)
        path.cubicTo(124f, 12f, 122.3858f, 0f, 150f, 0f)
        path.cubicTo(177.6142f, 0f, 200f, 22.3858f, 200f, 50f)
        path.cubicTo(200f, 77.6142f, 188f, 76f, 188f, 100f)
        path.cubicTo(188f, 124f, 200f, 122.3858f, 200f, 150f)
        path.cubicTo(200f, 177.6142f, 177.6142f, 200f, 150f, 200f)
        path.cubicTo(122.3858f, 200f, 124f, 188f, 100f, 188f)
        path.cubicTo(76f, 188f, 77.6142f, 200f, 50f, 200f)
        path.cubicTo(22.3858f, 200f, 0f, 177.6142f, 0f, 150f)
        path.cubicTo(0f, 122.3858f, 12f, 124f, 12f, 100f)
        path.close()

        val bounds = RectF()
        val aPath = path.asAndroidPath()
        aPath.computeBounds(bounds, true)
        val scaleMatrix = Matrix()
        scaleMatrix.setScale(
            size.width / baseWidth,
            size.height / baseHeight,
            0f,
            0f
        )
        aPath.transform(scaleMatrix)

        return Outline.Generic(path = aPath.asComposePath())
    }
}

Unsupported path commands:

• Vertical line to (V, v)
• Horizontal line to (H, h)
• Smooth curve to (S, s)
• Smooth quadratic curve to (T, t)
• Elliptical Arc (A, a)

Setup

1. Clone this repo
2. npm install in cloned directory to install dependencies
3. Import plugin for local development in Figma desktop app, using manifest.json
4. Run npm start to start development server and Typescript watcher
5. Use plugin in Figma!

Current designed workflow

1. Select Vector layer in Figma (flatten if necessary)
2. Execute plugin action
3. Paste copied class from clipboard into Compose project
