2.0.0-alpha.28

This release includes bug fixes, Legend updates, and API enhancements.

Breaking changes	Addressed
Minor	#713, #830, #832

The following bugs have been resolved:

• LineCartesianLayer could trigger Bitmap-related IllegalArgumentExceptions.
• ShapeComponent.draw could call Shape.draw twice without rewinding the Path between the calls. (Now, Shape.outline—which replaces Shape.draw, as you’ll learn below—is called only once per ShapeComponent.draw run.)

In HorizontalLegend and VerticalLegend, the items properties and parameters now take ExtraStore lambdas:

Compose

items = rememberExtraLambda(/* ... */) {
    add(LegendItem(/* ... */))
    add(LegendItem(/* ... */))
}

items = rememberExtraLambda(/* ... */) { extraStore ->
    extraStore[seriesDetailKey].forEach { seriesDetails ->
        add(LegendItem(/* ... */))
    }
}

rememberLegendItem has been removed because it’s no longer required.

Views

items = {
    add(LegendItem(/* ... */))
    add(LegendItem(/* ... */))
}

items = { extraStore ->
    extraStore[seriesDetailKey].forEach { seriesDetails ->
        add(LegendItem(/* ... */))
    }
}

The following miscellaneous changes have been made:

Compose

• Component.draw and several protected functions no longer have opacity parameters. Opacity is now handled on the caller side. The functions in question should use the intrinsic opacity (typically 100%).
• In Shape, draw has been replaced with outline. Shapes no longer perform any drawing—they’re responsible only for Path updates. If you’re using Shape.drawable or a custom Shape that draws something else than a Path, use Component or DynamicShader instead.

Views

• The class properties of HorizontalAxis and VerticalAxis are now read-only. Instead of mutating the properties, use the copy functions.
• The LineCartesianLayer.Line.cap property has been removed, but the corresponding constructor parameter remains available.
• Component.draw and several protected functions no longer have opacity parameters. Opacity is now handled on the caller side. The functions in question should use the intrinsic opacity (typically 100%).
• In Shape, draw has been replaced with outline. Shapes no longer perform any drawing—they’re responsible only for Path updates. If you’re using Shape.drawable or a custom Shape that draws something else than a Path, use Component or DynamicShader instead.
