canvasSize

Deprecated

With the chart hosts’ `chartAreaHeight` parameter, the canvas height isn’t necessarily known by the measuring phase, so `MeasuringContext` exposes only `canvasWidth`. When drawing, read the full size from `DrawingContext.canvasSize` instead; if you see this warning while drawing, narrow your receiver from `MeasuringContext` to its subtype `DrawingContext`. If you need the height while measuring and your chart’s height is fixed (e.g., via `Modifier.height`), use that value directly, hoisting it into a constant shared by the modifier and your code. Otherwise, don’t depend on the height here. Until `canvasSize` is removed, `canvasSize.height` stays exact for a pinned height, and for the automatic case, it represents the chart-area height.
