Overview
The Text Area control is a input-category control in the FS.Skia.UI control suite.
Plain multi-line text entry. It requires the value attribute. It raises onChanged. Its accessibility role is TextBox.
Build it through the FS.Skia.UI.Controls.TextArea module — the typed Props/MVU front door is the
preferred authoring surface (see
Typed control front door). Every
attribute is owned by the model; the control renders against the active Theme,
so its colours, sizing, and density follow the design tokens (see
Controls in the Spec Kit workflow).
Usage example
A runnable example that exercises this control lives in the controls gallery
sample, samples/ControlsGallery/Program.fs. It is compiled as part of the build,
so the example stays in lock-step with the public API.
Preview
A deterministic render-only preview of Text Area (320×160), produced through the
render-only evidence path (Widget.render → SkiaViewer.captureScreenshotEvidence,
ViewerRenderTargetPng) and validated decodable / non-1×1 / non-trivial via
Testing.readPngArtifact. It shows the control rendered against the default
DesignTokens.Light theme.
