TextLayer class

The TextLayer widget allows users to add, position, scale, and rotate text on an image. Tapping the text opens a dialog (TextLayerDialog) for further customization, including color, alignment, and background adjustments. The layerData provides properties for the text layer, such as text content, font size, color, position, and rotation. The widget supports both light and dark themes, and the onUpdate callback can be used to trigger actions on update events.
