Card

A material card — an elevated, rounded surface that groups related content.

Example

card(
  elevation: 2,
  content: container(
    padding: 16,
    content: column(
      spacing: 8,
      children: [
        text(value: "Monthly report", style: { size: 18, weight: "w700" }),
        text("Revenue is up 12% over last month."),
        filled_button(content: text("Open"), on_click: ->(_e) { open_report })
      ]
    )
  )
)

Common properties

• content — the card's child control
• elevation
• bgcolor
• shape
• shadow_color
• clip_behavior
• margin
• variant — "elevated", "filled", or "outlined"

Usage

A card wraps a single content control — compose a column/row inside it for multiple children, and pad with a container for inner spacing.
