Install-Package AiForms.Maui.Layouts

This Layout performs wrapping on the boundaries.

• Spacing
  • added between elements
• UniformColumns
  • number for uniform child width (default 0)
  • If it is 0, child elements use their own width.
  • If it is more than 0, a child width will be width which divide parent width by this number.
• IsSquare
  • If it is true, it make item height equal to item width when UniformColumns > 0 (default false)

This Layout automatically scales content to fit within the parent container when it overflows.

• Orientation
  • Direction to fit the content (Vertical or Horizontal)
  • Default: Vertical
  • Vertical
    • When content height exceeds container height, it scales down to 100% minus ScaleMargin.
  • Horizontal
    • When content width exceeds container width, it scales down to 100% minus ScaleMargin.
• EstimatedHeight
  • Expected original height of the content (used when Orientation is Vertical)
  • If not set (-1), content height is measured without constraints.
  • For example, if you specify 600, it assumes a height of 600 for measurement before scaling.
  • Only effective when Orientation: Vertical.
  • Default: -1
• EstimatedWidth
  • Expected original width of the content (used when Orientation is Horizontal)
  • If not set (-1), content width is measured without constraints.
  • For example, if you specify 300, it assumes a width of 300 for measurement before scaling.
    • This is useful when considering text wrapping and similar factors.
  • Only effective when Orientation: Horizontal.
  • Default: -1
• ScaleMargin
  • Margin for scaling to provide extra space when content overflows
  • Value represents the margin ratio (e.g., 0.05 = 5% margin)
  • For example, if 0.05 is specified, it scales down to 95% of the parent content.
  • Default: 0 (0%)
