computeSize abstract method

double computeSize({
  1. required ParentLayout parent,
  2. required ChildLayout child,
  3. required LayoutHandle<Layout> layoutHandle,
  4. required LayoutAxis axis,
  5. required LayoutSize contentSize,
  6. required LayoutSize viewportSize,
})

Computes the actual size value for this unit.

The calculation considers the parent layout context, child properties, layout axis, content size, and viewport constraints to determine the final size.

Parameters:

  • parent: The parent layout providing context and constraints
  • child: The child element being sized
  • layoutHandle: Handle for layout operations
  • axis: The axis along which sizing is calculated
  • contentSize: The natural size of the content
  • viewportSize: The available viewport size

Returns the computed size value.

Implementation

double computeSize({
  required ParentLayout parent,
  required ChildLayout child,
  required LayoutHandle layoutHandle,
  required LayoutAxis axis,
  required LayoutSize contentSize,
  required LayoutSize viewportSize,
});
