alpha
Paints the component at alpha of its opacity, content and children alike, cut to the decorated box as androidx's Modifier.alpha cuts it.
The fraction applies to each shape as it is painted, not to the faded area as one image: shapes that overlap inside the faded area show through each other, where a group faded as one image would have hidden the lower shape.
Fades nest: a faded component inside a faded one paints at the product of the two.
Return
this chain with the fade declared on it; 1 decorates nothing.
Parameters
alpha
the fraction of full opacity, from 0 for invisible to 1 for unchanged. A value above 1 paints as 1, and one below 0 or NaN as 0.
