The Wraps Children property controls whether children wrap or stack beyond their container's boundaries when the container's Children Layout is set to Top to Bottom Stack or Left to Right Stack.
If a parent has Wraps children set to true, the wrapping adjusts in response to resizing the parent.
Similarly, resizing a child may result in the stacking changing.
The row height in a Left to Right Stack is determined by the largest child in the row.
Similarly, column width in a Top to bottom Stack is determined by the largest child in the column.
