StackFit enum
How to size the non-positioned children of a Stack.
This enum is used with Stack.fit and RenderStack.fit to control how the BoxConstraints passed from the stack's parent to the stack's child are adjusted.
See also:
- Stack, the widget that uses this.
- RenderStack, the render object that implements the stack algorithm.
Constants
- expand → const StackFit
-
The constraints passed to the stack from its parent are tightened to the biggest size allowed.
For example, if the stack has loose constraints with a width in the range 10 to 100 and a height in the range 0 to 600, then the non-positioned children of the stack would all be sized as 100 pixels wide and 600 high.
const StackFit(1) - loose → const StackFit
-
The constraints passed to the stack from its parent are loosened.
For example, if the stack has constraints that force it to 350x600, then this would allow the non-positioned children of the stack to have any width from zero to 350 and any height from zero to 600.
See also:
- Center, which loosens the constraints passed to its child and then centers the child in itself.
- BoxConstraints.loosen, which implements the loosening of box constraints.
const StackFit(0) - passthrough → const StackFit
-
The constraints passed to the stack from its parent are passed unmodified to the non-positioned children.
For example, if a Stack is an Expanded child of a Row, the horizontal constraints will be tight and the vertical constraints will be loose.
const StackFit(2) -
values
→ const List<
StackFit> -
A constant List of the values in this enum, in order of their declaration.
