How much space space should be occupied in the main axis.
During a flex layout, available space along the main axis is allocated to children. After allocating space, there might be some remaining free space. This value controls whether to maximize or minimize the amount of free space, subject to the incoming layout constraints.
See Row, Column, MainAxisAlignment, Flexible.
Constants
- max → MainAxisSize
-
Maximize the amount of free space along the main axis, subject to the incoming layout constraints.
If the incoming layout constraints have a small enough BoxConstraints.maxWidth or BoxConstraints.maxHeight, there might still be no free space.
const MainAxisSize(1) - min → MainAxisSize
-
Minimize the amount of free space along the main axis, subject to the incoming layout constraints.
If the incoming layout constraints have a large enough BoxConstraints.minWidth or BoxConstraints.minHeight, there might still be a non-zero amount of free space.
const MainAxisSize(0) - values → List<MainAxisSize>
-
A constant List of the values in this enum, in order of their declaration.
const List<MainAxisSize>
