When to Use double.INFINITY in Flutter

In Flutter, double.INFINITY is a constant that represents positive infinity. It is useful in a few specific scenarios:

1. Setting Constraints with Infinite Size

When creating constraints for a widget, such as with BoxConstraints, you can use double.INFINITY to indicate that the constraint has no limit in a particular dimension. For example:

BoxConstraints(
  minWidth: 100,
  maxWidth: double.INFINITY,
  minHeight: 50,
  maxHeight: double.INFINITY,
)

This sets a minimum width of 100 and a minimum height of 50, but allows the widget to expand infinitely in width and height.

2. Representing Unbounded Values

You can use double.INFINITY to represent values th...
