Variable class
A Variable inside the layout Solver. It represents an indeterminate
in the Expression that is used to create the Constraint. If any entity
is interested in watching updates to the value of this indeterminate,
it can assign a watcher as the owner.
Properties
- hashCode → int
-
The hash code for this object.

- owner → Param?
-
Variables represent state inside the solver. This state is usually of
interest to some entity outside the solver. Such entities can (optionally)
associate themselves with these variables. This means that when solver
is flushed, it is easy to obtain a reference to the entity the variable
is associated with.
no setter
- runtimeType → Type
