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.
Constructors
Properties
- name → String
-
An optional name given to the variable. This is useful in debugging Solver state.
read / write - 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.
read-only - value → double
-
The current value of the variable.
read / write - hashCode → int
-
Get a hash code for this object.
read-only, inherited - runtimeType → Type
-
A representation of the runtime type of the object.

Invoked when a non-existent method or property is accessed.
inherited -
toString(
) → String -
