Relationships between Constraint expressions.
A Constraint is created by specifying a relationship between two expressions. The Solver tries to satisfy this relationship after the Constraint has been added to it at a set priority.
Constants
- equalTo → Relation
-
The relationship between the left and right hand sides of the expression is
==, (lhs == rhs).const Relation(0) - greaterThanOrEqualTo → Relation
-
The relationship between the left and right hand sides of the expression is
>=, (lhs => rhs).const Relation(2) - lessThanOrEqualTo → Relation
-
The relationship between the left and right hand sides of the expression is
<=, (lhs <= rhs).const Relation(1) - values → List<Relation>
-
A constant List of the values in this enum, in order of their declaration.
const List<Relation>
Properties
- index → int

read-only, inherited - runtimeType → Type
-
A representation of the runtime type of the object.

Operators
-
operator ==(
other) → bool -
The equality operator.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
