operator == method
The equality operator.
The default behavior for all Objects is to return true if and
only if this object and other
are the same object.
Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:
-
Total: It must return a boolean for all arguments. It should never throw.
-
Reflexive: For all objects
o
,o == o
must be true. -
Symmetric: For all objects
o1
ando2
,o1 == o2
ando2 == o1
must either both be true, or both be false. -
Transitive: For all objects
o1
,o2
, ando3
, ifo1 == o2
ando2 == o3
are true, theno1 == o3
must be true.
The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.
If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.
Implementation
@override
bool operator ==(Object other) {
if (other.runtimeType != runtimeType) return false;
// Warning: make sure these properties are in the exact same order as in
// hashValues() and in the raw constructor and in the order of fields in
// the class and in the lerp() method.
return other is TimelineThemeData &&
other.direction == direction &&
other.color == color &&
other.nodePosition == nodePosition &&
other.nodeItemOverlap == nodeItemOverlap &&
other.indicatorPosition == indicatorPosition &&
other.indicatorTheme == indicatorTheme &&
other.connectorTheme == connectorTheme;
