Pair<T1, T2> class

A class that stores a pair of values.

In the C++ STL, std::pair is defined in <utility>. It provides a way to store two heterogeneous objects as a single unit.

Available extensions

Constructors

Pair(T1 first, T2 second): Creates a Pair grouping the first and second values dynamically.
Pair.fromMapEntry(MapEntry<T1, T2> entry): Creates a Pair from a MapEntry.
Pair.fromRecord((T1, T2) record): Creates a Pair from a modern Dart 3 Record.

first ↔ T1: The first element of the pair.
getter/setter pair
hashCode → int: The hash code for this object.
no setteroverride
record → (T1, T2): Returns the pair as a modern Dart 3 Record for easy destructuring. Example: var (a, b) = myPair.record;
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
second ↔ T2: The second element of the pair.
getter/setter pair

clone() → Pair<T1, T2>: Creates a shallow clone of the Pair.
compareTo(Pair<T1, T2> other) → int: Available on Pair<T1, T2>, provided by the ComparablePair extension
Compares this pair lexicographically with other.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
swap(Pair<T1, T2> other) → void: Exchanges the contents of this pair with those of other.
toList() → List: Returns the elements as a standard Dart List.
toMapEntry() → MapEntry<T1, T2>: Returns the pair as a MapEntry, making it perfectly compatible with Dart Maps.
toString() → String: A string representation of this object.
override

operator <(Pair<T1, T2> other) → bool: Available on Pair<T1, T2>, provided by the ComparablePair extension
Returns whether this pair is lexicographically less than other.
operator <=(Pair<T1, T2> other) → bool: Available on Pair<T1, T2>, provided by the ComparablePair extension
Returns whether this pair is lexicographically less than or equal to other.
operator ==(Object other) → bool: The equality operator.
override
operator >(Pair<T1, T2> other) → bool: Available on Pair<T1, T2>, provided by the ComparablePair extension
Returns whether this pair is lexicographically greater than other.
operator >=(Pair<T1, T2> other) → bool: Available on Pair<T1, T2>, provided by the ComparablePair extension
Returns whether this pair is lexicographically greater than or equal to other.
