RealmResults<T extends Object?> class Realm

Instances of this class are live collections and will update as new elements are either added to or deleted from the Realm that match the underlying query.

inherited
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(covariant T element) → bool
true if the Results collection contains the specified element.
override
elementAt(int index) → T
Returns the element of type T at the specified index.
override
every(bool test(T element)) → bool

inherited
expand<T>(Iterable<T> toElements(T element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(T element), {T orElse()?}) → T
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, T element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<T> other) → Iterable<T>

inherited
freeze() → RealmResults<T>
Creates a frozen snapshot of this query.
indexOf(covariant T element, [int start = 0]) → int
Returns the index of the first occurrence of the specified element in this collection, or -1 if the collection does not contain the element.
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(T element), {T orElse()?}) → T

inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(T combine(T value, T element)) → T
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
