UnmodifiableListView<E> class
An unmodifiable List view of another List.
The source of the elements may be a List or any Iterable with efficient Iterable.length and Iterable.elementAt.
Constructors
- UnmodifiableListView(Iterable<
E> source) - Creates an unmodifiable list backed by
source. [...]
Properties
- first ↔ E read / write, inherited
- Returns the first element. [...]
- hashCode → int read-only, inherited
- The hash code for this object. [...]
- isEmpty → bool read-only, inherited
- Returns
trueif there are no elements in this collection. [...] - isNotEmpty → bool read-only, inherited
- Returns true if there is at least one element in this collection. [...]
- iterator → Iterator<
E> read-only, inherited - Returns a new
Iteratorthat allows iterating the elements of thisIterable. [...] - last ↔ E read / write, inherited
- Returns the last element. [...]
- length ↔ int read / write, inherited-setter, override-getter
- The number of objects in this list. [...]
- reversed → Iterable<
E> read-only, inherited - An Iterable of the objects in this list in reverse order.
- runtimeType → Type read-only, inherited
- A representation of the runtime type of the object.
- single → E read-only, inherited
- Checks that this iterable has only one element, and returns that element. [...]

test. [...] - insert(
int index, E element) → void inherited - This operation is not supported by an unmodifiable list.
- insertAll(
int at, Iterable< E> iterable) → voidinherited - This operation is not supported by an unmodifiable list.
- join(
[String separator = ""]) → String inherited - Converts each element to a String and concatenates the strings. [...]
- lastIndexOf(
Object? element, [int? start]) → int inherited - The last index of
elementin this list. [...] - lastIndexWhere(
bool test(E element), [int? start]) → int inherited - The last index in the list that satisfies the provided
test. [...] - lastWhere(
bool test(E element), {E orElse()}) → E inherited - Returns the last element that satisfies the given predicate
test. [...] - map<
T> (T f(E element)) → Iterable< T> inherited - Returns a new lazy Iterable with elements that are created by calling
fon each element of thisIterablein iteration order. [...] - noSuchMethod(
Invocation invocation) → dynamic inherited - Invoked when a non-existent method or property is accessed. [...]
- reduce(
E combine(E previousValue, E element)) → E inherited - Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. [...]
- remove(
Object? element) → bool inherited - This operation is not supported by an unmodifiable list.
- removeAt(
int index) → E inherited - This operation is not supported by an unmodifiable list.
- removeLast(
) → E inherited - This operation is not supported by an unmodifiable list.
- removeRange(
int start, int end) → void inherited - This operation is not supported by an unmodifiable list.
- removeWhere(
bool test(E element)) → void inherited - This operation is not supported by an unmodifiable list.
