Methods
-
add(E value)
→ void
-

value to the end of this list,
extending the length by one.
-
addAll(Iterable<E> iterable)
→ void
-

iterable to the end of this list.
-
asMap()
→ Map<int, E>
-
Returns an unmodifiable Map view of
this.
-
clear()
→ void
-
Removes all objects from this list;
the length of the list becomes zero.
-
insert(int index, E element)
→ void
-
Inserts the object at position
index in this list.
-
insertAll(int index, Iterable<E> iterable)
→ void
-
Inserts all objects of
iterable at position index in this list.
-
listUpdated()

-
Notify listener that the list or its values have been updated
-
remove(Object? value)
→ bool
-

removeAt(int index)
→ E
-

index from this list.
-
removeLast()
→ E
-

-
removeWhere(bool test(E element))
→ void
-

test.
-
retainWhere(bool test(E element))
→ void
-
Removes all objects from this list that fail to satisfy
test.
-
shuffle([Random? random])
→ void
-

-
sort([int compare(E a, E b)?])

compare function.
Operators
-
operator +(List<E> other)
→ List<E>
-
Returns the concatenation of this list and
other.
-
operator [](int index)
→ E
-
Returns the object at the given
index in the list
or throws a RangeError if index is out of bounds.
-
operator []=(int index, E value)
→ void
-
Sets the value at the given
index in the list to value
or throws a RangeError if index is out of bounds.
