A fixed-length list of IEEE 754 double-precision binary floating-point numbers that is viewable as a TypedData.

For long lists, this implementation can be considerably more space- and time-efficient than the default List implementation.

Float64List(int length)

Creates a Float64List of the specified length (in elements), all of whose elements are initially zero.

factory
Float64List.fromList(List<double> elements)

Creates a Float64List with the same length as the elements list and copies over the elements.

factory

Operators

operator ==(other) bool

The equality operator.

inherited
operator [](int index) double

Returns the object at the given index in the list or throws a RangeError if index is out of bounds.

operator []=(int index, double value) → void

Sets the value at the given index in the list to value or throws a RangeError if index is out of bounds.

inherited

Methods
