A fixed-length list of IEEE 754 single-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.

if there are no elements in this collection.… - isNotEmpty → bool

Iterator
that allows iterating the elements of thisIterable

Returns the offset in bytes into the underlying byte buffer of this view.
- reversed → Iterable<double>

Returns an
Iterable

Constructors
- Float32List(int length)
-
Creates a Float32List of the specified length (in elements), all of whose elements are initially zero.
- Float32List.fromList(List<double> elements)
-
Creates a Float32List with the same length as the
elements
list and copies over the elements. - Float32List.view(ByteBuffer buffer, [int offsetInBytes = 0, int length])
-
Creates a Float32List view of the specified region in the specified byte buffer. Changes in the Float32List will be visible in the byte buffer and vice versa. If the
offsetInBytes
index of the region is not specified, it defaults to zero (the first byte in the byte buffer). If the length is not specified, it defaults to null, which indicates that the view extends to the end of the byte buffer.…
Operators
-
operator [](
int index) → double -
inherited
Returns the object at the given
index

is out of bounds. -
operator []=(
int index, double value) → void -
inherited
Sets the value at the given
index
in the list tovalue
or throws a RangeError ifindex
is out of bounds.
