Bytes class final
Immutable view over [offset, offset + length) of a Uint8List.
- Implemented types
- Available extensions
Constructors
- Bytes.copyOf(Uint8List data, [int start = 0, int? end])
-
Copies a range of
data.factory - Bytes.fromByteBuffer(ByteBuffer buffer)
-
factory
- Bytes.fromByteData(ByteData data)
-
Shares the underlying buffer of
data(zero copy).factory - Bytes.fromBytesLike(BytesLike data)
-
Zero-copy conversion from a BytesLike implementation.
factory
-
Bytes.fromList(List<
int> data) -
Copies
datainto a new buffer.factory - Bytes.fromString(String value)
-
factory
- Bytes.fromTypedData(TypedData data)
-
Zero-copy view over any Dart TypedData.
factory
- Bytes.fromUint8List(Uint8List data)
-
Wraps
datawithout copying. The caller must not mutatedatawhile this view is alive.factory - Bytes.view(Uint8List data, [int offsetInBytes = 0, int? length])
-
Wraps a
Uint8Listview starting atoffsetInBytes.factory

Methods
-
asByteData(
) → ByteData -
Zero-copy
ByteDataview. -
asUint8List(
) → Uint8List -
Zero-copy mutable view. Mutating it mutates the underlying buffer.
override
-
compareTo(
Bytes other) → int -
Lexicographic comparison.
override
-
copyTo(
Uint8List dst, [int start = 0]) → void -
Copies this view into
dststarting atstart. -
getFloat32(
int index, {Endian endian = Endian.big}) → double -
getFloat32Unchecked(
int index, {Endian endian = Endian.big}) → double - Reads a float32 without a bounds check.
-
getFloat64(
int index, {Endian endian = Endian.big}) → double -
getFloat64Unchecked(
int index, {Endian endian = Endian.big}) → double - Reads a float64 without a bounds check.
-
getUint16(
int index, {Endian endian = Endian.big}) → int -
getUint16Unchecked(
int index, {Endian endian = Endian.big}) → int - Reads two bytes without a bounds check.
-
getUint32(
int index, {Endian endian = Endian.big}) → int -
getUint32Unchecked(
int index, {Endian endian = Endian.big}) → int - Reads four bytes without a bounds check.
-
getUint64(
int index, {Endian endian = Endian.big}) → Uint64 -
getUint64Unchecked(
int index, {Endian endian = Endian.big}) → Uint64 - Reads eight bytes without a bounds check.
-
getUint8(
int index) → int -
getUint8Unchecked(
int index) → int - Reads one byte without a bounds check.
-
indexOf(
int value, [int start = 0, int? end]) → int -
Returns the first index of
valuein[start, end), or -1. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
slice(
int start, [int? end]) → Bytes -
O(1) slice.
startandendare relative to this view. -
sublist(
int start, [int? end]) → Bytes - Alias for slice.
-
toBytes(
) → Bytes -
Available on BytesLike, provided by the BytesLikeBytes extension
Zero-copy conversion; returns the same instance when this is already a Bytes. -
toString(
) → String -
A string representation of this object.
override
-
toUint8List(
) → Uint8List -
Explicit copy (Rust's
to_vec).
Operators
-
operator ==(
Object other) → bool -
Content equality (O(n)).
override
-
operator [](
int index) → int - Reads one byte.
