Block class abstract mixin

A class representing an efficient container for binary data.

Block provides a way to handle binary data with memory efficiency and various access patterns. It supports lazy initialization, caching, and slicing operations.

Constructors

Block(Builder builder)

Creates a new Block from a builder function.

factory

Block.empty()

Creates an empty Block with size 0.

factory

Block.fromBytes(Iterable<Uint8List> bags)

Creates a Block from a collection of byte arrays.

factory

Block.fromStream(Stream<Uint8List> stream, int size)

Creates a Block from a stream of byte arrays.

factory

Block.fromString(Iterable<String> bags, {Encoding encoding = utf8})

Methods

bytes() → Future<Uint8List>

Returns a Future that completes with the entire block's content as a single Uint8List.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

slice(int start, [int? end]) → Block

Creates a new Block that is a slice of this block, from start to end.

stream() → Stream<Uint8List>

Returns a stream of binary data chunks contained in this block.

text() → Future<String>

Returns a Future that completes with the entire block's content as a UTF-8 decoded string.

toString() → String

A string representation of this object.
