BitStream

BitStream allows for easy manipulation of long strings of bits, for both reading and writing.

It's easy to get started:

var bitstream = BitStream();

You can also start it with a Uint8List:

var bitstream = BitStream(stream: myBytes);

To write to the stream:

bitstream.write(5,bits: 3); //writes 101 (binary) to the stream
bitstream.writeBool(true); //writes 1 (binary) to the stream
bitstream.writeBytes(Uint8List.fromList(<int>[0,255,127]),bytes:3); //writes 0x00FF7F to the stream
bitstream.output(); //will output 1011000000001111111101111111 to the console

Reading is also easy:

bitstream.read(bits:5); //reads 22 (decimal) from the stream
bitstream.read(bits:11); //reads 15 (decimal) from the stream
bitstream.readBool(); //reads true from the stream

Supported Data Types

Data Type	Read Method	Write Method
int	read({bytes, bits})	write(input, {bytes, bits})
bool	readBool()	writeBool(input)
string (ASCII)	readAsciiString({bytes, bits})	writeAsciiString(input, {bytes, bits})
string (HEX)	readHexString({bytes, bits})	writeHexString(input, {bytes, bits})
Uint8List	readBytes({bytes, bits})	writeBytes(input, {bytes, bits})
BitStream	readBitStream({bytes, bits})	writeBitStream(input, {bytes, bits})

Additional Methods

toString()	Returns a binary representation of the current stream
getStream()	Gets the current stream data as a Uint8List
getLength()	Gets the current length of the stream
