VarInt class
A VarInt or "Variable Integer" is an integer format used widely in Bitcoin to indicate the lengths of fields within transaction, block and peer-to-peer network data.
A VarInt is a variable length field 1, 3, 5 or 9 bytes in length dependent on the size of the object being defined. The VarInt format is used as it is space efficient over simply using an 8-byte field where variable length objects are used.
Constructors
- VarInt.fromValue(int value)
-
Given an integer value this will be converted into a VarInt.
factory
- VarInt.parse(Uint8List data, {int start = 0})
-
Given an Array of Bytes, parse it and create a VarInt instance from the specified starting index.
