How to Use CBOR Binary Serialization in Dart with File I/O

CBOR is a binary serialization format defined by an standards organization rather than any single programming language, making it highly portable across platforms. Unlike JSON, which stores data as human-readable text, CBOR encodes values in a compact binary format using type tags and data bytes. A developer explored integrating CBOR into a Dart project by creating a sandbox application called 'cboring' and adding the cbor package via Dart's pub tool. The format prefixes each value with a tag byte that identifies the data type, allowing decoders to correctly interpret integers, strings, arrays, and other structures. The tutorial also covers practical Dart file I/O operations such as creating, reading, writing, and deleting files alongside the serialization work.
