📝 Walkthrough

Walkthrough

The bip32_keys package is migrating its hex encoding/decoding dependency from package:hex to package:convert. Two source files update their imports and method calls accordingly (HEX.decode() → hex.decode(), HEX.encode() → hex.encode()), while pubspec.yaml reflects the dependency swap. All functional behavior remains identical.

Changes

Dependency Update packages/bip32_keys/pubspec.yaml	Replaced dependency hex: ^0.2.0 with convert: ^3.1.2 in the dependencies section.
