bip329_labels 2.0.0

A Dart implementation for Flutter of BIP-329: Wallet Labels Export Format for Bitcoin wallets.

2.0.0

• Breaking — OutputLabel.spendable is now bool? (was required bool): per BIP-329 spendable is optional and "if omitted, the importing wallet should not alter these values", so an omitted spendable now parses to null (the spec's "do not alter" state) instead of throwing — previously a valid BIP-329 output record without spendable failed to parse. Consumers reading the field must handle null (e.g. check spendable == false for an explicitly do-not-spend output).
• Serialization omits null/absent fields (ignoreNull): optional fields that are null are no longer emitted as "field": null; they are omitted, matching the spec's examples, and an absent spendable round-trips as absent.
• Tooling: SDK floor raised to Dart ^3.8.0 (minimum required by flutter_lints ^6.0.0); dart_mappable runtime constraint unchanged (^4.6.0) so consumer compatibility is otherwise preserved.
