Breaking changes

Raise the Dart and Flutter baseline

The workspace now builds against Dart 3.13.3 and Flutter 3.47.4, and every package declares that floor instead of the previous Dart 3.12 range. Consumers on older SDKs can no longer resolve these packages, so this release is breaking even though no Dart API changed.

The Flutter floor rises from 3.44 to 3.47 for solana_kit_mobile_wallet_adapter, solana_kit_mobile_wallet_adapter_protocol, and solana_kit_wallet_adapter, matching the floor solana_kit_wallet_ui already required. solana_kit_lints ships the raised floor to consumers, so it carries the same breaking bump. Every other package raises only the Dart SDK floor.

Raising the language version also switches dart format to the tall style, so 83 files across library, test, script, and Codama-generated trees are reflowed. The renderer pipes generated output through dart format, so regenerating stays consistent.

Align your own SDK constraint with the workspace:

environment:
  sdk: ^3.13.0
  # Omit for pure Dart packages; required for the Flutter packages above.
  flutter: ">=3.47.0"

Fixes

Restore complete version inventories in package READMEs

The versions.json data source that renders every package README's installation section had drifted: packages first released after the legacy knope era were never added, so their READMEs told consumers to depend on a bare ^ with no version. The retired solana_kit_functional entry and a stale solana_kit_mobile_wallet_adapter_example version were also lingering.

The inventory now matches every package's pubspec.yaml, the solana_kit_functional key is gone, and the affected installation sections render the real published version again:

dependencies:
  "solana_kit_jupiter": ^0.9.3

Verify both hand-written SHA-256 implementations against an independent hash

solana_kit_anchor and solana_kit_sns each carry their own pure-Dart SHA-256. Anchor uses it to derive program discriminators and SNS to derive name account addresses, so a defect in either changes which instruction or account a program resolves to — a wrong result rather than an exception. Both were covered only by a handful of fixed NIST vectors, which pin the round function but rarely land on the padding and block boundaries where a length bug hides.

Each package now has a sha256_differential_test.dart comparing its implementation against package:crypto (the same dependency solana_kit_addresses already uses). Coverage includes every input length from 0 to 200, which crosses the 55/56-byte padding transitions and the 64-byte block boundary, lengths from 255 through 10000 for multi-block behavior, randomized inputs, and all-zero and all-0xff buffers. Anchor additionally checks instructionDiscriminator against the truncated namespaced digest, and SNS checks getHashedName against sha256("SPL Name Service" + name).

Both implementations agree with the reference on every case. No library behavior changes.

💥 Breaking Change

Add the Solana Name Service client

Add the Solana Name Service client package: .sol domain key derivation (V1/V2 records, subdomains, sub-records), name registry codecs, record V1/V2 address derivation and content codecs, reverse-record helpers, pure-Dart SHA-256, and all protocol program-address constants from the official sns-sdk.

final domainKey = await findDomainKey('mysite');

🐛 Fixed

Harden Pyth and SNS validation

Require the Pyth price-update account signer declared by the receiver IDL, validate Pyth account headers and bounded integer inputs, normalize malformed update data to typed decode errors, and cover the signer requirement through the Surfpool transaction flow. Also enforce SNS record lengths, EVM address sizes, and TLD-trimmed domain-key inputs.
