0.9.0 - 2026-08-30

💥 Breaking Change

Sync upstream @solana/kit v8.1.0

Tracks upstream APIs and behavior through v8.1.0:

• solana_kit_transaction_messages (breaking): removed the deprecated compute-unit-limit helpers fillTransactionMessageProvisoryComputeUnitLimit and estimateAndSetComputeUnitLimitFactory, matching upstream @solana/kit's removal of the deprecated @solana/kit estimation helpers (#1948). Use fillTransactionMessageProvisoryResourceLimits and estimateAndSetResourceLimitsFactory instead, which additionally reserve and set the loaded accounts data size limit for version 1 transactions. setTransactionMessageComputeUnitLimit and setTransactionMessageConfig now reject compute unit limits the runtime will not honor — an integer outside [0, 1400000] — throwing SolanaErrorCode.transactionComputeUnitLimitOutOfRange, and reject invalid heap sizes — not a multiple of 1024 bytes in [32768, 262144] — throwing SolanaErrorCode.transactionInvalidHeapSize (upstream #1972). Added the upstream heap-size.ts module as getTransactionMessageHeapSize/setTransactionMessageHeapSize with the same validation, and resource_limit_validation.dart with assertIsValidComputeUnitLimit/assertIsValidHeapSize, minHeapSize, maxHeapSize, and heapSizeMultipleOf. Decoding is unaffected: decompileTransactionMessage still returns messages carrying out-of-range values.

  Migration:

  • fillTransactionMessageProvisoryComputeUnitLimit(m) → fillTransactionMessageProvisoryResourceLimits(m).
  • estimateAndSetComputeUnitLimitFactory(estimate) → estimateAndSetResourceLimitsFactory(estimateResourceLimitsFactory(estimate)).

• solana_kit_transactions (breaking): removed the fixed-size constants transactionPacketSize, transactionPacketHeader, and transactionSizeLimit, matching upstream's removal of TRANSACTION_PACKET_SIZE, TRANSACTION_PACKET_HEADER, and TRANSACTION_SIZE_LIMIT (#1948). Use getTransactionSizeLimit to derive the limit for a specific transaction, or the per-version constants legacyTransactionSizeLimit (1232) and v1TransactionSizeLimit (4096).

  Migration: TRANSACTION_SIZE_LIMIT - getTransactionSize(t) → getTransactionSizeLimit(t) - getTransactionSize(t).

• solana_kit_errors: added the failedToSignTransaction (13) and failedToSignTransactions (14) error codes with upstream messages, plus the transaction codes transactionComputeUnitLimitOutOfRange (5663039) and transactionInvalidHeapSize (5663040) (upstream #1902, #1972).

• solana_kit_instruction_plans: added createFailedToSendTransactionError, createFailedToSendTransactionsError, createFailedToSignTransactionError, createFailedToSignTransactionsError, and createFailedToExecuteTransactionPlanError, mirroring upstream @solana/instruction-plans' transaction-plan-errors.ts (#1902, #1434). The signing factories carry the same non-enumerable transactionPlanResult and optional logs/preflightData context as their sending counterparts, but the message includes no submission-location indicator because signing never submits. The executor now throws through createFailedToExecuteTransactionPlanError.

• solana_kit: added the ClientWithTransactionSending and ClientWithTransactionSigning client interfaces, mirroring upstream @solana/plugin-interfaces (#1899). signTransaction/signTransactions accept the same flexible inputs as their sending counterparts and return signed transactions without submitting them. Sending results guarantee a signature-bearing context; signing makes no default guarantee about the context, matching the upstream TContext parameterization (adapted to Dart's map-based result contexts).

• solana_kit_rpc_transformers (breaking): removed getBigIntDowncastRequestTransformer, matching upstream #1948. It was no longer used by the default Solana RPC request transformer: the Solana RPC transport serializes BigInt values losslessly as large integer literals via stringifyJsonWithBigInts, and Agave parses JSON integers across the full u64 range without precision loss, so downcasting BigInts to (potentially lossy) ints is unnecessary. getDefaultRequestTransformerForSolanaRpc no longer downcasts; if you still need this behavior, recreate it with getTreeWalkerRequestTransformer and a visitor that replaces BigInt nodes with int values.

• solana_kit_rpc_transformers: the numeric allow-list keeps transactionConfig.computeUnitLimit, transactionConfig.heapSize, and transactionConfig.loadedAccountsDataSizeLimit from version 1 transaction responses as numbers instead of upcasting them to BigInt (upstream #1951).

• Documentation now tracks @solana/kit v8.1.0, and the reference pin in config/reference-repos.json moved to bb54243d8a57 (tag v8.1.0).

Migration example:

// Before (removed):
// final estimate = estimateComputeUnitLimitFactory(rpc);
// var message = await estimateAndSetComputeUnitLimitFactory(estimate)(message);
// final freeBytes = transactionSizeLimit - getTransactionSize(transaction);

// After:
final estimate = estimateResourceLimitsFactory(rpc);
var message = await estimateAndSetResourceLimitsFactory(estimate)(message);
final freeBytes =
    getTransactionSizeLimit(transaction) - getTransactionSize(transaction);

🐛 Fixed

Sync upstream @solana/kit v7.1.1

Tracks upstream APIs and behavior through v7.1.1:

• solana_kit: README now documents v7.1.1 as the latest supported upstream version.
• solana_kit_codecs_strings: base-X decoders now report the end of the buffer as the next offset when no bytes remain to decode, matching upstream @solana/codecs-strings (#1926).
• solana_kit_rpc_transformers: subscription responses for blockSubscribe/blockNotification now consult the blockNotifications numeric allow-list, matching upstream @solana/rpc-transformers (#1925).
• solana_kit_instruction_plans: successfulSingleTransactionPlanResultFromTransaction is deprecated in favor of successfulSingleTransactionPlanResult with an explicit context, matching upstream @solana/instruction-plans (#1924).

📖 Documentation

Unslop package docs and code comments

Rewrote every package README from a reader's perspective with verified, compilable examples, removed AI-tell phrasing from docs and code comments, and added a test that analyzes every Dart block in Markdown so examples cannot drift from the API.

💥 Breaking Change

@solana/kit v7.0.0 upstream sync (foundational breaking changes)

Ports the foundational breaking changes from @solana/kit v7.0.0:

• solana_kit_errors: new transactionIntrospection error domain + codes (transactionFailedToDecompileInstructionAccountIndexOutOfRange, transactionIntrospectionCannotDecodeJsonParsedTransaction, transactionIntrospectionUnrecognizedGetTransactionResponse) and instruction-plans max-instructions codes (instructionPlansInvalidMaxInstructionsPerTransaction, instructionPlansMaxInstructionsPerTransactionExceeded).
• solana_kit_codecs_data_structures: createDependentStructDecoder fluent builder for structs whose later fields depend on earlier decoded values.
• solana_kit_instruction_plans: configurable maxInstructionsPerTransaction (default 16, limit 64) on TransactionPlannerConfig, individual TransactionPlanner invocations, and MessagePacker; invocation-specific planner values take precedence without leaking to later calls.
• solana_kit_rpc_types: isSolanaRpcResponse runtime guard.
• solana_kit: removed the local getMinimumBalanceForRentExemption helper (rent exemption is becoming dynamic; use the RPC method instead).
• solana_kit_subscribable: ReactiveStreamStore v7 rewrite — caller-driven connect()/reset()/withSignal(), starts idle, collapses retrying into loading (stale-while-revalidate), renames getUnifiedState() → getState(); removed retry(), value-only getState(), getError(). ReactiveActionStore now passes a fresh CancellationToken to every action, cancels superseded/reset/disposed dispatches, suppresses late outcomes, exposes caller cancellation through withSignal(), and preserves stale results and errors while running.
• solana_kit_transaction_introspection: new first-class package porting @solana/transaction-introspection — RPC transaction decoding, instruction and inner-instruction extraction, loaded-address resolution, and instruction walking helpers; re-exported from the solana_kit umbrella.
• solana_kit_rpc_parsed_types / solana_kit_rpc_transformers / solana_kit_rpc_api: Agave 4.1.0 parsed-account types — vote commissions/latency as int (not BigInt); rent sysvar union (lamportsPerByte vs deprecated burnPercent/exemptionThreshold/ lamportsPerByteYear); stake warmupCooldownRate optional; config slashPenalty/warmupCooldownRate deprecated; keep vote commissions and latency as int in the numeric-keypath allow-lists.

Migration: getMinimumBalanceForRentExemption(space) → rpc.getMinimumBalanceForRentExemption(space).send(); store.retry() → store.connect(); store.getUnifiedState() → store.getState(); the deprecated ReactiveStore/createReactiveStoreFromStreams → createReactiveStreamStore; reactive actions must migrate from (args) async => result to (signal, args) async => result.

// Before
final lamports = getMinimumBalanceForRentExemption(space);
store.retry();
final state = store.getUnifiedState();

// After
final lamports = await rpc.getMinimumBalanceForRentExemption(space).send();
store.connect();
final state = store.getState();

🐛 Fixed

@solana/kit v7.1.0 upstream sync

Ports the @solana/kit v7.1.0 changes into the Dart SDK.

solana_kit_errors

Adds the three new error codes introduced in @solana/kit v7.1.0:

• offchainMessageContentDoesNotMatchExpected (5607018) — from @solana/offchain-messages's new assertOffchainMessageV1Equal helper.
• offchainMessageRequiredSignatoriesDoNotMatchExpected (5607019) — same.
• subscribableStreamClosedWithoutError (8195001) — from @solana/subscribable's new bridgeStoreToAsyncIterable helper.

solana_kit_subscribable

Adds bridgeStoreToAsyncIterable, which adapts a ReactiveStreamStore into a pull-based Stream (the Dart equivalent of the upstream AsyncIterable). It seeds from the store's current snapshot, yields loaded values (latest-wins), throws on error (substituting subscribableStreamClosedWithoutError when the error payload is nullish), and ends cleanly when the CancellationToken fires. The caller owns the store's lifecycle (connect()/reset()).

solana_kit_offchain_messages

Adds assertOffchainMessageV1Equal, which asserts that a version 1 offchain message received from an untrusted signer is the message you expected it to sign. Compares content (reporting UTF-8 byte lengths) and required signatories (order-insensitive, sorted for comparison), throwing offchainMessageContentDoesNotMatchExpected / offchainMessageRequiredSignatoriesDoNotMatchExpected on mismatch.

solana_kit_instruction_plans

createTransactionPlanExecutor's executeTransactionMessage callback may now return the context of a successful result (a map that must include a signature) instead of a Signature or Transaction. The returned context is merged with the mutable context, taking precedence. Returning a Signature or Transaction still behaves as before (stored as context['signature'] / context['transaction'] with the signature derived).

solana_kit_rpc_transformers / solana_kit_rpc_api

• New tokenBalancesConfigs export (accountIndex, uiTokenAmount.decimals, uiTokenAmount.uiAmount).
• getTransaction, getBlock, and simulateTransaction now allow-list uiTokenAmount.uiAmount (previously upcast to BigInt when whole).
• simulateTransaction now allow-lists token-balance accountIndex and uiTokenAmount.decimals.
• getTransaction and getBlock now allow-list the transaction version (previously arrived as 0n while typechecking as 0).
• getTransactionsForAddress allowed-numeric keypaths.

solana_kit

Adds the v7.1.0 client-interface helpers:

• ClientWithGetMinimumBalance and ClientWithFetchAccounts interfaces.
• createClientWithGetMinimumBalanceFromRpc — computes the rent-exempt minimum balance via getMinimumBalanceForRentExemption (with the withoutHeader rate-recovery trick).
• createClientWithFetchAccountsFromRpc — dispatches on address count (getAccountInfo / getMultipleAccounts / empty short-circuit).
• createClientWithInterfacesFromRpc — returns both interfaces.

Also re-exports the @solana/promises helpers as Dart counterparts: isAbortError, getAbortablePromise, and safeRace (adapted to Dart's cancellation model via CancellationToken; AbortError lives in solana_kit_subscribable).

solana_kit_rpc_api

Adds the getTransactionsForAddress RPC method request side: config (commitment, filters, limit, minContextSlot, paginationToken, sortOrder, encoding, maxSupportedTransactionVersion, transactionDetails), filters (blockTime/signature/slot comparisons, status, tokenAccounts), and the params builder.

solana_kit_rpc_types

• Adds the getTransactionsForAddress response types: signatures and full modes (with per-entry base fields, transaction/status variants, and the TransactionDetails enum).
• Adds the shared meta.costUnits field to the transaction meta types.

Already present in the Dart port (no change needed):

• @solana/codecs-data-structures getBitArrayEncoder next-offset fix (offset + size) — the Dart encoder already returns offset + size.
• @solana/transaction-messages compressTransactionMessageUsingAddressLookupTables rejecting v1 transactions — a compile-time-only type narrowing upstream; not expressible in Dart's single-class TransactionMessage model, so no runtime change.

@solana/react changes are not ported (React-only).

0.5.0 - 2026-06-01

💥 Breaking Change

Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

environment:
  sdk: ^3.12.0
