  • [IMPROVED] Updated powersync-sqlite-core to v0.3.0, which significantly improves the performance of incremental sync (see details).

v1.8.4

  • [IMPROVED] Added a warning if connector uploadData functions don't process CRUD items completely.

v1.8.3

This version updates powersync-sqlite-core to version 0.2.1 and introduces:

  • [ADDED] Custom User-Agent header and client_id parameter to sync requests.

  • [ADDED] Emit update notifications for watch queries on disconnectAndClear().

  • [IMPROVED] Sync optimizations for MOVE and REMOVE operations. See details in this PR.

  • [IMPROVED] Validate that the powersync-sqlite-core version number is in a compatible range of ^0.2.0.

  • [IMPROVED] Always cast target_op (write checkpoints) to ensure it's an integer.

v1.7.0

  • [IMPROVED] Added a check for the maximum number of columns being exceeded on Table creation.

v1.6.7

  • [FIXED] An issue where apps didn't launch while offline on Windows and Linux. This was achieved by prebundling core binaries.

v1.6.5-6

  • Failed releases. Do not use - use v1.6.7.

v1.6.4

  • [FIXED] hasSynced status now resets correctly after disconnectAndClear has been called.

v.1.6.3

  • [FIXED] Internal: Downgrade the JS dependency and migrate it to devDependencies to resolve a FlutterFlow build error.

v.1.6.2

  • [IMPROVED] For Flutter Web, downloading the required sqlite3.wasm and powersync_db.worker.js files is no longer a manual step. Simply run dart run powersync:setup_web. See the package README for additional details.

v.1.6.1

  • [FIXED] Reintroduced waitForFirstSync.

v.1.6.0

  • [IMPROVED] Flutter Web support. See here for the full announcement.

v1.5.5

  • [FIXED] An issue where hasSynced is cleared when offline.

v1.5.4

  • [FIXED] watch() query parameter triggerOnTables to recognize PowerSync views (ps_).

  • [IMPROVED] Upgraded dependency sqlite_async to version 0.8.1, which adds Navigator locks for more robust multiple tab support.

v1.5.3

v1.5.2

  • [IMPROVED] waitForFirstSync() now iterates through theStream and no longer uses a Future.

  • [FIXED] Sync connection not immediately closed when calling db.disconnect().

v1.5.1

  • [ADDED] hasSynced property to SyncStatus. This becomes true when the client completed at least one full sync.

  • [ADDED] waitForFirstSync which will resolve once the first full sync has completed.

v1.5.0

  • [IMPROVED] Version and dependency upgrades

    • Upgraded sqlite_async to version 0.7.0 and the minimum Dart SDK version to 3.4.0, which fixes the Invalid argument(s): argument value for 'return_value' is null error when closing the database connection.

    • Internal: Updates all the Database types to a CommonDatabase type.

v1.4.2

  • [FIXED] Bad state: Future already completed error when calling disconnect() / disconnectAndClear() multiple times.

v1.4.1

  • Updated powersync_flutter_libs dependency to v0.1.0:

    • [IMPROVED] Updated powersync-sqlite-core on Android to version 0.1.7 which lowers the minSDK to API 21.

v1.4.0

  • [IMPROVED]
    Introduces the use of the powersync-sqlite-core native extension. This is our common Rust core which means all PowerSync SDKs now use the same core logic for PowerSync functionality, improving maintainability and support.

  • [INTERNAL] Added a new package dependency on powersync_flutter_libs for loading the common Rust extension (powersync-sqlite-core).

v1.3.1

v1.3.0

  • [ADDED] crudThrottleTime option to arguments when running PowerSyncDatabase.connect to set the throttle time for CRUD operations.

v1.2.2

  • [IMPROVED] Deprecated the DevConnector and DevCredentials classes. These will be removed in the next major release, at which point it will be a breaking change.

v1.2.1

  • [FIXED] Indexes incorrectly being dropped after the first run.

  • [FIXED] viewName override causing view "..." already exists errors after the first run.

v1.2.0

  • [IMPROVED] The default log output and errors to better assist in debugging.

  • Breaking changes:

    • PowerSyncCredentials constructor is no longer const, and the endpoint URL is validated in the constructor.

    • Different error and exception classes are now used by the library, including CredentialsException, SyncResponseException and PowerSyncProtocolException, instead of more generic AssertionError and HttpException.

  • Other changes:

    • The library now logs to the console in debug builds by default. To get the old behavior, use logger: attachedLogger in the PowerSyncDatabase constructor.

    • Log messages have been improved to better explain the sync process and errors.

v1.1.1

  • [FIXED] An error occasionally occurring when calling powersync.connect() right when opening the database.

  • [IMPROVED] Update getting started docs.

v1.1.0

  • [IMPROVED] Expand SyncStatus to include connected, downloading, and uploading status, and the last errors.

  • [FIXED] Delete operations rejected by the server not being reverted locally.

  • [FIXED] SyncStatus.connected to be updated when calling PowerSyncDatabase.disconnect().

  • [FIXED] Network error messages only containing a single character in some cases.

  • [IMPROVED] Update sqlite_async dependency:

    • Supports catching errors in transactions and continuing the transaction.

    • Add tx.closed and db/tx.getAutoCommit()

  • [IMPROVED] Update uuid dependency:

    • Now uses CryptoRNG from uuid package now that the performance improvements are upstream.

  • Note: This version requires Dart ^3.2.0 / Flutter ^3.16.0.

v1.0.0

  • Use stable version range.

v0.4.2

  • [ADDED] Support for overriding view names, which allows having separate tables for a synced mode and a local-only mode, and moving data between the two.

    • The use case is a user first using the app completely offline (without registering an account) and then potentially at a later stage connecting an account and syncing data, without the upload queue continuously growing in size before that.

    • Includes support for preserving local-only tables when clearing the database: await db.disconnectAndClear(clearLocal: false)

  • [ADDED] Enable SQLite recursive triggers, which allows full-text search functionality.

  • [IMPROVED] Validation of the schema definition now includes checks for invalid characters in names, duplicate columns and indexes, and invalid indexes.

  • [IMPROVED] HTTP error messages now include more details about the error if available.

v0.4.1

  • [IMPROVED] License the entire library under Apache 2.0.

  • [IMPROVED] Update the uuid dependency.

v0.4.0

  • [IMPROVED] Some parameters to PowerSyncCredentials are now optional.

  • [IMPROVED] Update dependencies.
