+ LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+ ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+ INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES

+ HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+ i. the right to reproduce, adapt, distribute, perform, display,
+ communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+ likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+ subject to the limitations in paragraph 4(a), below;
+ v. rights protecting the extraction, dissemination, use and reuse of data
+ in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+ European Parliament and of the Council of 11 March 1996 on the legal
+ protection of databases, and under any national implementation
+ thereof, including any amended or successor version of such
+ directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+ world based on applicable law or treaty, and any national
+ implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+ surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+ warranties of any kind concerning the Work, express, implied,
+ statutory or otherwise, including without limitation warranties of
+ title, merchantability, fitness for a particular purpose, non
+ infringement, or the absence of latent or other defects, accuracy, or
+ the present or absence of errors, whether or not discoverable, all to
+ the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+ that may apply to the Work or any use thereof, including without
+ limitation any person's Copyright and Related Rights in the Work.
+ Further, Affirmer disclaims responsibility for obtaining any necessary
+ consents, permissions or other rights required for any use of the
+ Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+ party to this document and has no duty or obligation with respect to
+ this CC0 or use of the Work.

+# PowerSync + Django Flutter Demo: Todo List App
+
+Demo app demonstrating use of the PowerSync SDK for Flutter together with the [demo Django backend](https://github.com/powersync-ja/powersync-django-backend-todolist-demo).
+
+# Running the app
+
+Ensure you have [melos](https://melos.invertase.dev/~melos-latest/getting-started) installed.
+
+1. `cd demos/django-todolist`
+2. `melos bootstrap`
+3. `cp lib/app_config_template.dart lib/app_config.dart`
+4. Insert your Django URL and PowerSync project credentials into `lib/app_config.dart` (See instructions below)
+5. `flutter run`
+
+A test user with the following credentials will be available:
+
+```
+username: testuser
+password: testpassword
+```
+
+# Service Configuration
+
+This demo can be used with cloud or local services.
+
+## Local Services
+
+The [Self Hosting Demo](https://github.com/powersync-ja/self-host-demo) repository contains a Docker Compose Django backend demo which can be used with this client.
+See [instructions](https://github.com/powersync-ja/self-host-demo/blob/main/demos/django/README.md) for starting the backend locally.
+
+The backend demo should perform all the required setup automatically.
+
+### Android
+
+Note that Android requires port forwarding of local services. These can be configured with ADB as below:
+
+```bash
+adb reverse tcp:8080 tcp:8080 && adb reverse tcp:6061 tcp:6061
+```
+
+## Cloud Services
+
+### Set up Django project
+
+Follow the instructions in the django backend project's README.
+
+The instructions guide you through the following:
+
+1. Creates `lists` and `todos` tables.
+2. Creates a test user.
+3. Create a logical replication publication called `powersync` for `lists` and `todos`.
+
+### Set up PowerSync Instance
+
+Create a new PowerSync instance by signing up for PowerSync Cloud at www.powersync.com, then connect to the database of your Django project.
+
+Then deploy the following sync rules:
+
+```yaml
+bucket_definitions:
+ user_lists:
+ # Separate bucket per todo list
+ parameters: select id as list_id from lists where owner_id = token_parameters.user_id
+ data:
+ - select * from lists where id = bucket.list_id
+ - select * from todos where list_id = bucket.list_id
+```
+
+### Configure the app
+
+Insert the credentials of your new Django backend and PowerSync projects into `lib/app_config.dart`

+## 1.5.5
+
+ - Fix issue where `hasSynced` is cleared when offline.
+
+## 1.5.4
+
+- Fix watch query parameter `triggerOnTables` to prepend powersync view names.
+- Upgrade dependency `sqlite_async` to version 0.8.1.
+
+## 1.5.3
+
+- Added support for client parameters when connecting.
+
+## 1.5.2
+
+- Refactor `waitForFirstSync()` to iterate through the stream and remove the use of a `Future`.
+- Fix sync connection not immediately closed when calling `db.disconnect()` (#114).
+
+## 1.5.1
+
+- Adds a hasSynced flag to check if initial data has been synced.
+- Adds a waitForFirstSync method to check if the first full sync has completed.
+
+## 1.5.0
+
+- Upgrade minimum Dart SDK constraint to `3.4.0`.
+- Upgrade `sqlite_async` to version 0.7.0 which updates all Database types to use a `CommonDatabase` interface.
+
+## 1.4.2
+
+- Fix `Bad state: Future already completed` error when calling `disconnectAndClear()`.
+
+## 1.4.1
+
+- Upgrades dependency `powersync_flutter_libs` to version `0.1.0`.
+
+## 1.4.0
+
+- 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.
+- Added a new package dependency on `powersync_flutter_libs` for loading the extension.
+
## 1.3.0-alpha.9
- Updated sqlite_async to use Navigator locks for limiting sync stream implementations in multiple tabs
