Verify compatibility with the major version bump
The
parse_server_sdkdependency has been upgraded from^6.4.0to^8.0.0, which is a major version bump. This suggests breaking changes could be present in the API.

Confirm API compatibility for parse_server_sdk v8.0.0
No changelog or release notes could be found for v8.0.0 in the upstream Parse-SDK-Flutter repository, and the major bump from ^6.4.0 to ^8.0.0 likely introduces breaking changes. Please manually review and test before merging:
• Inspect the upstream repo (commits or code diff) between v6.x and v8.x for renamed or removed APIs
• Verify that everyparse_server_sdkcall in your code still compiles and behaves as expected
• Run or update integration/unit tests against SDK 8.0.0 to catch breaking changes earlypackages/dart/pubspec.yaml (2)

Verify compatibility with mime and timezone major version upgrades
Both
mime(^1.0.0 to ^2.0.0) andtimezone(^0.9.4 to ^0.10.1) have been upgraded to new major versions, which could introduce breaking changes.

These three "prefer_const_" lints were removed to simplify constant usage recommendations in Flutter projects, as they were sometimes seen as overly restrictive[1][4].
Removed in 4.0.0 (Still Absent in 5.0.0)
package_prefixed_library_nameslibrary_names
These were already removed in the shift from 3.0.2 to 4.0.0[1].
Added in 4.0.0 (Still Present Unless Otherwise Stated)
library_annotationsno_wildcard_variable_uses
What This Means for Your Project
- Upgrading to 5.0.0 may introduce new lint warnings related to JavaScript interop and unnecessary library name usage.
- Code that previously failed the removed lints (
prefer_const_*andavoid_null_checks_in_equality_operators) will no longer be flagged. - Projects must now use newer Flutter and Dart SDKs (at least Flutter 3.24 / Dart 3.5)[1][2][4].
Upgrading will keep your project aligned with the latest best practices and Dart ecosystem trends, and may lead to cleaner, more maintainable codebases[4].

Check for potential issues with package_info_plus upgrade
The package_info_plus dependency has been upgraded from ^5.0.1 to ^8.3.0, which is a significant version jump. Verify that this update is compatible with your app's requirements.
🌐 Web query:
Are there any breaking changes between package_info_plus v5.0.1 and v8.3.0?
💡 Result:
Breaking Changes Between package_info_plus v5.0.1 and v8.3.0
Overview:
Yes, there are breaking changes between package_info_plus v5.0.1 and v8.3.0. The most notable comes in the major release jump to v7.0.0 and subsequent versions.
Major Breaking Change in v7.0.0:
- The Android implementation for the
buildSignaturevalue switched from using its previous hashing method to SHA-256 for improved security."BREAKING FEAT(package_info_plus): Switch to SHA-256 for buildSignature on Android (#2835)"[1].
v5.0.1 Breaking Changes:
- v5.0.1 itself introduced breaking changes related to handling the
versionJsonUrlon web, now allowing for no page extension:"BREAKING FIX(package_info_plus): Allow no page extension in versionJsonUrl on web (#2381)"[3].
- This requires you to adjust your web setup if you had previously relied on an explicit
.jsonextension in URLs.
Other Notable Upgrades Between v5.0.1 → v8.3.0:
- There are other minor and patch releases with additional fixes, features, and internal improvements, but the main breaking change of note is the SHA-256 switch for Android.
- There is no mention in the changelogs of breaking API changes to the core
PackageInfoAPI (such as constructor signatures, returned fields, or general usage) for end-users between these versions[1][3][8]. Most common usage patterns (fetching version, build number, etc.) remain stable.
Upgrade Considerations:
- Android: If your logic depends on the
buildSignaturevalue, expect it to be different due to SHA-256. - Web: Ensure your Flutter web deployment does not rely on the
.jsonextension forversionJsonUrl; update your deployment/server settings if needed. - General: Always clean and rebuild Xcode projects when upgrading, particularly for iOS apps, as incorrect version info may be cached in the build folder[8].
Summary Table of Key Breaking Changes
| Version | Breaking Change Description |
|---|---|
| 5.0.1 | versionJsonUrl can omit .json extension on web[3] |
| 7.0.0 | buildSignature uses SHA-256 on Android[1] |
If you rely on either buildSignature for Android or serve web builds with a specific versionJsonUrl file extension, carefully review your implementation when upgrading between these versions.
Further Recommendations:
- Review the full changelog for
package_info_plusfor all detailed updates between your installed version and the latest[1]. - Test each platform you support (Android, iOS, Web) after upgrading to catch any behavioral nuances, especially around version/build info retrieval and signature computation.

Review Breaking Changes in package_info_plus Upgrade
The jump from ^5.0.1 to ^8.3.0 introduces a couple of breaking changes you should verify:
- Android (v7.0.0):
buildSignaturenow uses SHA-256 instead of the previous hashing method. If your app logic depends on this value, update or re-test accordingly. - Web (v5.0.1):
versionJsonUrlno longer requires a.jsonextension. Ensure your server or deployment doesn’t rely on a fixed.jsonsuffix.
All other core PackageInfo APIs (version, build number, etc.) remain unchanged. Please review your implementation, adjust any dependent logic, and test each platform (Android, iOS, Web) after upgrading.
🤖 Prompt for AI Agents (early access)
In packages/flutter/pubspec.yaml at line 43, the package_info_plus dependency was upgraded from ^5.0.1 to ^8.3.0, which includes breaking changes. Review your app code for any usage of buildSignature on Android and update or retest it due to the switch to SHA-256 hashing in v7.0.0. Also, verify your web deployment does not rely on a .json extension in versionJsonUrl, adjusting server or deployment settings if necessary. Finally, test all platforms thoroughly to ensure compatibility with the new package version.

💡 Result:
Breaking Changes in web_socket_channel v3.0.0
The 3.0.0 release of the Dart web_socket_channel package introduced several breaking changes that impact how developers interact with the API. The main breaking changes are as follows:
-
Removal of
WebSocketChannelConstructor
The direct constructor forWebSocketChannelhas been removed. Developers can no longer instantiate the channel usingWebSocketChannel()and must now use provided factory methods, such asWebSocketChannel.connect, to create channel instances[1][6]. -
WebSocketChannelIs Now an Abstract Interface
TheWebSocketChannelclass has been converted into an abstract interface. This means you cannot instantiate it directly and must instead work with implementations provided by the package, such as viaWebSocketChannel.connect[1][6]. -
Change in Exception Thrown by
IOWebSocketChannel.ready
Thereadyproperty onIOWebSocketChannelpreviously threw aWebSocketExceptionon error. In v3.0.0, this now throws aWebSocketChannelException, requiring consumers to update their exception handling logic when awaiting the connection's readiness[1][6]. -
Adapter Around
package:web_socketfor Web Implementation
An adapter for thepackage:web_socketpackage is now the default implementation for web platform connections made viaWebSocketChannel.connect. This may affect the underlying behavior or compatibility for web-based applications[1][6].
Summary Table
| Breaking Change | Details |
|---|---|
| Constructor removal | No direct WebSocketChannel() instantiation; use factory constructors instead |
| Abstract interface | WebSocketChannel is now abstract; use specific implementations |
Exception change in ready |
Throws WebSocketChannelException (previously WebSocketException) |
| Default web adapter | Uses package:web_socket adapter for web via WebSocketChannel.connect |
Developers upgrading to v3.0.0 should adjust their code to accommodate these changes[1][6].

Validate Breaking Changes for web_socket_channel v3.0.0
We’ve bumped web_socket_channel from ^2.4.3 to ^3.0.3, which includes these breaking changes:
- Removal of the direct
WebSocketChannel()constructor – you must now useWebSocketChannel.connect(...). WebSocketChannelis now an abstract interface.IOWebSocketChannel.readythrowsWebSocketChannelException(instead ofWebSocketException).- Default web implementation now uses the
package:web_socketadapter.
Please audit the Dart code for:
- Any instantiation of
WebSocketChannel()(replace withconnect). - Direct uses of
IOWebSocketChanneland calls to itsreadyproperty (update exception handling). - Web‐platform socket code relying on the old adapter.
Make the necessary updates or confirm that your code paths already comply with the new API.

In packages/dart/pubspec.yaml at line 27, the web_socket_channel dependency has been upgraded from ^2.4.3 to ^3.0.3, which introduces breaking changes. Audit all Dart code that uses web_socket_channel for direct instantiation of WebSocketChannel() and replace these with WebSocketChannel.connect(...) factory methods. Also, update any exception handling around IOWebSocketChannel.ready to catch WebSocketChannelException instead of WebSocketException. Verify web platform socket code to ensure compatibility with the new package:web_socket adapter. Make these code adjustments to align with the new major version API.

🛠️ Refactor suggestion
Enhance the ParseAggregate example with error handling and documentation
The example demonstrates the new aggregation query feature, but could be improved with error handling and better documentation.
Consider adding error handling and more descriptive output:
- final res = await ParseAggregate('DietPlan', pipeline: {
- r'$match': {'Name': 'Ketogenic'}
- }).execute();
-
- print(res);
+ // Execute an aggregate query to filter DietPlan objects
+ final aggregateResult = await ParseAggregate('DietPlan', pipeline: {
+ r'$match': {'Name': 'Ketogenic'}
+ }).execute();
+
+ if (aggregateResult.success) {
+ print("Aggregate query results:");
+ print(aggregateResult.results);
+ } else {
+ print("Aggregate query failed: ${aggregateResult.error?.message}");
+ }🤖 Prompt for AI Agents (early access)
In packages/dart/example/main.dart around lines 26 to 30, the ParseAggregate example lacks error handling and sufficient documentation. Add try-catch blocks around the await call to handle potential exceptions gracefully. Include comments explaining the purpose of the aggregation query and the expected output. Also, enhance the print statement to provide more descriptive output for easier understanding of the results.

Add documentation and consider using Dart's Uri class instead.
This class lacks documentation explaining its purpose and usage. Additionally, it appears to duplicate functionality that's already available in Dart's Uri class.
- Add class-level and field-level documentation
- Add a space after the class name declaration:
class UrlReplace { - Consider whether this utility class is necessary or if Dart's
Uriclass could be used directly
-class UrlReplace{

In packages/dart/lib/src/utils/url_replace.dart lines 1 to 24, add clear class-level documentation explaining the purpose of UrlReplace and field-level comments describing each property. Insert a space after the class name declaration to follow Dart style conventions (change `class UrlReplace{` to `class UrlReplace {`). Finally, review the code to determine if this class is redundant given Dart's built-in Uri class and consider refactoring to use Uri directly if possible.

Remove debug print statement and improve pipeline parameter handling.
The execute() method contains a debug print statement and has some issues with variable naming and error handling.
Make the following improvements:

+ /// Throws an [ArgumentError] if the pipeline is empty.
+ /// Returns a [ParseResponse] containing the query results.

In packages/dart/lib/src/network/parse_aggregate.dart around lines 13 to 33, remove the debug print statement that outputs the result data. Rename the local variable _pipeline to a more descriptive name like queryParameters. Improve error handling by ensuring the pipeline parameter is properly validated and encoded before adding it to the query parameters. Make sure the pipeline is encoded as a JSON array and passed correctly in the request URI.
Pull Request
Add Aggregate Query Support to Parse Flutter SDK
Issue
#664
Closes: FILL_THIS_OUT
Approach
This pull request introduces support for aggregate queries in the Parse Flutter SDK by implementing the ParseAggregate class. This enhancement allows developers to perform complex data aggregations directly within their Flutter applications, leveraging the Parse Server's /aggregate endpoint.
Key Features:
ParseAggregate Class: A new class that facilitates the construction and execution of aggregation pipelines.
Pipeline Validation: Ensures that the provided aggregation pipeline is not empty, throwing an ArgumentError if validation fails.
Seamless Integration: Utilizes existing ParseHTTPClient and handleResponse methods for consistent request handling and response parsing.
Debug Support: Optional debug logging to assist developers during development and troubleshooting.
Parse Community
Usage Example:
Notes:
This implementation aligns with the Parse REST API's aggregate query specifications.
Comprehensive documentation and unit tests have been included to ensure reliability and ease of use.
