描述
Description
Several issues were identified in the TaskServer 3 (CCSync v3) integration of the Flutter application.
These include bugs affecting reliability, missing parsing functionality, and UI improvements to make configuration clearer.
This issue proposes fixes and enhancements to improve stability, error handling, and usability.
Problems Identified
1. Hardcoded Origin URL
File: origin.dart
Problem
The origin parameter is currently hardcoded to:
http://localhost:8080
This prevents the application from connecting to remote or user-configured backend servers.
Proposed Solution
Replace the hardcoded value with a dynamic function:
Future getOrigin()
This function retrieves the backend URL from:
CredentialsStorage.getApiUrl()
2. Invalid ScaffoldMessenger Context
File: complete.dart
Problem
The code attempts to call:
ScaffoldMessenger.of(context as BuildContext)
This may cause runtime crashes when the BuildContext is invalid or disposed.
Proposed Solution
Remove the unsafe UI call and instead:
- Throw exceptions for non-200 HTTP responses
- Allow the caller to handle UI feedback.
3. Excessive Timeout Duration
File: manage_task_champion_creds_controller.dart
Problem
The HTTP timeout is set to:
Duration(seconds: 10000)
(~166 minutes)
This prevents the application from failing quickly when the server is unreachable.
Proposed Solution
Reduce the timeout to:
Duration(seconds: 10)
This improves responsiveness when the TaskServer is unavailable.
4. Missing Annotation Parsing
File: task.dart
Problem
The TaskForC model initializes annotations as an empty list:
annotations = []
This ignores annotation data returned by the server.
Proposed Solution
Update the fromJson method to parse annotations dynamically using:
Annotation.fromJson
5. Mode Selector Visibility
Files
profiles_list.dartprofile_view.dart
Problem
The TW2 / TW3 / TW3C mode selector is buried inside the profile view and lacks visibility.
Users cannot easily determine the currently active mode.
Proposed Solution
Add a getModeLabel callback to display the currently selected mode as a subtitle in the Change Mode option.
Acceptance Criteria
- Origin URL is dynamically retrieved
- ScaffoldMessenger crash is removed
- Timeout duration is reduced
- Task annotations are parsed correctly
- Current mode is visible in the profile UI
Tests
Unit tests should verify:
- Annotation parsing in
TaskForC.fromJson - Exception handling in
completeTask - Timeout configuration regression
