Complete removal of recognition history features:
1. State Variables Removed:
- _recognitionHistory list variable
- _realtimeResults list variable
- All history-related state management
2. Methods Updated:
- _clearHistory() renamed to _clearContent()
- Simplified to only clear current text and base text
- Removed history list operations
3. UI Components Removed:
- _buildHistoryCard() method completely removed
- History card from main layout removed
- History-related ListView and ListTile widgets removed
4. Callback Logic Simplified:
- onListeningStatusChanged callback cleaned up
- Removed history insertion logic when recording stops
- Removed _realtimeResults.clear() operations
- Simplified state management to focus only on current text
5. App Bar Updated:
- Clear button tooltip changed from '清除历史' to '清除内容'
- Button now calls _clearContent() instead of _clearHistory()
The app now focuses purely on real-time speech recognition with
editable text input, without maintaining any recognition history.
This simplifies the codebase and improves performance by removing
unnecessary data storage and UI rendering.
Major SDK simplification by removing redundant final result processing:
1. YxAsrService changes:
- Remove final result retrieval in stopListening()
- Remove finalResult parameter from _sendResult()
- Simplify stop logic to only reset stream state
- Eliminate duplicate API calls that provided no additional value
2. SpeechRecognitionResult model changes:
- Remove finalResult property and related logic
- Update constructor, factory methods, toString, equals, hashCode
- Remove finalResult from toMap/fromMap serialization
- Simplify the model to focus on actual recognition data
3. Benefits:
- Cleaner, more maintainable codebase
- Reduced complexity and potential bugs
- Better performance (no redundant API calls)
- Simpler API for developers to use
- Real-time text appending works seamlessly without artificial distinctions
The analysis showed that 'final results' were identical to the last real-time result,
making the distinction unnecessary. Now all results are treated uniformly as
real-time updates, providing a smoother and more intuitive user experience.
1. Add _baseText variable to track text before recording starts
- Preserves existing text when starting new recording session
- Provides foundation for real-time appending
2. Update real-time result processing logic
- Real-time results now immediately update the text field
- Combine base text + current recognition text
- Move cursor to end for better UX
- Add intelligent spacing between segments
3. Improve final result handling
- Final results update base text for next recording
- Clean state management between recording sessions
4. Update recording status change logic
- Capture base text when recording starts
- Maintain proper state transitions
Now users can see their speech being converted to text in real-time directly in the input field, providing immediate visual feedback during speech recognition.
1. Update UI to show actual _currentText instead of fixed 'realtime recognizing...' text
- Use Flexible widget to handle text overflow
- Show actual recognition text when available
- Fallback to 'realtime recognizing...' when text is empty
2. Fix final result processing logic
- Don't update _currentText when processing final results
- Final results only append to text field, don't interfere with real-time display
3. Improve listening status management
- Clear _currentText when recording stops
- Ensure clean state transitions between recording sessions
This fixes the issue where users could only see final results without real-time feedback.
1. Add finalResult property to SpeechRecognitionResult class
- Distinguish between real-time and final recognition results
- Update factory methods, toString, equals, and hashCode
- Update toMap and fromMap methods
2. Update YxAsrService to support finalResult flag
- Add finalResult parameter to _sendResult method
- Mark final results with finalResult: true
- Keep real-time results as finalResult: false (default)
3. Remove unused methods to clean up codebase
- Remove unused _toggleRecording method
- Remove unused _updateTextController method
- Clean up orphaned comments
These fixes resolve linter errors and ensure proper text appending functionality.
- Change from replacing current text to appending final results
- Distinguish between real-time results (display only) and final results (append to text)
- Add proper spacing between appended text segments
- Maintain history of individual recognition segments
- Clear current text when starting new recording session
