[FEATURE]: Clean Up Temporary Audio Files After Transcription #19
Description
Feature and its Use Cases
Problem
The application records audio consultations and stores them temporarily on the device using path_provider and record. A new audio file is created for every recording session.
Example from lib/main.dart:
final directory = await getTemporaryDirectory();
_recordingPath =
'${directory.path}/recording_${DateTime.now().millisecondsSinceEpoch}.m4a';This file is later used for transcription:
final file = File(_recordingPath);
if (!await file.exists()) {
return;
}
final bytes = await file.readAsBytes();
final response = await http.post(...);However, after transcription is completed, the recorded audio file is never deleted.
A search across the repository shows no usage of:
File.delete()
deleteSync()
As a result, each consultation leaves behind a temporary audio file.
Over time, this can lead to:
- accumulation of unused audio files
- unnecessary device storage usage
- degraded app performance due to large temporary storage
Proposed Solution
Delete the temporary audio file after the transcription process finishes.
Example implementation:
try {
final file = File(_recordingPath);
if (await file.exists()) {
await file.delete();
}
} catch (_) {
// ignore cleanup failures
}This cleanup should occur after transcription completes, regardless of whether the API request succeeds or fails.
Suggested location:
- at the end of
_transcribeAudio()inlib/main.dart - also in any early-return paths where a file may have been created
Expected Outcome
- Temporary audio files are removed after each transcription
- Device storage remains clean
- Prevents long-term accumulation of unused files
