JSON Schema

{
  "exportedAt": "2026-07-12T10:00:00Z",
  "version": 1,
  "projects": [ { "id": 1, "name": "...", "color": -16711936 } ],
  "tags": [ { "id": 1, "name": "backend" } ],
  "entries": [
    {
      "id": 42, "projectId": 1, "startTime": "...", "endTime": "...",
      "durationSeconds": 9000, "note": "...", "tagIds": [1]
    }
  ]
}

JSON export can be used as a full backup and re-imported in a future version.

final file = await _buildExportFile(format);          // write to temp dir
await Share.shareXFiles([XFile(file.path)],           // share_plus
  subject: 'Timetrack Export ${DateFormat.yMd().format(DateTime.now())}');

Always write to getTemporaryDirectory() — never to arbitrary paths.

Export Scope
