A blank note can show a page-background template painted behind the
ink, picked from the toolbar and persisted per notebook.
- NoteBackground: blank / dots / ruled / grid / cornell, drawn in
page space (scales with zoom), subtle grey. Cornell = left margin +
bottom summary rule over a ruled body.
- Stored as the enum name in the notebook sidecar (back-compat:
missing/unknown -> blank), saved/loaded via SidecarRepository so it
restores on reopen.
- Picker added to the note tool palette.
PDF backgrounds skipped (PDFs have their own page content). analyze
clean, 386 tests green.
Phase 6 (final storage phase).
- SidecarRepositoryRegistry tracks every open repo; SidecarFlushObserver
(a WidgetsBindingObserver in main) flushes them all on
inactive/hidden/paused/detached, awaiting each flush — the last
strokes can't be lost on app close, not just on the 800ms timer.
- VaultSearchIndex rebuilds by scanning vault sidecars (the source of
truth) — note titles, OCR text and document names — and search_provider
queries it, so search spans notes + PDFs. Rebuilt on launch / after
import.
The vault file-based storage migration (Phases 0-6) is complete:
annotations travel with the file, picked vault folder, atomic autosave,
one Import-file entry, SQLite migrated to sidecars. analyze clean,
tests green.
Phase 5. On first launch with a valid vault, migrate legacy SQLite
data into vault sidecars so nothing is lost on upgrade.
- SqliteToSidecarMigrator: documents (+ per-page ink, scratch-links
+ scratchpads, bookmarks) -> notebook folder + <file>.badnote.json;
notes (+ strokes) -> notebook.badnote.json. Reuses existing JSON.
- Idempotent (skips already-migrated targets); missing source files
still get their annotations migrated.
- DB relocates to <vault>/.badnote/index.sqlite; the legacy DB is
renamed to .premigration ONLY after a successful pass, so a failed
migration leaves data intact and the run-once flag unset.
- main.dart runs it once, gated on vaultMigrationDone.
Golden migrator tests (seeded legacy DB -> sidecars, idempotent
re-run, legacy preserved). analyze clean, tests green.
Phase 4. Standalone notes move off SQLite into the vault, like the
PDF annotations.
- "Create notebook" makes a vault folder with a notebook.badnote.json
(BadnoteSidecar docType 'notebook' + a title field), opened via
SidecarRepository.
- PenNoteScreen loads/saves its strokes (page 0) + title to that
sidecar instead of the SQLite Note model.
- note_provider lists notes from a vault scan (VaultService.scanNotes
= folders with notebook.badnote.json and no source file); the doc
scan still excludes them. Delete removes the folder.
PDF/slide editors unchanged; pre-existing SQLite notes migrate in
Phase 5. analyze clean, tests green.
Phase 1 of the file-based storage plan. Pure library, no runtime
behavior change yet (editors still use SQLite).
- BadnoteSidecar: per-file annotation document (schema-versioned)
holding per-page ink (EditorStroke JSON), text highlights,
scratch-link anchors (ScratchLink JSON) each with its own
scratchpad (InkStroke world-coord JSON), and bookmarks. Reuses the
existing toJson formats — no parallel stroke format.
- SidecarStore.writeAtomic: temp-file + rename atomic write keeping a
.bak; read() falls back to .bak on a missing/corrupt primary.
Round-trip + atomic-write + .bak-recovery tests. analyze clean,
322 tests green.
