Some checks failed
CI / Windows build (push) Has been cancelled
Add a text-annotation tool to the PDF editor. With the text tool a
pen-tap, or a mouse double-click, drops a text box at that normalized
page point and focuses a real Flutter TextField — so the OS IME and the
Windows-Ink handwriting panel feed it (device-validated). Tapping an
existing box re-opens it; clearing it deletes it.
- SidecarText {nx, ny, text, fontSize (page-relative), color} per page,
glued under zoom; stored in the sidecar `texts` field (back-compat
missing -> none), saved via scheduleTextsSave and loaded on open.
- Rendered in pageOverlaysBuilder at the scaled position.
PDF editor only for now (note text later). analyze clean, 397 tests.

// lib/storage/badnote_sidecar.dart

//
|
||
// The on-disk sidecar model: all annotations for one source file, serialized as
|
||
// `<file>.badnote.json` next to the file ("跟着文件走"). This is Phase 1 of the
|
||
// file-based storage plan (docs/plans/2026-06-24-file-based-storage.md §A) — a
|
||
// pure model with NO runtime wiring yet.
|
||
//
|
||
// Design rule: REUSE the existing JSON shapes verbatim; do not invent a parallel
|
||
// stroke format. Specifically:
|
||
// * per-page ink → List<EditorStroke> (lib/editor/engine/stroke_model.dart;
|
||
// byte-for-byte the `ink.stroke_json` column today)
|
||
// * scratchpad ink → List<InkStroke> (lib/models/ink_stroke.dart; the exact
|
||
// format scratchpads already persist, absolute world px)
|
||
// * scratch anchors → ScratchLink (lib/models/scratch_link.dart)
|
||
// * bookmarks → Bookmark (lib/models/bookmark.dart)
|
||
//
|
||
// Only the *containers* and the (previously in-memory-only) highlight rect are
|
||
// new here. Unknown JSON fields are ignored on read so the schema is
|
||
// forward-compatible (e.g. a future `brush` field — see §A.5 brush TODO).
