The app half of #276. A placed image may name the picture it shows (assetId), so a copy of an image can show its original's picture without copying or uploading anything. This PR teaches the app to read and keep that field everywhere it finds a picture. It doesn't create such images yet; the copy PRs (#272, #274/#275) do.

What changes

  • PlacedImage.assetId is an optional field: Hive field 11, and JSON assetId written only when set. pictureId (assetId ?? id) is the id the picture is stored, uploaded and found under.
    • Every image, .ica file and backup made so far has no assetId, so it reads and writes exactly as before. Its cloud payload is unchanged too, so no rows are rewritten.
    • Old builds ignore Hive field 11, so going back to an earlier version still reads the library.
  • Picture lookups use pictureId:
    • drawing an image, and its page transition;
    • screenshots and video export;
    • the upload queue (what to upload, and which queued edit relies on an upload);
    • preparing a cloud strategy for export;
    • local-to-cloud migration, where a renamed image keeps its picture;
    • the old embedded-bytes serializer.
  • Opening a local strategy deletes picture files nothing uses, and now keeps every picture any image shows. Before, deleting an image whose copy still showed its picture would have deleted the shared file. A test fails without this fix.
  • Item identity stays the image's own id: undo, transitions, sync rows, resize and delete. ImageWidget takes the picture id separately, so its hero tag stays unique when two images share a picture.

Ground truth

In a web build against dev, with the whole stack deployed, I held the image's upload for 20 seconds. Frames: just placed; the copy made by "+" during the hold; the copy after the upload landed. A copy-to-page of the same image looked the same.

Image copied while its upload was held

Tests

  • color_persistence_test:
    • a Hive record from before the field reads with its own picture and writes no assetId;
    • a record with the field keeps it through JSON and copyWith.
  • strategy_integrity_test: an .ica with an image and a copy showing its picture imports, exports the picture once, and re-imports. Opening the strategy after the original is deleted keeps the picture file. That last check fails with the old cleanup.
  • web_media_bytes_upload_test: a copy's picture is uploaded once, under the picture's id.
  • Full suite passes. One queue-batching test failed once under full-suite load and passes alone and with its file.

Library format change, stacked on #276 (which deploys first). You look first.

Summary by CodeRabbit

  • New Features
    • Copied images can now share the same underlying picture while keeping their own placement identity.
    • Shared pictures remain available across collaboration, import and export, local storage, screenshots, and video exports.
    • Collaboration requests now support picture IDs.
  • Bug Fixes
    • Prevented shared pictures from being missed or uploaded more than once during media reconciliation.

A placed image may name the picture it shows (assetId, Hive field 11);
without one, its own id names the picture, as before, so every image,
.ica file and backup made so far reads exactly as it did. pictureId is
the id the picture is stored, uploaded and found under: rendering, the
page transition, screenshots, video export, the upload queue, cloud
export, local-to-cloud migration and the cleanup of unused picture
files all use it. Item identity (undo, transitions, sync rows, hero
tags) stays the image's own id.

Nothing makes such images yet; copies will (see the server half).

📝 Walkthrough

Walkthrough

Placed images now distinguish their placement ID from the picture asset ID through optional assetId and derived pictureId. Cloud requests, media reconciliation, import/export, persistence, rendering, screenshots, and video export use the picture identifier where appropriate. Legacy records fall back to the image ID.

Changes

Shared picture IDs for placed images

Layer / File(s) Summary
Placed-image identity and persistence
lib/const/placed_classes.dart, lib/const/placed_classes.g.dart, lib/hive/hive_adapters.g.*, test/color_persistence_test.dart
PlacedImage adds optional assetId and a pictureId getter that falls back to id. JSON and Hive persistence handle the field. Tests cover legacy records and distinct picture IDs.
Cloud asset references and hydration
lib/collab/*, lib/strategy/strategy_cloud_migration.dart, lib/strategy/strategy_import_export.dart, lib/strategy/strategy_page_source.dart, test/collab/referenced_asset_ids_test.dart, test/strategy_integrity_test.dart
Cloud requests advertise picture ID support. Asset collection, migration, import/export caching, and page hydration resolve image assets through picture IDs. Tests cover request flags and image references through import, export, and reload.
Picture-based upload reconciliation
lib/providers/collab/cloud_media_upload_queue_provider.dart, test/web_media_bytes_upload_test.dart
Media reconciliation checks remote assets, existing jobs, and local bytes by picture ID. Operation references resolve assetId when present. A test covers a copied image referencing pending bytes.
Picture-based media lookup and rendering
lib/providers/image_provider.dart, lib/providers/strategy_provider.dart, lib/screenshot/page_screenshot.dart, lib/services/video_export/video_export_source.dart, lib/widgets/draggable_widgets/image/*, lib/widgets/page_transition_overlay.dart, test/canonical_coordinates_test.dart, test/strategy_image_source_test.dart
Local file paths, cleanup, screenshots, video export, and image widgets use pictureId for image lookup. Widget call sites and test fixtures pass the identifier.

Merge Risk: 🔵 Low · up to 5b239

Deleted images may reappear during migration, and images with an empty asset ID may fail to load or upload. Address these cases before merging, or explicitly accept the bounded risk.

This client keeps PlacedImage.assetId, so it reads snapshots and op
results with it (acceptsPictureIds); older clients get them without.

Normalize empty assetId to null in PlacedImage.

PlacedImage.fromJson and the Hive adapter accept assetId: '', so pictureId becomes empty. Cloud operation matching treats an empty assetId as absent and uses the placement ID instead. Image lookup and upload reconciliation use pictureId directly. This mismatch can make the existing asset or local bytes unavailable and produce ImageFailed or skip the upload.

Suggested fix
   PlacedImage({
     required super.position,
     required super.id,
     required this.aspectRatio,
     required this.scale,
     required this.fileExtension,
     this.sizeVersion,
     this.tagColorValue,
     this.link = '',
-    this.assetId,
-  });
+    String? assetId,
+  }) : assetId = assetId?.isNotEmpty == true ? assetId : null;

Preserve isDeleted when migration renames an image.

If a stored image has a duplicate element ID and isDeleted == true, this branch calls image.copyWith. That clone defaults isDeleted to false. The migration payload then describes the deleted image as active. Preserve the source value when constructing the payload.
