ComparedItem class
One thing compared, on every channel that had something to say.
Channels rather than "a picture plus some extras." Pixels have a threshold, texts are exact, and the events channel that is coming will need field masks for tokens and timestamps. Making each channel own its own rules now is what lets a new one land later without reopening the kernel — and what lets a reader who cannot see pixels, which is every agent, read the same comparison a human is looking at.

Properties
-
channelsFired
→ List<
String> -
Which channels had something to say about this item.
no setter
-
deltas
→ List<
ChannelDelta> -
Every difference this item found, on every channel, as one flat list.
no setter
- events → EventChannel?
-
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- id → String
-
What was compared: an entry id, or a step's path through its flow — made
unique within it, see
StepIds.final - label → String?
-
How it names itself on screen — a step's
tap #pay, an entry's name.final - note → String?
-
Why it is in the state it is, when the state alone does not say: which
file made it worth rendering, or which side failed to render.
final
- package → String?
-
Which package declared it, worktree-relative —
app,packages/gallery. Null on a row from a comparison written before a comparison could span several, and on a step, which takes its package from the scenario holding it.final - pixels → PixelChannel?
-
final
- retargeted → ({String base, String head})?
-
What the step aimed at on each side, when the test names its target
another way than it did — a renamed key, a finder by key where there was
one by index. Null for every step aimed the way it was, and for an entry.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- shots → ({String base, String head})?
-
Where the two frames are filed, as
ShotCachekeys.final - state → ComparedState
-
final
- texts → TextChannel?
-
final
- tree → TreeChannel?
-

inPackage(
String package, {required bool qualify}) → ComparedItem -
The same row, addressed inside
package. -

Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

-
toJson(
) → Map< String, Object?> -

Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
fromJson(
Map< String, Object?> json) → ComparedItem -
A row read back off
index.json— what an exported page draws from. -
