History HistoryLegacyCard

HistoryLegacyCard

A summary from before chapters and episodes: the title (when there is one), the summary, the start and end times and the message count. Nothing opens in it.

import 'package:agent_kit/agent_kit.dart';

Demo

Legacy: the card of the checkpoint summary from before chapters. The gallery builds HistoryLegacy checkpoint with no title, so the card shows "Chapter · Oct 24 – 25 · closed", the summary and "142 messages". The orange left edge is outlineColor(context, colorIndex).

Parameters

Parameter	Type	Notes
legacy	HistoryLegacy (required)	Read: title (shown only when non-null and non-empty), summary, startedAt, endedAt, messageCount, colorIndex.

Theme roles

colors.bgElevated (card background), colors.border (card border), colors.textTertiary (header line), colors.textPrimary (title and summary), colors.textSecondary (message count), typeScale.uiSmall, typeScale.body, typeScale.h3 (title, through tsDisplay), Radii.lg (corners). The edge colour comes from outlineColor(context, colorIndex).

Size classes

Does not read the size class. The card takes the width of its parent.

Accessibility

• No Semantics node and no tooltip. The text is read as written.
• No interaction. Nothing opens in the card.
• No reduced-motion handling in this file.

Gallery and tests

• Gallery scene: History (GalleryScene.history, HistoryScene). The legacy entry is the first item of the scene's chapter list.
• Golden: apps/gallery/test/component_shots_test.dart writes history_legacy_card (index 0), _light.png and _dark.png. The whole scene is in h_history_1600_<theme>.png and h_history_390_<theme>.png.
• Other tests, packages/agent_kit/test/history/history_test.dart: "a legacy card shows title, summary, times and count".
