timeline_v5 library

Command palette, board, matrix, focus, scenario and recurrence APIs (version 5.x).

Builds on top of the V4 foundation and adds query, recurrence, and new views.

Import this if you want to use only the V5 API (includes V4):

import 'package:neon_timeline_flutter/timeline_v5.dart';

Classes

AgendaView<T>

Text-first chronological view with lazy rows and optional day headers.

CalendarDayView<T>

Modern absolute-positioned day canvas with overlap columns and a static grid layer. It creates no ticker and performs no work while idle.

DependencyTimelineView<T>

Interactive dependency map with deterministic topological layers.

ListTimelineDataSource<T>

Mutable in-memory source suitable for local state and examples.

PlannerView<T>

Dense schedule preset for task, shift, and resource planning surfaces.

PresentationTimelineView<T>

Read-only timeline preset for reports, screenshots, and presentations.

ResourceTimelineView<T>

Multi-resource planning board for people, rooms, machines, and teams.

RoadmapView<T>

Horizontal milestone-oriented timeline with stable lazy rendering.

ScheduleView<T>

Planner-grade schedule using neutral entries, themes, and interaction policy.

TimelineAnalytics

Aggregate planning metrics with an O(n log n) concurrency sweep.

TimelineAnalyticsSnapshot<T>

TimelineBackdrop

Theme-aware background surface for full-screen timeline products.

TimelineBoardView<T>

TimelineCapacityConflict<T>

TimelineCapacityEngine

Resource overbooking sweep. Adjacent ranges do not conflict.

TimelineCard

Modern, neutral task card with no permanent ticker or storage behavior.

TimelineCommand

Reversible application command used by direct manipulation and shortcuts.

TimelineCommandHistory

Serial command history with guarded undo and redo.

TimelineCommandPalette

TimelineConflictGroup<T>

A connected overlap cluster produced in linear time after sorting.

TimelineController<T>

Host-owned controller for selection, zoom, focus, and visible-range state.

TimelineDataSource<T>

Backend-independent source contract for future paged and live adapters.

TimelineDateRange

TimelineDayEntryDetails<T>

TimelineDayLayoutEngine

Deterministic overlap-column assignment for day and resource canvases.

TimelineDayLayoutItem<T>

Positioned entry produced by TimelineDayLayoutEngine.

TimelineDependency

TimelineDependencyAnalysis<T>

TimelineDependencyEngine

Dependency analysis with O(V + E) graph traversal after ID indexing.

TimelineDependencyIssue

TimelineDependencyNodeDetails<T>

TimelineDiagnostics

Opt-in snapshot delivery. It creates no timer and no continuous work.

TimelineDiagnosticsSnapshot

TimelineEntry<T>

Application-owned value adapted to the neutral 4.x timeline engine.

TimelineEntryDetails<T>

Normalized builder context shared by the new view widgets.

TimelineFocusView<T>

TimelineGap<T>

TimelineInteractionConfig

Interaction policy shared by schedule and planner views.

TimelineLayoutConfig

Generic orientation and layout settings shared by view widgets.

TimelineLocalization

Injects package-owned fallback strings below a subtree.

TimelineLocalizationData

Host-supplied strings used by package-owned neutral UI fallbacks.

TimelineMatrixView<T>

TimelineMetricCard

TimelineMotionConfig

Motion policy. It never changes layout or data semantics.

TimelineNormalizedEntry<T>

TimelineOverviewStrip<T>

TimelinePaletteCommand

TimelinePanel

Reusable modern panel. Backdrop blur requires both a glass-capable theme and explicit per-panel opt-in, so dense dashboards remain cheap by default.

TimelinePerformanceConfig

Neutral 4.x performance policy with a compatibility bridge to 3.x painters.

TimelinePlugin

Versioned extension point. The registry is host-owned, never global.

TimelinePluginRegistry

TimelineQuery<T>

TimelineQueryResult<T>

TimelineRecurrenceRule

TimelineRenderPlan<T>

Immutable, deterministic plan shared by the 4.x view and diagnostics layer.

TimelineRenderPlanBuilder<T>

Stateful cache boundary for widgets that consume a render plan.

TimelineRenderPlanCache<T>

Reusable render-plan cache with explicit revision-based invalidation.

TimelineResource

A person, room, machine, team, or other schedulable resource.

TimelineResourceCapacity

TimelineResourceEntryDetails<T>

TimelineScenario<T>

TimelineScenarioChange<T>

TimelineScenarioCompareView<T>

TimelineScenarioComparison<T>

TimelineScenarioEngine

TimelineSectionHeader

TimelineStatusBadge

TimelineTemporalHit<T>

TimelineTemporalIndex<T>

Immutable temporal index for fast range queries.

TimelineTheme

TimelineThemeData

Complete design-token set for the neutral 4.x UI layer.

TimelineView<T>

Neutral, lazy timeline view backed by the proven 3.x renderer.

TimelineWorkspace

Responsive product shell for advanced planner and timeline applications.

TimelineWorkspaceDestination

Enums

Conflict categories emitted by TimelineRenderPlan.

TimelineDependencyIssueType

TimelineDependencyType

TimelineLayout

Placement strategy for the rail and timeline content.

TimelinePerformanceProfile

TimelineScenarioChangeKind

TimelineSelectionMode

Selection behavior for interactive views.

TimelineStatus

Stable lifecycle state shared by every 4.x timeline view.

TimelineTimeSemantics

Date normalization policy used by the core engine.

TimelineViewKind

Product-level view modes supported by the timeline platform API.

TimelineVisualStyle

Built-in visual languages. Custom themes remain first-class.
