AnalyticsScalarCard class

A self-contained card that runs a single scalar query and shows the result as a big number inside CardChrome.

A convenience for the common "one KPI per card" case; for spec-driven dashboards use HandDrawnAnalyticsCard.

Constructors

AnalyticsScalarCard({required SingleQuerySpec query, String? title, WidgetQueryRunner? runner, BridgeFormatters? formatters, DateRangeMode dateRangeMode = const NoDateRange(), (DateTime, DateTime)? pageRange, DateTime? earliestDataDate, DateTime? today, DateTime? asOf, VoidCallback? onEdit, TextStyle? valueStyle, Color? color, Key? key})
const

Properties

asOf DateTime?
Reference date for StreakMeasure evaluation. When null, the runner resolves it to the wall clock at fetch time, so leaving it null is the stable default — the card refetches only when an explicit value changes.
final
color Color?
final
dateRangeMode → DateRangeMode
How the date range is applied. A relative preset resolves against today (or the wall clock when today is null) at fetch time and re-resolves when the card next refetches — not spontaneously at a day boundary.
final
earliestDataDate DateTime?
final
formatters BridgeFormatters?
final
hashCode int
The hash code for this object.

key Key?
Controls how one widget replaces another widget in the tree.
