StatCardGrid class

A responsive "bento grid" layout for dashboard stat cards — an optional full-width hero card up top, with the rest flowing into a fixed-column grid beneath it.

This is the layout half of the dashboard kit: GaugeRingCard, GaugeBarCard, and the presets in stat_card_presets.dart provide the cards, and StatCardGrid arranges them the way a car's in-cabin "booking" or status dashboard typically does — one hero stat (usually speed) commanding attention, with secondary stats (battery, range, climate, tyre pressure, ...) tiled below.

The column count adapts to the available width, so the same grid reads as a single column on a phone-sized panel and multiple columns on a tablet or in-car display.

StatCardGrid(
  hero: SpeedStatCard(controller: speedCtrl),
  children: [
    BatteryStatCard(controller: batteryCtrl),
    RangeStatCard(controller: rangeCtrl),
    ClimateStatCard(controller: climateCtrl),
    TirePressureStatCard(controller: tireCtrl),
  ],
)

Properties

children → List<Widget>
The secondary stat cards, tiled into a responsive grid beneath hero.
final
hashCode → int
The hash code for this object.
no setterinherited
hero → Widget?
An optional full-width card shown above the grid — typically the single most important stat (e.g. current speed).
final
heroHeight → double
Fixed height reserved for hero, regardless of the grid's column count.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
minTileWidth → double
The narrowest a grid tile is allowed to get before another column is dropped. Smaller values pack more columns into the same width.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
spacing → double
Gap between cards, both within the grid and between hero and the grid.
final
tileAspectRatio → double
Width-to-height ratio of each grid tile.
final
