ImpactConfig class

Crash & fall detection.

When enableCrashDetection is true, a corroborated high-g impact while moving raises a potential_crash (with a confirmWindowMs cancel countdown) that auto-confirms to crash unless cancelled — delivered via Tracelet.onImpact. enableFallDetection adds best-effort personal-fall detection (more false positives; default off).

Default: disabled. Tracelet provides the trigger + cancel window; it never places emergency calls.

Constructors

ImpactConfig({bool enableCrashDetection = false, bool enableFallDetection = false, double crashGThreshold = 2.0, double crashMinSpeedKmh = 25.0, double fallGThreshold = 2.5, int confirmWindowMs = 15000, double minImpactConfidence = 0.6})

Creates a new ImpactConfig.

const

ImpactConfig.fromMap(Map<String, Object?> map)

Creates an ImpactConfig from a map.

Properties

confirmWindowMs → int

Countdown (ms) before a candidate auto-confirms. Default 15000.

final

crashGThreshold → double

Impact magnitude (g) for a crash candidate. Default 2.0 (lowered from 3.0 after a field-data study found 3.0 g missed ~half of real crashes; the cancel-countdown offsets the extra false alarms).

final

crashMinSpeedKmh → double

Pre-impact speed (km/h) required to corroborate a crash. Default 25.

final

enableCrashDetection → bool

Master switch for vehicle crash detection.

final

enableFallDetection → bool

Personal fall detection (best-effort; default false).

final

fallGThreshold → double

Impact magnitude (g) for a fall candidate. Default 2.5.

final

hashCode → int

The hash code for this object.

no setter, override

minImpactConfidence → double

Suppress candidates below this confidence. Default 0.6.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toMap() → Map<String, Object?>

Serializes to a map.

toString() → String

A string representation of this object.

inherited

toTlConfig() → TlImpactConfig

Converts to Pigeon TlImpactConfig.

Operators

operator ==(Object other) → bool

The equality operator.
