zonePhasesKey constant
Symbol
const zonePhasesKey
Key used to register custom phases inside a Dart Zone.
It can be used to query and override the TaskPhases being used in the current Zone.
When registering a List, it must be mutable to allow new custom tasks being created.
Use currentZoneTaskPhases to access the Zone's phases.
Implementation
static const Symbol zonePhasesKey = #zonePhases;
