MissionMessage class - mission library

Constructors

MissionMessage({required String missionId, required List<MissionStep> steps, String? goal, bool continueOnFailure = false, int? invalidStepIndex, int? declaredStepCount}): const
MissionMessage.fromJson(Map<String, dynamic> json): Strict parse: throws on a missing mission_id or any malformed step.
factory

continueOnFailure → bool: Tour semantics (Android MissionMessage.continueOnFailure): a failed step is reported as a non-terminal step_failed and SKIPPED instead of aborting the mission. Parsed strictly — only a JSON true turns it on.
final
declaredStepCount → int: How many steps the frame declared (parsed or not) — steps_total on the terminal frame of a malformed mission.
no setter
goal → String?: Optional human-readable goal.
final
hashCode → int: The hash code for this object.
no setterinherited
invalidStepIndex → int?: Index of the first step that could not be parsed, or null for a well-formed mission. A malformed mission is still dispatched so the runner can answer failed failure_reason=invalid_mission instead of silently dropping the frame.
final
isValid → bool: no setter
missionId → String: Backend-assigned ID.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
steps → List<MissionStep>: final
type → String: no setter

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>
toString() → String: A string representation of this object.

tryParse(Map<String, dynamic> json) → MissionMessage?: Defensive parse. Null ONLY when mission_id is missing / not a non-empty string (nothing can be reported back for such a frame). A malformed step yields a mission with invalidStepIndex set.
