AppSnapshot class

Represents a serializable snapshot of the app's meaningful state.

Used by SnapshotManager to persist state for crash recovery. Every field is independently validated during deserialization — a corrupt field becomes its empty default, never crashes the recovery process.

Constructors

AppSnapshot({required String snapshotId, required List<String> routeStack, required Map<String, double> scrollPositions, required Map<String, dynamic> formInputs, required Map<String, dynamic> customState, required DateTime timestamp})

const

AppSnapshot.fromJsonSafe(Map<String, dynamic> json)

Safe deserialization: every field is validated independently. A corrupt field falls back to its default — never throws.
