Interface INavigationRestoreStore

Namespace

Nalu

Assembly

Nalu.Maui.Navigation.dll

Persists the navigation-state snapshot. The default store is a JSON file in the app cache directory; replace in DI for custom locations or formats.

public interface INavigationRestoreStore

Methods

ReadAndDelete()

Reads the persisted snapshot and DELETES it in the same operation (crash-loop containment: a replay that crashes the app yields a clean next boot). Called once during startup — must be synchronous and fast. Returns null when no snapshot exists (or reading fails — restore is fail-open).

string? ReadAndDelete()

Returns

string

WriteAsync(string, CancellationToken)

Persists a snapshot, replacing any previous one. Called debounced in the background; exceptions are swallowed by the caller (capture must never affect navigation).

Task WriteAsync(string snapshot, CancellationToken cancellationToken)

Parameters

snapshot string

cancellationToken CancellationToken

Returns

Task
