DefaultedQueryObserverOptions<TQueryData, TData> class final Advanced

QueryObserverOptionsBase with every default resolved: DefaultedQueryOptions plus the observer-only options, what a QueryObserver actually runs on.

Only QueryClient produces one, through QueryClient.defaultQueryObserverOptions; an observer resolves the options it is handed on construction and on every setOptions. Value equality tells the observer whether a rebuild changed anything. queryOptions is the part the shared cache entry receives.

Properties

behavior → FetchBehavior<TQueryData>?

QueryOptions.behavior: set for infinite queries, null otherwise.

final, inherited

enabled → Enabled

QueryOptions.enabled, with the default applied.

final, inherited

gcTime → GcTime

QueryOptions.gcTime, with the default applied.

final, inherited

hashCode → int

The hash code for this object.

no setter, override

initialData → InitialData<TQueryData>?

QueryOptions.initialData; there is no default.

final, inherited

initialDataUpdatedAt → DateTime?

QueryOptions.initialDataUpdatedAt; there is no default.

final, inherited

initialDataUpdatedAtCompute → DateTime? Function()?

Computes the seed timestamp only when data is actually seeded. Mutually exclusive with initialDataUpdatedAt; a null result uses now.

final, inherited

meta → Object?

QueryOptions.meta, with the key's registered default applied.

final, inherited

networkMode → NetworkMode

QueryOptions.networkMode, with the default applied.

final, inherited

placeholderData → PlaceholderData<TQueryData>?

QueryObserverOptionsBase.placeholderData; there is no default.

final

queryFn → QueryFn<TQueryData>?

QueryOptions.queryFn, with the key's registered default applied. Still nullable: a query can be built without a function and fails only when it tries to fetch.

final, inherited

queryKey → QueryKey

QueryOptions.queryKey.

final, inherited

queryOptions → DefaultedQueryOptions<TQueryData>

The cache-layer view of these options — the fourteen fields a Query runs on, and none of the observer's own.

late, final

refetchInterval → RefetchInterval

QueryObserverOptionsBase.refetchInterval, with the default applied.

final

refetchIntervalInBackground → bool

QueryObserverOptionsBase.refetchIntervalInBackground, with the default applied.

final

refetchOnMount → RefetchOn

QueryObserverOptionsBase.refetchOnMount, with the default applied.

final

refetchOnReconnect → RefetchOn

QueryObserverOptionsBase.refetchOnReconnect, with the default applied.

final

refetchOnWindowFocus → RefetchOn

QueryObserverOptionsBase.refetchOnWindowFocus, with the default applied.

final

retry → RetryPolicy

QueryOptions.retry, with the default applied.

final, inherited

retryDelay → RetryDelay

QueryOptions.retryDelay, with the default applied.

final, inherited

retryOnMount → bool

QueryObserverOptionsBase.retryOnMount, with the default applied.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

select → SelectFn<TQueryData, TData>?

QuerySelectOptions.select, or null for a QueryObserverOptions; there is no default.

final

staleTime → StaleTime

QueryOptions.staleTime, with the default applied.

final, inherited

structuralSharing → StructuralSharing<TQueryData>?

QueryOptions.structuralSharing; null still means replaceEqualDeep.

final, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

Field-by-field equality, functions compared by identity. It is what tells a rebuild that nothing actually changed.
