Results topic

What an observer reports: a sealed QueryResult (QueryPending, QuerySuccess or QueryError) with the fetch state (isFetching, isStale, failureCount, ...) on every variant. Switch over it; the data needs no !.

Classes

QueryError<TData>

The last fetch failed after its retries, with error.

QueryPending<TData>

The query has nothing to show: no data and no error.

QueryResult<TData>

The result of observing one query: what it holds, and what it is doing.

QuerySuccess<TData>

The query holds data — fetched, seeded, written by hand, or a placeholder — in data.

Typedefs

QueryRefetch<TData> = Future<QueryResult<TData>> Function({bool cancelRefetch})

Refetches the query behind a result.
