MutationFn<TData, TVariables> typedef

MutationFn<TData, TVariables> = FutureOr<TData> Function(TVariables variables)

The function a mutation runs: it performs the write for variables and returns (or completes with) the server's answer, which becomes the mutation's data. Throwing, or completing with an error, fails the attempt. Set through MutationOptions.mutationFn.

Implementation

typedef MutationFn<TData, TVariables> = FutureOr<TData> Function(
    TVariables variables);
