How to get data type from onMutate function in useMutation
I'm doing optimistic updates using the technique which is documented here https://tanstack.com/query/latest/docs/framework/react/guides/optimistic-updates .

datadata parameter in the onMutate function. I've tried using
type MutateData = Parameters<typeof api.task.createTask.useMutation>[0] type MutateData = Parameters<typeof api.task.createTask.useMutation>[0] . The problem is that I can't then access the ['onMutate'] because it doesn't exist on there. Does anyone know how to get this?React Query provides two ways to optimistically update your UI before a mutation has completed. You can either use the onMutate option to update your cache directly, or leverage the returned variables to update your UI from the useMutation result.
