riverpod_mutations

Description:

riverpod mutations

A simple package to implement mutations for riverpod

Intended to be a stop-gap measure intended to be replaced by official riverpod mutations, once they are implemented.
Intended to be hopefully api-compatible with riverpod mutations once they are implemented.

@riverpod
MutationState<double, String> stringToDouble(StringToDoubleRef ref) {
// user passes in a String
// the string gets parsed.
// if successful, you get a MutationData
// if failed (invalid input) you get a MutationError
