Dynamic Mutations

Just like Dynamic Queries, MutationJob.withVariableKey makes the mutation dynamic. Both of them are completely same

final mutationVariableKeyJob = MutationJob.withVariableKey<String, double>(
  preMutationKey: "mutation-example",
  task: (mutationKey, variables) {
    return MyAPI.submit({...variables, id: getVariable(mutationKey)});
  },
);

In the case of Mutation, we've preMutationKey instead of preQueryKey

You can use the dynamic Mutation Job just like any other MutationJob except you've to invoke the defined dynamic mutation & pass the variable-mutation-key as the first argument.

MutationBuilder<String, double>(
  job: mutationVariableKeyJob(id),
  builder: (context, mutation) {...},
)
