processDynamicArgs method

DynamicParamsResult processDynamicArgs(dynamic args, { Set<String>? dynamicKeys, })

Processes any dynamic argument values from args. This will return a metadata object with the results as well as a collection of dynamic variable names that were encounted.

Implementation

DynamicParamsResult processDynamicArgs(
  dynamic args, {
