It would be great If Flutter Flow supports data type of Map<String, DataType>.
Example use-case is cache, which requires 'Key' to identify whether the value is cached.
JSON can be used for workaround, however we can not use custom DataType for JSON and
It requires conversion of custom DataType and JSON which makes things complex and slow downs development speed.
List<DataType> can be used for workaround, however it also requires additional mechanism for querying the list items by key.
