  1. String path

Assuming that this string is a json object or array, extracts a part of this structure identified by path.

For more details on how to format the path argument, see the sqlite documentation.

Evaluating this expression will cause an error if path has an invalid format or this isn't well-formatted json.

Note that the T type parameter has to be set if this function is used in JoinedSelectStatement.addColumns or compared via Expression.equals. The T parameter denotes the mapped Dart type for this expression, such as String.
