QueryParameterEncoder<T> typedef
QueryParameterEncoder<T> =
String Function(T value)
Signature of custom query parameter encoding.
The function takes a parameter value of type T and returns a string
representation suitable for use in a URI. The returned string is escaped to
be URL-safe.
For example, a parameter value of 'field with space' will generate a query
parameter value of 'field+with+space'.
Implementation
typedef QueryParameterEncoder<T> = String Function(T value);
