JsonString extension type
A zero-cost wrapper around a JSON string.
This type exists to provide a subtype of JsonValue that is a string.
Constructors
- JsonString(String _value)
-
const
- JsonString.parse(String input)
-
Parses and casts the given
inputas a string.factory -
JsonString.parseUtf8(List<
int> bytes) -
Parses and returns the given UTF8-encoded
bytesas a string.factory
