# JsonUtf8Encoder constructor Null safety

JsonUtf8Encoder(

1. [String? indent,
2. dynamic toEncodable(
   1. dynamic object
   ),
3. int? bufferSize]

)

Create converter.

If `indent` is non-`null`, the converter attempts to "pretty-print" the JSON, and uses `indent` as the indentation. Otherwise the result has no whitespace outside of string literals. If `indent` contains characters that are not valid JSON whitespace characters, the result will not be valid JSON. JSON whitespace characters are space (U+0020), tab (U+0009), line feed (U+000a) and carriage return (U+000d) (ECMA 404).

The `bufferSize` is the size of the internal buffers used to collect UTF-8 code units. If using startChunkedConversion, it will be the size of the chunks.

The JSON encoder handles numbers, strings, booleans, null, lists and maps directly.

Any other object is attempted converted by `toEncodable` to an object that is of one of the convertible types.

If `toEncodable` is omitted, it defaults to calling `.toJson()` on the object.

## Implementation

    JsonUtf8Encoder(
        [String? indent, dynamic toEncodable(dynamic object)?, int? bufferSize])
        : _indent = _utf8Encode(indent),
          _toEncodable = toEncodable,
          _bufferSize = bufferSize ?? _defaultBufferSize;
