JsonEncoder constructor Null safety

const JsonEncoder(
  1. [Object? toEncodable(
    1. dynamic object
    )]
)

Creates a JSON encoder.

The JSON encoder handles numbers, strings, booleans, null, lists and maps with string keys 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

const JsonEncoder([Object? toEncodable(dynamic object)?])
    : indent = null,
      _toEncodable = toEncodable;
