toJson method

Implementation

core.Map<core.String, core.dynamic> toJson() {
  final derivatives = this.derivatives;
  final examples = this.examples;
  final senses = this.senses;
  final source = this.source;
  return {
    'derivatives': ?derivatives,
    'examples': ?examples,
    'senses': ?senses,
    'source': ?source,
  };
