YTextEvent.fromJson constructor

YTextEvent.fromJson(
  1. Object? json_
)

Returns a new instance from a JSON value. May throw if the value does not have the expected structure.

Implementation

factory YTextEvent.fromJson(Object? json_) {
  final json = json_ is Map
      ? _spec.fields.map((f) => json_[f.label]).toList(growable: false)
      : json_;
  return switch (json) {
    [final target, final delta, final path] ||
    (final target, final delta, final path) =>
      YTextEvent(
        target: YText.fromJson(target),
        delta: (delta! as Iterable).map(YTextDelta.fromJson).toList(),
        path: (path! as Iterable).map(EventPathItem.fromJson).toList(),
      ),
    _ => throw Exception('Invalid JSON $json_')
  };
}
