ZipFile.fromJson(Object? json_)

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

Implementation

factory ZipFile.fromJson(Object? json_) {
  final json = json_ is Map
      ? _spec.fields.map((f) => json_[f.label]).toList(growable: false)
      : json_;
  return switch (json) {
