TableType.fromJson constructor

TableType.fromJson(Object? json_)

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

Implementation

factory TableType.fromJson(Object? json_) {
  final json = json_ is Map
      ? _spec.fields.map((f) => json_[f.label]).toList(growable: false)
      : json_;
  return switch (json) {
    [final element, final minimum, final maximum] ||
    (final element, final minimum, final maximum) =>
      TableType(
        element: RefType.fromJson(element),
        minimum: minimum! as int,
        maximum: Option.fromJson(maximum, (some) => some! as int).value,
      ),
    _ => throw Exception('Invalid JSON $json_')
  };
}
