inherited
Return Json representation of TTMultiMap.
Node tree stored as preorder traversal.
If includeValues
is true then values are included and must be
Json serialisable in their own right.
Implementation
@override
Map<String, dynamic> toJson(
{bool includeValues = true,
dynamic Function(V value)? valueToEncodable}) {
ArgumentError.checkNotNull(includeValues, 'includeValues');
// Default value transform
valueToEncodable ??= (V e) => e;
final map = <String, dynamic>{};
final nodes = <List<dynamic>>[];
_toJson(_root, nodes, includeValues, valueToEncodable);
map[_JSONKEY_NODES] = nodes;
map[_JSONKEY_KEYMAPPING] = keyMapping(null);
return map;
