Dart：如何将对象数组转换为哈希图数组？

我想将对象转换为哈希图，以便可以使用Flutter方法通道将数据发送到Android。

我已经考虑过逐一迭代并映射它们，但是必须有一种更优雅的方法来实现此目的...

例：

宾语

class Something {
  Something(this.what, this.the, this.fiddle);
  final String what;
  final int the;
  final bool fiddle;
}

别的地方

List listOStuff = List.generate(10, (int index){
  return Something(index.toString(), index, false,);
});

List> parseToMaps(List listOStuff){
  List> results;
  // do something crazy to get listOStuff into Map of primitive values for each object
  // preferably a built in method of some sort... otherwise, i guess i'll just iterate...
  // maybe even an imported package if such thing exists
  return results;
}

List> listOMaps = parseToMaps(listOStuff);

用Java这样的东西

您可以使用map并返回所需的对象：

    List> listOMaps = listOStuff
            .map((something) => {
                  "what": something.what,
                  "the": something.the,
                  "fiddle": something.fiddle,
                })
            .toList();
