如何在 Dart 中将 List <String> 转换为 Map <String,String>？[重复]

  • 772

我有List<String> = ["name","class","age"];

我希望此列表转换为Map<String,String>;

喜欢Map<String,String>["name":"name","class":"class","age":"age"];

如何实现这一点？

dart

  1. 其中一种方法是：

    void main() {
  List<String> list = ["name", "class", "age"];

  Map<String, String> map = {
    for (final entry in list) entry: entry,
  };

  print(map); // {name: name, class: class, age: age}
}

    我以前也遇到过这种情况。下面是我处理的方法。

    List<String> list = ["name", "class", "age"];

// Convert the list to a map
Map<String, String> map = Map.fromIterable(
  list,
  key: (item) => item,
  value: (item) => item,
);

// Print the map (You can use this map in your Flutter app)
print(map);

    输出：{name: name, class: class, age: age}

    快乐地飘舞！
