Dart/Flutter - 如何删除列表中 Map 元素的键值对？

Question

How can I can delete a specific key-value-pair in that type of List<Map<String, dynamic>> for each map.

For example:

List<Map<String, dynamic>> before the operation:

List<Map<String, dynamic>> currencies = [
    {
      'id': 1,
      'name': 'coin',
      'desc': 'This is just a blindtext.',
      'order': 101,
      'icon': 'https://icon1.jpg'
    },
    {
      'id': 2,
      'name': 'karma',
      'desc': 'This is just a blindtext.',
      'order': 102,
      'icon': 'https://icon2.jpg'
    },
    {
      'id': 3,
      'name': 'laurel',
      'desc': 'This is just a blindtext.',
      'order': 104,
      'icon': 'https://icon3.jpg'
    },
  ];

List<Map<String, dynamic>> after the operation I am searching for:

List<Map<String, dynamic>> currencies = [
    {
      'id': 1,
      'name': 'coin',
      'icon': 'https://icon1.jpg'
    },
    {
      'id': 2,
      'name': 'karma',
      'icon': 'https://icon2.jpg'
    },
    {
      'id': 3,
      'name': 'laurel',
      'icon': 'https://icon3.jpg'
    },
  ];

So basically, I deleted "unwanted" key-value-pairs. Any suggestions?

Thanks in advance!!

Answer 1

currencies.forEach((item) => item..remove("order")..remove("desc"));
