【问题描述】：

我以前从未使用过 JSON，所以我不熟悉它的语法。

目前我有多个包含不同数据的数组。

我想创建一个 JSON 对象，其中包含多个数组，每个数组都有几条数据。例如。一个名为 HotelList 的对象，包含多个数组，每个数组对应不同的酒店名称。看例子：

class Jsons {
  static var hotelListJson = {
    'hotelData': [
      {
        'index': 0,
        'restaurantName': 'Monginis Cake Shop',
        'foodCategory': 'The Cake Shop',
        'restReview': 5,
        'restImage': 'assets/images/Restaurant1.png',
        'distanceFromLocation': 40,
        'restStatus': 'open',
        'menuCategories': [
          {
            'categoryName': 'Pastry',
            'dishes': [
              'Dutch Pastry',
              'Truffle Pastry',
              'Pipeapple Veg Pastry',
              'Brownee Sqare Veg Pastry',
              'Choco Lava Veg Cup'
            ],
          },
          {
            'categoryName': 'small cake ( half kg)',
            'dishes': [
              'Sapphire Veg Small',
              'Deviles Delite Veg Small',
              'Duth Chocolate Heart Veg (Small)',
              'Shimmer Choco Veg Small'
            ]
          },
          {
            'categoryName': 'Breads',
            'dishes': ['Sandwich Bread', 'Multigrain Bread', 'Brown Bread']
          },
          {
            'categoryName': 'Large cake',
            'dishes': ['Alpine Choco Veg(Large)']
          },
          {
            'categoryName': 'Cookies',
            'dishes': [
              'Almond Cocos Cookies',
              'Shewsburry Cookies',
              'Honey Crunch Cookis',
              'Kesar Cookies',
              'Jeeraa Cookies'
            ]
          },
          {
            'categoryName': 'Savouries',
            'dishes': [
              'Panner pattice',
              'Veg Burger',
              'Pan Pizza Veg',
              'Veg pattice'
            ]
          },
          {
            'categoryName': 'Chocolate',
            'dishes': ['Just Temptations']
          },
          {

            'dishes': ['Fruit Bar cake']
          },
        ]
      },
      {
        'index': 1,
        'restaurantName': 'Swami Hotel',
        'foodCategory': 'Family Hotel',
        'restReview': 2,

        'distanceFromLocation': 40,
        'restStatus': 'open',
        'menuCategories': [
          {
            'categoryName': 'Veg Starter',
            'dishes': [ 'Paneer pahadi kabab','Garlic chana','Masala papad', 'Manchurian']
          },
          {
            'categoryName': 'Tandoori',
            'dishes': ['Chicken Tandoori','Chicken Tangadi Kabab','Chicken Pahadi Kabab','Mutton Kadhai]
          },
          {
            'categoryName': 'INDIAN BREAD',
            'dishes': ['Aalu Paratha','Paneer Paratha','Nan', 'Butter Nan','Tandoori Roti','Chapati']
          },         
        ]
      },
      {
        'index': 2,
        'restaurantName': 'Diva Sagar',
        'foodCategory': 'Family restaurant',
        'restReview': 5,
        'restImage': 'assets/images/Restaurant3.png',
        'distanceFromLocation': 30,
        'restStatus': 'open',
      },
      {
        'index': 3,
        'restaurantName': 'Smart open pick cake shop',
        'foodCategory': 'Cake Shop',
        'restReview': 1,

        'restStatus': 'closed',
        'offer': 'Get 5% discount',
      },
    ]
  };
}

它和你的 json 一样复杂使用https://javiercbk.github.io 我创建了一个很长的类，所以我不会发布它，但是如果你为它创建一个类，你可以自己尝试一下，你可以添加删除，实际上是所有的东西

您的 json 有问题，我无法在该网站上使用它，请查看我的 json 并更正您的 json
