开发

开发中，可以选择开启自动生成model，修改了model定义，会自动生成 fromJson 方法 开启命令：

flutter packages pub run build_runner watch

说明

不使用 json_serializable

1 因为它生成的代码，大量使用as，如：

EpisodeModel _$EpisodeModelFromJson(Map<String, dynamic> json) {
  return EpisodeModel(json['sid'] as String, json['title'] as String,
      json['createdAt'] as String);
}

2 因为它生成的函数中，如果传入的json为null，还是会报错

推荐下面这样写，是最简洁的写法了，虽然属性不能用final定义了

import 'EpisodeModel.dart';

class ChannelModel {
  String sid = '';
  String name = '';
  EpisodeModel episodes = EpisodeModel.fromJson(null);

  ChannelModel.fromJson(Map<String, dynamic> json) {
    if(json != null){
      sid = json['sid'] ?? sid;
      name = json['name'] ?? name;
      episodes = EpisodeModel.fromJson(json['episodes']);
    }
  }
}
