Static Methods
-
localJsonToModel<
T> (String assetPath, T fromJson(Map< String, dynamic> ), {bool fromSandbox = false}) → Future<T?> - 定义一个通用的 JSON 数组解析为对象的方法
-
localJsonToModels<
T> (String assetPath, T fromJson(Map< String, dynamic> ), {bool fromSandbox = false}) → Future<List< T> > - 定义一个通用的 JSON 数组解析为对象List的方法
-
readJsonFromFile(
String filePath) → Map< String, dynamic> ? - 从文件中读取JSON数据 filePath: 文件路径 返回解析后的Map<String, dynamic>，如果读取失败返回null
-
writeJsonToFile(
Map< String, dynamic> json, String filePath) → bool - 写入JSON到文件 filePath: 文件路径 json: 要写入的JSON数据
