kfromJsonMap<K, T> method

Map<K, T?>? kfromJsonMap<K, T>()

json转Map<K, T?>，T = 原始数据类型

  Map<String, int?>? map = mapStr.kfromJsonMap()
  Map<String, String?>? map = mapStr.kfromJsonMap()
  Map<int, int?>? map = mapStr.kfromJsonMap()
  ....

Implementation

Map<K, T?>? kfromJsonMap<K, T>() {
  var file = this;
  if (file == null || file.isEmpty) {
    return null;
  }
  Map map = jsonDecode(file);
  var newMap = <K, T?>{};
  map.forEach((key, value) {
    newMap[key] = value;
  });
  return newMap;
}
