T? get<T>(String key, { T from(Map map)?, T? defValue, })

获取数据

Implementation

static T? get<T>(String key, {T from(Map map)?, T? defValue}) {
  final read = GetStorage().read(key);
  if (read == null) {
    if (key != 'XSpKey.OssImageUrl')
      XLog.d('没有查询到数据,key=$key');
    return defValue;
  }
  if (read is Map) {
    if (read is T) {
      return read as T;
    }

    if (from == null) {
      XLog.d('需要将 jsonMap 转为 对象 $T 的 from 函数');
    }
    return from?.call(read) ?? defValue;
  }
  if (read is List) {
    XLog.e('需使用 getList 来获取List');
    return null;
  }
  return read;
