get<T> method

T get<T>(String key, { T? def, })

Retrieves the value of key cast to type T. Supports type-specific operations.

Supported types include List, bool, int, double, and String.

Implementation

T get<T>(String key, {T? def}) {
  switch (T) {
    case List:
      var res = dataObject(key, def: def);
      if (res is List) {
        return res as T;
      }
      if (def != null) return def;
      return [] as T;
    case num:
      var res = (num.tryParse(data(key)) ?? -1);
      if (def != null && res == -1) return def;
      return res as T;
    case int:
      var res = (int.tryParse(data(key)) ?? -1);
      if (def != null && res == -1) return def;
      return res as T;
    case bool:
      return data(key).toBool as T;
    case String:
      var res = data(key).toString();
      if (res.isEmpty && def != null) return def;
      return res as T;
    default:
      return data(key) as T;
  }
}
