get static method

Future get(String key, { dynamic defaultValue, bool cache = true, })

Gets the value of a setting with the specified key.

Parameters:

• key: A unique key for the setting. It is case-insensitive and will be searched in lowercase.
• defaultValue: The default value to return if the setting is not found. Defaults to null.
• cache: Whether to cache the value in memory. Defaults to true.

Returns: The value of the setting or the default value if it is not found.

Implementation

static Future<dynamic> get(String key, {dynamic defaultValue, bool cache = true}) async {
  key = key.toLowerCase();

  if (cache && _cache.containsKey(key)) {
    return _cache[key];
  } else {
    final db = await DB.instance();
    final data = await db.kVs.where().keyEqualTo(key).findFirst();
    if (data != null) {
      final value = unserialize(data.value);
      _cache[key] = value;
      return value;
    } else {
      return defaultValue;
    }
  }
