signal method

Map<K, V> signal({
  1. String field = "",
  2. Type at = Null,
  3. String debugLabel = "",
})

在自定义Store时需提供field at，会注册字段

Implementation

Map<K, V> signal({String field = "", Type at = Null, String debugLabel = ""}) {
  var data = _Map(this, debugLabel: debugLabel);
  return data;
}
