在 Flutter redux 中比较旧视图模型和当前视图模型

Question

在Flutter-redux中，我们可以使用onDidChange和onWillChange来检测store state的变化。但是有没有办法检测特定属性的变化？

我可以做类似

的事情吗

if(oldViewModel.changedProperty != viewModel.changedProperty)

在 react-redux 中，可以检查 prevProps 和 currProps 的差异并根据差异执行操作。

Answer 1

// As a performance optimization, the Widget can be rebuilt only when the
// [ViewModel] changes. In order for this to work correctly, you must
// implement [==] and [hashCode] for the [ViewModel], and set the [distinct]
// option to true when creating your StoreConnector.

StoreConnector<AppState, AppState>(
              distinct: true,
              converter: (store) => store.state,
              builder: ),
