Flutter - 在无状态小部件中动态地将项目添加到 ListView

Question

Sorry for my bad English. I'm creating a Flutter application. And I have a route to Stateless widget from Stateful widget. I have a ListView with data. And I want to add items dynamically. But I added a ListView to Stateless Widget. Because route to Stateful widget doesn't work.

How can I do it? Thanks.

Firstly you must show some of your code.

You choose basically convert Stateless Widget to Stateful Widget and define a variable listItem. Then you can call setState after adding some item to your variable.

Otherwise, I recommend using State Management packages, etc. GetX, BLoC, or Provider. You can research them.
