如何在Flutter中构建动态列表？

您可以使用它setState来重建UI.

例:

class TestList extends StatefulWidget {

  final Future quiz;

  TestList({this.quiz});

  @override
  _TestListState createState() => new _TestListState();

}

class _TestListState extends State {

  bool loading = true;

  _TestListState(){
    widget.quiz.then((List value) {

      // loop through the json object
      for (var i = 0; i  listArray = [];

    return new Container(
        child: new ListView(
            children: loading?[]:listArray     // when the state of loading changes from true to false, it'll force this widget to reload
        ));

  }

}
