運(yùn)行編寫了一個(gè)listview代碼簡(jiǎn)易的很(對(duì)著練),繼承StatefulWidget（動(dòng)態(tài)變化）方法

跳轉(zhuǎn)頁(yè)面是經(jīng)過(guò)路由進(jìn)行跳轉(zhuǎn)：

 點(diǎn)擊事件  onPressed
跳轉(zhuǎn)：Navigator.of(context).push(）；

跳轉(zhuǎn)代碼 替換build：

@override
  Widget build(BuildContext context) {
    return  Scaffold(
      appBar:  AppBar(
        title: const Text('Startup Name Generator'),
        actions: <Widget>[
           IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),
        ],
      ),
      body: _buildSuggestions(),
    );
  }

_pushSaved方法:

void _pushSaved() {
    Navigator.of(context).push(
       MaterialPageRoute<void>(
        builder: (BuildContext context) {
          final Iterable<ListTile> tiles = _saved.map(
                (WordPair pair) {
              return  ListTile(
                title:  Text(
                  pair.asPascalCase,
                  style: _biggerFont,
                ),
              );
            },
          );
          final List<Widget> divided = ListTile
              .divideTiles(
            context: context,
            tiles: tiles,
          )
              .toList();
          return  Scaffold(
            appBar:  AppBar(
              title: const Text('Saved Suggestions'),
            ),
            body:  ListView(children: divided),
          );
        },
      ),
    );
  }
