  IconButton实际上会实现您的目标！

  根据指南，FloatingActionButton将始终提供您在"View in Your Room" Headers 按钮上找到的设计 .

  IconButton(
    icon: Icon(Icons.back),
    onPressed...
  )

  为此，您可以使用 **actions ** property of appbar to put icons on the right side of title and leading 属性放置一个前导图标 .

  appbar: new AppBar(
      leading: new Icon(Icons.search),
      actions: <Widget>[
                           new Icon(Icons.search),
                           new Icon(Icons.search),
                   ],
     title: new Text("title"),
  )

  您需要使用IconButton，如下所示

  // Icon Button
  new IconButton(
            icon: new Icon(Icons.favorite),
            tooltip: 'Facorite icon',
            color: Colors.blue, //set color which you want
            onPressed: () {
               // Do your work 
            },
  ),
