Answer 1

这对我有用

Row(
              children: <Widget>[
                RaisedButton(
                  onPressed: () {
                    Route route =
                        MaterialPageRoute(builder: (context) => MinionFlare());
                    Navigator.push(context, route);
                  },
                  child: SizedBox(
                    width: MediaQuery.of(context).size.width * 0.4,
                    child: Text("Minion"),
                  ),
                ),
                RaisedButton(
                  onPressed: () {
                    Route route = MaterialPageRoute(
                        builder: (context) => EmojiRatingBar());
                    Navigator.push(context, route);
                  },
                  child: SizedBox(
                      width: MediaQuery.of(context).size.width * 0.4,
                      child: Text("Emoji")),
                ),
              ],
            ),

Answer 4

您可以在每个按钮上加上“展开”。

Row(
children : <Widget>[
 Expanded(
    child: Button(
            child: Text("Clear")
           )
         ),
Expanded(
    child: Button(
            child: Text("Filter")
           )
         ),
])
