Flutter 颤振:边界半径不';不要在showGeneralDialog下工作

Flutter 颤振:边界半径不';不要在showGeneralDialog下工作,flutter,border,showdialog,Flutter,Border,Showdialog,为什么showGeneralDialog下的BorderRadius不起作用这是我的代码-- import 'package:flutter/material.dart'; class MyHomePage extends StatefulWidget { MyHomePage({Key key, this.title}) : super(key: key); final String title; @override _MyHomePageState createStat
