Flutter 键盘遮挡住了控件

Flutter中使用TextField输入框，会有键盘遮挡问题：

      TextField(
              decoration: InputDecoration(
//                  labelText: "密码",
                  hintText: "您的登录密码",
                  prefixIcon: Icon(Icons.lock)),
              obscureText: true,
            ),
            SizedBox(
              height: 40,
            ),

遮挡键盘的图片

解决方案：

在页面的Scaffold里面添加属性：

resizeToAvoidBottomInset: false,

修改后的结果：

修改后就不在遮挡控件

源码：

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class LoginPage extends StatefulWidget {
  String title = "Login";

  LoginPage({Key key, this.title}) : super(key: key);

  @override
  _LoginPageState createState() => _LoginPageState();
}

class _LoginPageState extends State<LoginPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      resizeToAvoidBottomInset: false,
      body: Center(
        child: Column(
