颤动键盘的高度增加了两倍

Question

最近遇到一个问题，当键盘显示在聚焦TextField时，应用程序将键盘的底部填充两倍。这取代了TabBar并扩展了ListViews。一旦我专注于TextField，它就会影响所有显示。

No Keyboard

Keyboard Up

当我将Gradle更新为4.1以尝试使用google_sign_in插件时，似乎出现了问题。

以下是我的main_screen.dart

/*Widget PopUpMenu<Menu>() {

这是我用来演示的测试页

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

class PageSplash extends StatefulWidget{


  @override
  State createState() {
    return new PageSplashState();
  }
}

class PageSplashState extends State<PageSplash> {
  @override
  Widget build(BuildContext context) {
    return new Container(
      child: new TextField(),
    );
  }
}

非常感谢你。
