键盘隐藏了Flutter TextField,请尝试许多解决方案但不起作用

flutter

当专注于TextField时,键盘将隐藏在TextField上方。下面我附上了带有代码的屏幕截图。请指导我解决此问题。

signup.dart

import 'package:flutter/material.dart';
import 'package:yfobs/utilities/desc.dart';

class SignUpPage extends StatefulWidget {
  static String tag = 'SignUpPage';
  @override
  _SignUpPageState createState() => _SignUpPageState();
}

class _SignUpPageState extends State<SignUpPage> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      resizeToAvoidBottomPadding: false,
      body: Container(
        width: double.infinity,
        decoration: BoxDecoration(
            gradient: LinearGradient(begin: Alignment.topCenter, colors: [
          Color(0xFF832685),
          Color(0xFFC81379),
        ])),
        child: Column(

你能用SingleChildScrollView包裹脚手架的主体并用ConstrainedBox包裹容器吗

这是我得到的输出https://prnt.sc/qozsvc

键盘仍将位于文本字段的顶部,但是通过使用SingleChildScrollView,屏幕将可滚动,因此您可以向下滚动并再次查看文本字段。

这个解决方案对我有用。

Scaffold(
  body: SingleChildScrollView(
    child: ConstrainedBox(
      constraints: BoxConstraints(maxHeight: MediaQuery.of(context).size.height),
      child: Container(
        .
        .
        .
