Flutter：如何禁用 GridView 小部件的滚动，但使整个页面可以滚动？

Question

我正在开发一个应用程序，其中有一个页面提供有关特定交易卡的信息。我希望该页面可以滚动，但我还想在页面上放置一个网格，每个网格单元格显示一个数据点。我使用GridView.count()制作了网格。

我的问题是，页面的顶部一半保持静态，而网格可以滚动。如何使网格保持静态，而页面其余部分可滚动？我打算在此网格下方添加更多数据，并希望用户能够滚动查看所有内容，而网格成为页面的静态组件。

以下是我的代码：

import 'package:flutter/material.dart';
import 'package:pokehub/size_config.dart';
import 'package:pokemon_tcg/pokemon_tcg.dart';

class CardInfo extends StatefulWidget {
  PokemonCard card;

  CardInfo({required this.card});

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

class _CardInfoState extends State<CardInfo> {
  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: Scaffold(
        backgroundColor: Colors.grey[900],

Answer 1

您可以在 GridView 上提供 physics: NeverScrollableScrollPhysics() 来禁用滚动效果。如果您想要作为次要小部件具有可滚动性，则使用 primary: false,

要实现整个页面可滚动，您可以使用 body:SingleChildScrollView(..) 或更好的方法是使用 body: CustomScrollView(..)。

尝试这个：

class CardInfo extends StaefulWidget {
  PokemonCard card;

  CardInfo({required this.card});

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

class _CardInfoState extends State<CardInfo> {
  @override
