Flutter-布置网格 [英] Flutter - Layout a Grid

问题描述

我正在尝试在颤动中布置4x4的瓷砖网格。我设法做到了列和行。但是现在我发现了 GridView 组件。谁能提供使用它的示例吗？

I am trying to layout a 4x4 grid of tiles in flutter. I managed to do it with columns and rows. But now I found the GridView component. Could anyone provide an example on how to do it using it?

我真的无法将自己的头围在文档上。我似乎没有得到想要的结果。

I can't really wrap my head around the docs. I don't seem to get the results I want.

推荐答案

将图像加载到图块的简单示例。

A simple example loading images into the tiles.

import 'package:flutter/material.dart';

void main() {
  runApp( MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(

      color: Colors.white30,
      child: GridView.count(
          crossAxisCount: 4,
          childAspectRatio: 1.0,
          padding: const EdgeInsets.all(4.0),
          mainAxisSpacing: 4.0,
          crossAxisSpacing: 4.0,
          children: <String>[
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
            'http://www.for-example.org/img/main/forexamplelogo.png',
          ].map((String url) {
            return GridTile(
                child: Image.network(url, fit: BoxFit.cover));
          }).toList()),
    );
  }
}

Flutter Gallery应用程序包含一个真实的示例，可以在此处。

The Flutter Gallery app contains a real world example, which can be found here.
