底部溢出 21 個像素的 RenderFlex

Question

我是 flutter 的新手，我嘗試使用網格視圖，但它顯示了一個渲染彎曲，底部溢出了 21 個像素。 在 GridView 我使用圖片，但它顯示錯誤。 誰知道怎么修它？ 謝謝

我在互聯網上搜索，它使用 SingleChildScrollView，但我不想使用它，因為網格視圖看起來很奇怪

這是我的代碼

import 'package:flutter/material.dart';
import 'package:monger_app/page/detail.dart';

class BudgetSettings extends StatefulWidget {
  @override
  _BudgetSettingsState createState() => _BudgetSettingsState();
}

class _BudgetSettingsState extends State<BudgetSettings> {
  List<Container> categorylist = new List();

  var character=[
    {"name":"Food", "image":"food.png"},
    {"name":"Social-Life", "image":"travel.png"},
    {"name":"Transportation", "image":"transportation.png"},
    {"name":"Beauty", "image":"makeup.png"},
    {"name":"Household", "image":"household.png"},
    {"name":"Education", "image":"education.png"},
    {"name":"Health", "image":"health.png"},
    {"name":"Gift", "image":"gift.png"},
    {"name":"Other", "image":"other.png"},
  ];
  _makelist() async {
    for (var i = 0; i < character.length; i++) {
      final newcharacter = character[i];
      final String image = newcharacter["image"];
      categorylist.add(
        new Container(
          padding: new EdgeInsets.all(20.0),
          child: new Card( child:
            new Column(
                  children: <Widget>[
                    new Image.asset('assets/$image', fit: BoxFit.cover,),
                    new Padding(padding: new EdgeInsets.all(5.0),),
                    new Text(newcharacter['name'], style: new TextStyle(fontSize: 18.0),),
                  ],
                ),
            ),
            )
        );
    }
  }

  @override
  void initState() {
    _makelist();
    super.initState();
  }
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Budget Setting'),
      ),

      body: new GridView.count(
          crossAxisCount: 2,
          children: categorylist,
      ),
    );
  }
}

這里是我的 output

您的問題的一個簡單解決方案是將您的圖像小部件包裝在一個靈活的小部件中，就像這樣：

Flexible(
  child: Image.asset('assets/$image', fit: BoxFit.cover,),
),
