flutter - 有问题的具体 RenderFlex 是：RenderFlex#1c11f OVERFLOWING

Question

我试图在 Column 中添加一堆小部件，而根小部件是 Material。简单的代码抛出错误，我不明白它为什么会导致错误。我的代码是：

import 'dart:math';

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Material(
      child: Container(
        child: Column(
          children: [
            Text('234')
          ],
        ),
      )
    );
  }
}

错误是：

════════ Exception caught by rendering library ═════════════════════════════════
A RenderFlex overflowed by 99263 pixels on the bottom.
The relevant error-causing widget was
    Column 
lib\main.dart:14
The specific RenderFlex in question is: RenderFlex#1c11f OVERFLOWING

我的代码有什么问题？

这里的问题是，您的 Column 具有无限的高度。

你可以做的一些事情：

• 把所有东西都放在一个Scaffold body
• 将height属性添加到您的Container
• 给mainAxisSize: MainAxisSize.min你Column
