Flutter 获取太多位置参数时出错

位置参数是如何工作的

children: <Widget>[
  Table(
    children: [
      _buildTableRow(
        'one',
        'two',
        'Three'
      ),
    ],
  ),
],

仅接受一个字符串
在您的代码中
您传递三个字符串

_buildTableRow(
    'one',
    'two',
    'Three'
  ),

你可以这样做

  _buildTableRow("one, two, Three")

完整代码

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      home: BasicTable(),
    );
  }
}


class BasicTable extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text("Table Widget")),
      body: Table(
        defaultColumnWidth: FixedColumnWidth(150.0),
        border: TableBorder(
          horizontalInside: BorderSide(
            color: Colors.black,
            style: BorderStyle.solid,
            width: 1.0,
          ),
          verticalInside: BorderSide(
            color: Colors.black,
            style: BorderStyle.solid,
            width: 1.0,
          ),
        ),
        children: [
          _buildTableRow("one, two, three"),
          _buildTableRow("Inducesmile.com, Google.com, Flutter.dev"),
          _buildTableRow("Inducesmile.com, Google.com, Flutter.dev"),
          _buildTableRow("Inducesmile.com, Google.com, Flutter.dev"),
        ],
      ),
    );
  }

  TableRow _buildTableRow(String listOfNames) {
    return TableRow(
      children: listOfNames.split(',').map((name) {
        return Container(
          alignment: Alignment.center,
          child: Text(name, style: TextStyle(fontSize: 20.0)),
          padding: EdgeInsets.all(8.0),
        );
      }).toList(),
    );
  }
}

然后像这样使用它：

_buildTableRow('one,two,Three')

嗨，警察路。关于这一点，我可以请你在CW答案中留下归属信息吗？它已经在Meta和SO CVR中讨论过。我认为大家的共识是，只有明确内容的作者，才能满足许可条件。如果您想阅读，我可以为您挖掘一个链接。@halfer您好，另一个用户（diegoveloper）已经提供了相同的答案，您提到“代表问题作者发布解决方案，将其从问题中移除”，但是OP更新了他的帖子（在该用户在评论中写道如何解决它之后），OP更新了帖子，那个用户把它写成了答案。希望我能澄清这一点。你上面的描述不是特别清楚，但读了几遍之后，我想我明白你的意思了——原始作者来自diegoveloper，而不是BloodLoss（OP），因此不需要归属。我不确定我是否同意，但正确的做法是不编辑这篇文章，并要求将其删除。（也许你确实要求删除它，因为有版主删除了它）。最后，我的主要观点是，如果你看到署名是故意添加的，最好不要删除它。在Meta上。@halfer是的，你明白我的意思了（即使我现在读它，我在第一次尝试lol时也没有弄清楚），很抱歉我以前不知道
