Flutter Wrap 導致右溢出

Question

我有個問題。 我最近開始使用 flutter，我真的很了解這個框架，但是這幾天，我一直在為一個問題苦苦掙扎。 我正在嘗試構建以下頁面：

所以我有這段代碼應該構建它：

import 'package:test/models/choice_chip_data.dart';
import 'package:test/styles/button_style.dart';
import 'package:test/widgets/reservation_person_selection.dart';
import 'package:test/widgets/reservation_time_selection.dart';
import 'package:test/widgets/restaurant_rating.dart';
import 'package:flutter/material.dart';
import 'package:intl/intl.dart';

final DateFormat formatter = DateFormat('dd-MM-yyyy');

class RestaurantReservationDetailsPage extends StatefulWidget {
  @override
  _RestaurantReservationDetailsPageState createState() =>
      _RestaurantReservationDetailsPageState();
}

class _RestaurantReservationDetailsPageState
    extends State<RestaurantReservationDetailsPage> {
  DateTime? reservationDateTime;
  List<ChoiceChipData> timeChips = [
    ChoiceChipData(
        label: "17:00",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue),
    ChoiceChipData(
        label: "17:30",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue),
    ChoiceChipData(
        label: "18:00",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue),
    ChoiceChipData(
        label: "18:30",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue),
    ChoiceChipData(
        label: "19:00",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue),
    ChoiceChipData(
        label: "19:30",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue),
    ChoiceChipData(
        label: "20:00",
        isSelected: false,
        textColor: Colors.black,
        selectedColor: Colors.blue)
  ];

  @override
  void dispose() {
    super.dispose();
  }

  @override
  initState() {
    super.initState();

  @override
  Widget build(BuildContext context) {

                                ? "Datum kiezen"
                                : formatter.format(reservationDateTime!)),
                            btnAction: () => {
                                  showDatePicker(
                                          context: context,
                                          initialDate: DateTime.now(),
                                          firstDate: DateTime.now(),
                                          lastDate: DateTime.now()
                                              .add(Duration(days: 14)))
                                      .then((date) => {
                                            setState(() {
                                              reservationDateTime = date;
                                            })
                                          })

                                fontSize: 16)),
                        SizedBox(height: 5),
                        buildChoiceChips(),
                      ],
                    )
                  ],
                ),
              )
            ],
          )
        ],
      )
    ])));
  }

  Widget buildChoiceChips() => Wrap(
      runSpacing: 5,
      spacing: 5,
      children: timeChips
          .map((timeChip) => ChoiceChip(
              label: Text(timeChip.label),
              labelStyle:
                  TextStyle(fontWeight: FontWeight.bold, color: Colors.black),
              onSelected: (isSelected) => setState(() {
                    timeChips = timeChips.map((otherChip) {
                      final newChip = otherChip.copy(isSelected: false);

                      return timeChip == newChip
                          ? newChip.copy(isSelected: isSelected)
                          : newChip;
                    }).toList();
                  }),
              selected: timeChip.isSelected))
          .toList());
}

現在一切正常，除了時間芯片在右側溢出，如下所示：

我已經閱讀了有關可能導致問題的 Row() 的內容： https://stackoverflow.com/a/58494435/10673107 ，但這對我不起作用！

如何修復溢出？

Answer 1

行導致問題

Container(
      padding: EdgeInsets.only(left: 30, right: 30),
        child: Row(
               children: [
                   Column(

它提供了 wrap 無限的水平長度，這使 wrap 無需開始在新行中對齊。

將此處的行刪除為這樣的內容

Container(
      padding: EdgeInsets.only(left: 30, right: 30),
        child: Column(

我建議你使用 Wrap

Wrap(children: [
      ...,
      ...
    ]),
