如何更改 CheckboxListTile 高度？

Question

很快，我需要可選區域在高度方面更小。

文本和復選框大小很好，但周圍的框對於我嘗試創建的清單來說太大了。

CheckBoxListTile 當前高度與所需高度

嘗試用 Transform.scale 包裝它，但文本變得太小：

Transform.scale(
  scale: 0.8,
  child: CheckboxListTile(
    title: const Text("Rinite alérgica"),
    value: timeDilation != 1.0,
    controlAffinity: ListTileControlAffinity.leading,
    onChanged: (bool value) {
      setState(() {
      timeDilation = value ? 2.0 : 1.0;
      });
    },
  ),
),

嘗試用 Container 包裝它，但我在屏幕上收到溢出警告。

有沒有人有更好的解決方案？

Answer 1

你有沒有嘗試過 ？

SizedBox(
  height: 50,
  width: 50,
  child: ......
)

Answer 2

當嘗試調整CheckboxListFile大小時，似乎 Google 實際上建議創建自定義 Tile 小部件並使用Checkbox小部件。

https://api.flutter.dev/flutter/material/CheckboxListTile-class.html#material.CheckboxListTile.3

查看已創建的 LabeledCheckbox 小部件。 您可以非常輕松地修改所有組件以滿足您的需要。 例如，如果您希望 Widget 本身更小，您現在可以將其包裝在一個 Container 中

/// Flutter code sample for CheckboxListTile

// ![Custom checkbox list tile sample](https://flutter.github.io/assets-for-api-docs/assets/material/checkbox_list_tile_custom.png)
//
// Here is an example of a custom LabeledCheckbox widget, but you can easily
// make your own configurable widget.

import 'package:flutter/material.dart';

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

/// This is the main application widget.
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Code Sample';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const Center(
          child: MyStatefulWidget(),
        ),
      ),
    );
  }
}

class LabeledCheckbox extends StatelessWidget {
  const LabeledCheckbox({
    Key key,
    @required this.label,
    @required this.padding,
    @required this.value,
    @required this.onChanged,
  }) : super(key: key);

  final String label;
  final EdgeInsets padding;
  final bool value;
  final Function onChanged;

  @override
  Widget build(BuildContext context) {
    return InkWell(
      onTap: () {
        onChanged(!value);
      },
      child: Container(
        padding: padding,
        child: Row(
          children: <Widget>[
            Expanded(child: Text(label)),
            Checkbox(
              value: value,
              onChanged: (bool newValue) {
                onChanged(newValue);
              },
            ),
          ],
        ),
      ),
    );
  }
}

/// This is the stateful widget that the main application instantiates.
class MyStatefulWidget extends StatefulWidget {
  const MyStatefulWidget({Key? key}) : super(key: key);

  @override
  State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}

/// This is the private State class that goes with MyStatefulWidget.
class _MyStatefulWidgetState extends State<MyStatefulWidget> {
  bool _isSelected = false;

  @override
  Widget build(BuildContext context) {
    return LabeledCheckbox(
      label: 'This is the label text',
      padding: const EdgeInsets.symmetric(horizontal: 20.0),
      value: _isSelected,
      onChanged: (bool newValue) {
        setState(() {
          _isSelected = newValue;
        });
      },
    );
  }
}
