Flutter系统设置插件settings_tiles的使用
Flutter系统设置插件settings_tiles的使用
settings_tiles 是一个用于轻松创建设置屏幕的Flutter插件。它提供了多种类型的设置瓷砖（tiles），包括文本、操作、开关、复选框、单选项、多选项、文本字段、滑块、颜色选择器和关于应用程序的信息。
安装
请参阅 安装说明 来了解如何在你的项目中添加 settings_tiles 依赖。
使用
Section
创建一个设置部分，显示一组设置瓷砖，并可选地用分隔线分开，并在顶部有一个标题：
SettingSection(
title: 'A setting section',
tiles: [
// A list of tiles
],
)
要移除设置瓷砖之间的分隔线，请将 divider 参数设置为 null。
Tiles
Text
一个仅显示文本且没有交互的简单瓷砖：
const SettingTextTile(
icon: Icons.abc,
title: 'Text',
description: 'This is a text tile',
)
Action
当点击时调用某个动作的瓷砖：
SettingActionTile(
icon: Icons.touch_app,
title: 'Action',
description: 'This is an action tile',
onTap: () {
print('The action tile was tapped');
},
),
Switch
显示一个开关的瓷砖：
SettingSwitchTile(
icon: Icons.toggle_on,
title: 'Switch',
description: 'This is a switch tile',
toggled: true,
onChanged: (value) {
// Handle state change
},
)
Checkbox
显示一个复选框的瓷砖：
SettingCheckboxTile(
icon: Icons.check_box,
title: 'Checkbox',
description: 'This is a checkbox tile',
checked: true,
onChanged: (value) {
if (value == null) {
return;
}
// Handle state change
},
)
Single Option
显示一个对话框以选择单个选项的瓷砖：
SettingSingleOptionTile(
icon: Icons.radio_button_on,
title: 'Single option',
description: 'This is a single option tile',
dialogTitle: 'Options',
options: const ['Option 1', 'Option 2', 'Option 3'],
initialOption: 'Option 1',
onSubmitted: (value) {
// Handle state change
},
)
详细构造函数允许你指定每个选项的标题和可选的副标题：
SettingSingleOptionTile.detailed(
icon: Icons.radio_button_on,
title: 'Single option (detailed)',
description: 'This is a detailed single option tile',
dialogTitle: 'Options',
options: const [
(value: 'Option 1', title: 'Option n°1', subtitle: 'This is option n°1'),
(value: 'Option 2', title: 'Option n°2', subtitle: 'This is option n°2'),
(value: 'Option 3', title: 'Option n°3', subtitle: 'This is option n°3'),
],
initialOption: selectedOption,
onSubmitted: (value) {
// Handle state change
},
),
Multiple Options
显示一个对话框以选择多个选项的瓷砖：
SettingMultipleOptionsTile(
icon: Icons.checklist,
title: 'Multiple options',
description: 'This is a multiple options tile',
dialogTitle: 'Options',
options: const ['Option 1', 'Option 2', 'Option 3'],
initialOptions: const ['Option 1', 'Option 3'],
onSubmitted: (value) {
// Handle state change
},
)
详细构造函数允许你指定每个选项的标题和可选的副标题：
SettingMultipleOptionsTile.detailed(
icon: Icons.checklist,
title: 'Multiple options (detailed)',
description: 'This is a detailed multiple options tile',
dialogTitle: 'Options',
options: const [
(value: 'Option 1', title: 'Option n°1', subtitle: 'This is option n°1'),
(value: 'Option 2', title: 'Option n°2', subtitle: 'This is option n°2'),
(value: 'Option 3', title: 'Option n°3', subtitle: 'This is option n°3'),
],
initialOptions: const ['Option 1', 'Option 3'],
onSubmitted: (value) {
// Handle state change
},
),
Text Field
显示一个包含文本字段的对话框的瓷砖：
SettingTextFieldTile(
icon: Icons.text_fields,
title: 'Text field',
description: 'This is a text field tile',
dialogTitle: 'Text',
initialText: 'Some text',
onSubmitted: (value) {
// Handle state change
},
)
Slider
显示一个包含滑块的对话框的瓷砖：
SettingSliderTile(
icon: Icons.linear_scale,
title: 'Slider',
description: 'This is a slider tile',
dialogTitle: 'Slider',
min: 1.0,
max: 10.0,
divisions: 9,
initialValue: 5.0,
onSubmitted: (value) {
// Handle state change
},
)
Color Picker
显示一些颜色选择器和所选颜色预览的对话框的瓷砖：
SettingColorTile(
icon: Icons.color_lens,
title: 'Color',
description: 'This is a color tile',
dialogTitle: 'Color',
initialColor: Colors.blue,
onSubmitted: (value) {
// Handle state change
},
)
要更改可用的颜色选择器，请设置 colorPickers 参数。若要启用所有颜色选择器，请将其设置为 ColorPickerType.values。
About
显示应用程序信息并在点击时打开 Flutter 的 AboutDialog 的瓷砖：
const SettingAboutTile(
applicationIcon: Image.asset('assets/icon/icon.png'),
title: 'Application name',
description: 'v1.0.0',
)
需要将应用程序名称传递给 title 参数，并将版本传递给 description 参数。

当然，下面是一个关于如何在Flutter应用中使用settings_tiles插件的示例代码。settings_tiles是一个方便创建系统设置界面的Flutter插件，允许开发者以类似于Android系统设置页面的方式展示设置项。
首先，你需要在你的pubspec.yaml文件中添加对settings_tiles的依赖：
dependencies:
flutter:
sdk: flutter
settings_tiles: ^2.0.0 # 请检查最新版本号并替换
然后运行flutter pub get来获取依赖。
接下来，我们编写一个简单的Flutter应用，展示如何使用settings_tiles。
main.dart
import 'package:flutter/material.dart';
import 'package:settings_tiles/settings_tiles.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Settings Tiles Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: SettingsScreen(),
);
}
}
class SettingsScreen extends StatefulWidget {
@override
_SettingsScreenState createState() => _SettingsScreenState();
}
class _SettingsScreenState extends State<SettingsScreen> {
bool _switchValue = false;
String _textFieldValue = "";
void _onSwitchChanged(bool value) {
setState(() {
_switchValue = value;
});
}
void _onTextFieldChanged(String value) {
setState(() {
_textFieldValue = value;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Settings'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: ListView(
children: <Widget>[
SettingsTile.switchTile(
title: 'Switch Setting',
switchValue: _switchValue,
onToggle: _onSwitchChanged,
),
SettingsTile.header(title: 'Text Settings'),
SettingsTile.textTile(
title: 'Text Setting',
initialValue: _textFieldValue,
onSaved: (String value) {
_onTextFieldChanged(value);
},
),
SettingsTile.header(title: 'Number Settings'),
SettingsTile.sliderTile(
title: 'Slider Setting',
initialValue: 50.toDouble(),
min: 0.toDouble(),
max: 100.toDouble(),
onChanged: (double value) {
// Handle slider value change
print("Slider value: $value");
},
),
],
),
),
);
}
}
解释
- 依赖添加：首先在
pubspec.yaml中添加settings_tiles依赖。 - 应用结构：
MyApp是一个简单的Material应用，设置了主题并指定了主页为SettingsScreen。SettingsScreen是一个有状态组件，管理开关和文本字段的状态。
- SettingsTiles的使用：
SettingsTile.switchTile：创建一个开关设置项，绑定到_switchValue，并在开关值变化时调用_onSwitchChanged。SettingsTile.header：添加一个头部，用于分组设置项。SettingsTile.textTile：创建一个文本设置项，绑定到_textFieldValue，并在文本变化时调用_onTextFieldChanged。SettingsTile.sliderTile：创建一个滑块设置项，并处理滑块值的变化。
这个例子展示了如何使用settings_tiles插件创建一些基本的系统设置项。你可以根据需要进一步自定义和扩展这些设置项。
