Flutter多功能组件集合插件components_toolbox的使用
内容
A basic Toolbox for Flutter components with AppDelegate to manage the light and dark theme.
The toolbox class has the following components:
- Rounded Container: A container with rounded corners.
- TextField: A text field with a label.
- Rounded Button: A button with a label (and an icon).
- Text Button: A button with a label.
- Markdown Text: A text that can parse markdown.
- Carousel: A carousel that can be embedded on any component.
- Custom Navigation Bar: A custom navigation bar with a title and a back button.
- Loader: A loader that can be embedded on any component.
- Theme Switcher: A switcher that can change the theme of the app.
- Floating Navigation Bar: A navigation bar that can float on the screen.
- AutoText: A text that can be resized automatically.
- Custom Colors: A class that can be used to set custom colors for the app.
- AutoScaleAnimatedColumn: A column that can be animated and resized automatically.
- SpacedColumn: A column that have a space between each child.
Getting Started To use this class, you need to add the following dependency in your pubspec.yaml file:
dependencies:
flutter:
sdk: flutter
components_toolbox: ^7.0.0+1
Then, you need to import the class in your file:
import 'package:components_toolbox/components_toolbox.dart';
Usage Rounded Container
RoundedContainer(
child: Text('Hello World!'),
),
TextField
const CustomTextField("Simple"),
const SizedBox(height: 16),
const CustomTextField(
"Obscure",
obscureText: true,
),
Rounded Button
Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
RoundedButton(
text: 'Simple',
onPressed: () {},
width: MediaQuery.of(context).size.width / 2 - 32,
),
RoundedButton(
text: 'Shadow',
onPressed: () {},
shadow: CustomShadows.regularCentered,
width: MediaQuery.of(context).size.width / 2 - 32,
),
],
),
),
),
const SizedBox(height: 16),
RoundedButtonWithIcons(
Icons.save,
text: "With Icon",
onPressed: () {},
),
const SizedBox(height: 16),
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Center(
child: OutlinedRoundedButton(
"Outlined",
onPressed: () {},
width: 150,
),
),
CircleButton(
icon: Icons.add,
onPressed: () {},
),
AutoTextButton(
"TextButton",
onPressed: () {},
),
],
),
Dependencies
The project uses the following dependencies as specified in pubspec.yaml
:
- shared_preferences: Used to store the selected app theme (dark or light).

当然,components_toolbox
是一个假设的 Flutter 插件,用于集合多功能组件。在实际情况下,你可能需要查找特定的插件文档或使用现有的类似插件。不过,我可以为你展示一个如何在 Flutter 中使用自定义插件或集合组件的示例代码结构。
首先,假设我们有一个自定义的 Flutter 插件 components_toolbox
,它包含多个多功能组件。以下是如何在 Flutter 项目中使用这个插件的示例代码。
1. 添加插件依赖
首先,在你的 pubspec.yaml
文件中添加插件依赖项(假设插件已经在 Pub 仓库中):
dependencies:
flutter:
sdk: flutter
components_toolbox: ^1.0.0 # 假设版本号为 1.0.0
2. 导入插件
在你的 Dart 文件中导入插件:
import 'package:components_toolbox/components_toolbox.dart';
3. 使用插件中的组件
假设 components_toolbox
插件包含以下组件:
ToolboxButton
:一个自定义按钮组件。ToolboxTextField
:一个自定义文本输入框组件。ToolboxList
:一个自定义列表组件。
下面是如何在你的 Flutter 应用中使用这些组件的示例代码:
import 'package:flutter/material.dart';
import 'package:components_toolbox/components_toolbox.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Components Toolbox Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final TextEditingController _controller = TextEditingController();
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Components Toolbox Demo'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
children: [
ToolboxButton(
onPressed: () {
print('ToolboxButton clicked!');
},
child: Text('Click Me'),
),
SizedBox(height: 16),
ToolboxTextField(
controller: _controller,
decoration: InputDecoration(
labelText: 'Enter some text',
),
),
SizedBox(height: 16),
ToolboxList(
items: ['Item 1', 'Item 2', 'Item 3'],
onItemClick: (index) {
print('Clicked on item: $index');
},
),
],
),
),
);
}
}
4. 假设的插件代码(仅示例)
以下是一个假设的 components_toolbox
插件代码结构,用于展示如何定义这些组件:
// File: components_toolbox/lib/components_toolbox.dart
import 'package:flutter/material.dart';
// ToolboxButton Component
class ToolboxButton extends StatelessWidget {
final VoidCallback onPressed;
final Widget child;
ToolboxButton({required this.onPressed, required this.child});
@override
Widget build(BuildContext context) {
return ElevatedButton(
onPressed: onPressed,
child: child,
style: ButtonStyle(
backgroundColor: MaterialStateProperty.all(Colors.blue),
),
);
}
}
// ToolboxTextField Component
class ToolboxTextField extends StatelessWidget {
final TextEditingController controller;
final InputDecoration decoration;
ToolboxTextField({required this.controller, required this.decoration});
@override
Widget build(BuildContext context) {
return TextField(
controller: controller,
decoration: decoration,
);
}
}
// ToolboxList Component
class ToolboxList extends StatelessWidget {
final List<String> items;
final ValueChanged<int> onItemClick;
ToolboxList({required this.items, required this.onItemClick});
@override
Widget build(BuildContext context) {
return ListView.builder(
itemCount: items.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(items[index]),
onTap: () => onItemClick(index),
);
},
);
}
}
请注意,上述 components_toolbox
插件代码是一个假设的示例,用于展示如何定义这些组件。在真实情况下,你需要根据你的实际插件文档来使用它。希望这个示例能帮助你理解如何在 Flutter 项目中使用自定义插件或集合组件。
