Flutter UI组件插件cotton_candy_ui的使用

Cotton Candy UI 是一个用于美化您的应用界面的UI包。此UI包基于 Shiban 的设计系统。

开始使用

添加依赖

在你的项目中添加 cotton_candy_ui 包。打开终端并运行以下命令：

$ flutter pub add cotton_candy_ui

这将会在你的 pubspec.yaml 文件中添加一行类似如下的依赖项：

dependencies:
  cotton_candy_ui: ^0.2.0

或者，你可以直接编辑 pubspec.yaml 文件来添加该依赖项。

导入库

在 Dart 代码中导入 cotton_candy_ui 库：

import 'package:cotton_candy_ui/cotton_candy_ui.dart';

示例代码

以下是一个完整的示例代码，展示了如何使用 cotton_candy_ui 中的一些组件：

import 'package:flutter/material.dart';
import 'package:cotton_candy_ui/cotton_candy_ui.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  [@override](/user/override)
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  final String title = "Cotton Candy UI Example";
  late FixedExtentScrollController hourScrollController;
  late FixedExtentScrollController minuteScrollController;
  late FixedExtentScrollController ampmScrollController;

  [@override](/user/override)
  void initState() {
    // 初始化时钟控制器
    hourScrollController = FixedExtentScrollController(
        initialItem: (TimeOfDay.now().hour > 11)
            ? TimeOfDay.now().hour - 12
            : TimeOfDay.now().hour);
    minuteScrollController =
        FixedExtentScrollController(initialItem: TimeOfDay.now().minute);
    ampmScrollController = FixedExtentScrollController(
        initialItem: (TimeOfDay.now().hour > 11) ? 1 : 0);
    super.initState();
  }
