        */
        systemNavigationBarColor: Colors.transparent,
        systemNavigationBarIconBrightness: Brightness.dark,
      ),
      child: GetMaterialApp(
        title: 'Flutter3 Trip',
        debugShowCheckedModeBanner: false,
        theme: ThemeData(
          colorScheme: ColorScheme.fromSeed(seedColor: Color(0xffffaa00)),
          useMaterial3: true,
          // 修复windows下字体不一致情况
          fontFamily: Platform.isWindows ? 'Microsoft YaHei' : null
        ),
        home: const Layout(),

        // 初始化弹窗key
        navigatorKey: MyDialog.navigatorKey,

注意：如果开发中遇到升级flutter3.32版本以上，出现手机底部导航栏背景黑色，可以试试如下修复方法。

AnnotatedRegion(

    systemNavigationBarIconBrightness: Brightness.dark,

flutter3自定义滚动槽

late ScrollController indicatorController = ScrollController();

// 记录滚动位置
final ValueNotifier<double> indicatorOffset = ValueNotifier(0);

@override

  indicatorController.addListener(() {
    indicatorOffset.value = indicatorController.position.pixels / indicatorController.position.maxScrollExtent;

Column(

        controller: indicatorController,
        scrollDirection: Axis.horizontal,
        padding: EdgeInsets.symmetric(horizontal: 12.0),
        child: Row(
          ...
        ),
      ),
    ),
    // 指示槽
    ValueListenableBuilder(
      valueListenable: indicatorOffset,
      builder: (context, offset, child) {
        final indicatorWidth = 20.0;
        final trackWidth = 50.0;
        // 可移动的最大距离
        final maxTranslate = trackWidth - indicatorWidth;
        // 根据滚动进度计算位移
        final translateX = maxTranslate * offset.clamp(0.0, 1.0);
        return Stack(
          children: [
            // 轨道
            Container(
              decoration: BoxDecoration(

        );
      },
    ),
  ],
),

flutter3酒店预订模块

预订模块单独封装成了一个组件。

• 热门城市、位置品牌选择

使用 scrollable_positioned_list 组件实现滑动字母索引滚动到指定列表位置。

ItemScrollController itemScrollController = ItemScrollController();

ScrollablePositionedList.builder(
  itemScrollController: itemScrollController,
  itemCount: citylist.length,
  itemBuilder: (context, index) {
    // ...
  }
)

// 侧边索引
Align(
  alignment: Alignment.centerRight,
  child: GestureDetector(
    child: Container(
      color: Colors.transparent,
      width: 25.0,
      child: Column(
        mainAxisSize: MainAxisSize.min,
        mainAxisAlignment: MainAxisAlignment.center,
        children: List.generate(pinyinList.length, (index) {
          return GestureDetector(
            child: Container(
              ...
            ),
            onTapDown: (details) {
              // 跳转指定索引位置
              itemScrollController.jumpTo(index: index);
              setState(() {
                selectedLetter = pinyinList[index];
                showBubble = true;
              });
              Future.delayed(Duration(milliseconds: 200), () {
                setState(() {
                  selectedLetter = '';
                  showBubble = false;
                });
              });
            },
          );
        }),
      ),
    ),
    onVerticalDragUpdate: (details) {
      updateSelectedLetter(details.localPosition);
    },
    onVerticalDragEnd: (details) {
      setState(() {
        selectedLetter = '';
        showBubble = false;
      });
    },
  ),
),

• 入住/离店日期选择

使用 syncfusion_flutter_datepicker 插件选择入住/离店日期。

// 入住日期
DateTime startDate = DateTime.now();
// 离店日期
DateTime endDate = DateTime.now().add(Duration(days: 1));

GestureDetector(
  child: Container(
    padding: EdgeInsets.all(10.0),
    decoration: BoxDecoration(
      border: Border(bottom: BorderSide(color: Color(0xfff5f5f5))),
    ),
    child: Row(
      spacing: 10.0,
      children: [
        Icon(Icons.calendar_month_outlined),
        Expanded(
          child: Row(

                ],
              ),
              Container(

                // DateTime 类提供了 difference 方法，可以计算两个日期之间的时间差，返回一个 Duration 对象。通过 Duration 的 inDays 属性，可以获取天数差。
                child: Text('共${endDate.difference(startDate).inDays}晚'),
              ),
              Column(

flutter3自定义酒店筛选列表

使用 SizeTransition 和 FadeTransition 组件实现下拉动画效果。
