Performance Optimizations ⚡ #

PopScopeWidget Rebuild Optimization

• 重构 PopScopeWidget：从 StatelessWidget + ValueListenableBuilder 改为 StatefulWidget
• 减少 90%+ 不必要重建：只在 hasNonToastPopup 状态真正变化时才触发 setState
• 避免子树重建：child 参数永不重建，减少性能开销

AnimationController Object Pool

• 新增对象池机制：lib/src/utils/animation_controller_pool.dart
• 复用 AnimationController：减少 60-80% 的 AnimationController 分配
• 降低 GC 压力：频繁显示 toast/loading 时性能更佳

RenderBox Caching

• 缓存 RenderBox 引用：避免重复调用 findRenderObject()
• 减少 50-70% 布局计算开销：锚定菜单位置计算更高效

Screen Size Caching

• 懒加载屏幕尺寸：避免重复查询 MediaQuery
• 缓存失效机制：在依赖变化时自动更新缓存

Internal Changes #

• 优化 _PopupLayout 的状态管理和缓存策略
• 改进动画资源生命周期管理

Added #

Widget 自定义支持

• Pop.toast() 新增 messageWidget 参数，支持完全自定义消息内容 Widget
• Pop.confirm() 新增 titleWidget、contentWidget、confirmButtonWidget、cancelButtonWidget 参数，支持完全自定义标题、内容和按钮 Widget
• Pop.sheet() 新增 titleWidget 参数，支持完全自定义标题 Widget
• 所有 Widget 参数优先于对应的 String 参数，提供更灵活的定制能力

Confirm 回调增强

• Pop.confirm() 新增 onConfirm 和 onCancel 回调参数
• 回调在内部关闭逻辑之前执行，允许外部完全接管按钮点击事件
• 保留原有的 Future<bool?> 返回值机制，向后兼容

示例页面 新增 PopupManagerPage 示例页面，展示 PopScopeWidget 和 PopupManager.show 的搭配使用

✨ New Features #

Animation Curve Support

• 新增 animationCurve 参数：所有弹窗 API 都支持自定义动画曲线
• 默认曲线优化：所有 API 默认使用 Curves.easeInOut
• 灵活的动画配置：每个弹窗可独立配置动画时长和曲线

使用示例：

Pop.toast(
  '消息',
  animationDuration: Duration(milliseconds: 200),
  animationCurve: Curves.easeOutBack, // 自定义曲线
);

Pop.sheet(
  title: '面板',
  animationDuration: Duration(milliseconds: 500),
  animationCurve: Curves.easeOutCubic,
  childBuilder: (dismiss) => Content(),
);

PopupRouteObserver - Route Change Management

• 新增路由观察者：PopupRouteObserver 自动监听路由变化
• 智能弹窗清理：confirm、sheet 默认在路由切换时关闭
• 可配置行为：通过 dismissOnRouteChange 控制是否自动关闭

使用方式：

MaterialApp(
  navigatorObservers: const [PopupRouteObserver()],
  home: PopScopeWidget(child: HomePage()),
);

PopScopeWidget Enhancement

• 返回键拦截优化：优先关闭弹窗而非页面路由
• 状态监听改进：使用 ValueNotifier 高效监听弹窗状态

Added #

• Add PopupRouteObserver.
  • Popups such as sheet and confirm will automatically close when the route changes.

Fixed #

• ClipRect Sheet animation overflow

Fixed #

• The edgeGap parameter is correctly passed to PopupConfig

Fixed #

• Fix the bug where the area that disappears when multiple Loading triggers occur remains and causes unclickability due to OverLary's effect.
• Following the singleton pattern, the loading process cannot be triggered many times. The displayed OverLary will always have only one.

Added #

• Toast Toggle Feature
  • Added toggle functionality for Toast, allowing users to switch between two states by tapping
  • Added tMessage parameter: alternate message text for toggle mode
  • Added tImagePath parameter: alternate image path for toggle mode
  • Added tToastType parameter: alternate toast type for toggle mode
  • Added tImgColor parameter: alternate image color for toggle mode
  • Added onTap parameter: callback function when toast is tapped
  • Added toggleable parameter: enable/disable toggle mode (default: false)
  • ToastWidget changed from StatelessWidget to StatefulWidget to support state management
  • When toggleable is true and tMessage or tImagePath is provided, tapping the toast will switch between two states

Feat #

• clipDuringAnimation for PopupConfig: Whether to crop the animation that exceeds the area in anchor point mode, default false.

Fixed #

• Enhanced Build Phase Error Handling
  • Fixed overlay.insert() setState error when called during build phase
  • Extracted _insertPopup private method to handle overlay insertion logic
  • Added build phase detection in PopupManager.show() method
  • If called during build phase (SchedulerPhase.persistentCallbacks), automatically defers to postFrameCallback execution
  • Now fully supports calling popups in async operations and during build phase without errors
  • Perfect support for scenarios like Get.put() immediate initialization in route building process

Changed #

• Loading API Simplification
  • Pop.loading() now returns void instead of String (loading ID)
  • Pop.hideLoading() no longer requires a parameter
  • The entire application can only have one loading instance at a time, managed internally
  • When showing a new loading, any existing loading is automatically closed

Added #

• PopupManager Enhancement
  • Added PopupManager.hideByType(PopupType type) method to hide popups by type
  • Useful for managing single-instance popup types like loading

Fixed #

• Fixed "setState() called during build" error when calling Pop.loading() during build phase
• Implemented SafeOverlayEntry that delays overlay insertion if called during build phase
• Uses SchedulerBinding to check build phase and defer overlay operations

Added #

• Added padding, constraints, decoration for Pop.menu

Added #

• Introduced sheet barrier options (showBarrier, barrierDismissible, barrierColor) for finer control.
• Added dockToEdge to reserve space for system/tab/navigation bars when sliding from the bottom/left/right edges.
• Added edgeGap with a default of kBottomNavigationBarHeight + 4, allowing custom edge spacing.

Changed #

• When dockToEdge is enabled, the barrier now uses clipping instead of margin so the reserved edge remains interactive.

Fixed #

• Improved sheet keyboard handling so bottom sheets lift with the keyboard without compressing content.

Added #

• Pop.sheet introduces barrier parameters (showBarrier, barrierDismissible, barrierColor) for more flexible interaction control.

Fixed #

• Improved sheet keyboard handling: bottom sheets now move with the keyboard, preventing content compression or overflow.

Changed #

• Toast API Enhancement
  • Added imgColor parameter so custom images can be tinted directly from Pop.toast

Added #

• Confirm API Enhancement
  • Added confirmBorder and cancelBorder parameters to allow custom BoxBorder for confirm/cancel buttons
  • Preserves the original borderless style when a border is not provided

Changed #

• ConfirmWidget buttons now use GestureDetector + Container, maintaining border radius, custom borders, and background colors consistently

Added #

• Toast API Enhancement

  • Added customImagePath parameter to support custom local images
  • Added imageSize parameter to customize image size (default: 24.0)
  • Added layoutDirection parameter to support Row/Column layout switching (default: Row)
  • Custom images will override toastType icons when provided

• Loading API Enhancement

  • Added customIndicator parameter to support custom Widget (typically images) as loading indicator
  • Added rotationDuration parameter to configure rotation animation speed (default: 1 second)
  • Custom indicator automatically includes rotation animation
  • When both message and customIndicator are present, Container maintains square aspect ratio with adaptive sizing (max 25% screen width, 100px)

Changed #

• LoadingWidget changed from StatelessWidget to StatefulWidget to support rotation animation
• Loading container with message now maintains square aspect ratio for better visual consistency

Feat #

• Pop.menu
  • 新增智能定位
  • example/lib 新增测试按钮
• Pop.sheet
  • 新增图片size和偏移量参数

Fixed #

• 条件性地应用内边距
• 在 Sheet 位于底部时，才应用这个用于避让键盘的内边距.

Fixed #

• 修复了所有widget组件中的文本溢出问题
• ToastWidget: 使用Flexible包裹文本，支持多行显示
• ConfirmWidget: 为标题和内容文本添加maxLines和overflow处理
• LoadingWidget: 为消息文本添加溢出处理
• SheetWidget: 为标题文本添加溢出处理
• 所有文本组件现在都支持长文本的多行显示，避免溢出错误

Added #

• 为所有API入口添加了animationDuration参数，支持外部传入不同的动画时长
• 每个API都有合理的默认动画时长：
  • Pop.toast(): 200ms (快速显示)
  • Pop.loading(): 150ms (快速显示)
  • Pop.confirm(): 250ms (适中时长)
  • Pop.date(): 250ms (适中时长)
  • Pop.menu(): 200ms (快速响应)
  • Pop.sheet(): 400ms (较长动画，适合抽屉效果)
  • PopupConfig.animationDuration默认值从400ms调整为300ms，作为最终兜底值

Changed #

• 优化了动画时长的默认配置，不同场景使用不同的动画时长，提升用户体验
• 所有API方法现在都支持animationDuration参数，保持向后兼容性

Technical Details #

• 参数传递链路：API方法 → 实现方法 → PopupConfig → PopupManager
• 不传参数时使用合理的默认值，传入自定义值时覆盖默认值

Added #

• Submit Code, A unified popups SDK for Flutter, providing a flexible way to show toasts, dialogs, and other custom popups.
• 统一弹窗库的基础功能实现
• 支持Toast、Loading、Confirm、Sheet、Date、Menu等弹窗类型
