Flutter Toast Pro

Lightweight, overlay-based toast / loading / progress utilities driven by OverlayPortal and a global FlutterToastProWrapper.

依托 OverlayPortal 与全局 FlutterToastProWrapper 的轻量吐司、加载与进度组件。

❗ 注意：message,loading,progress 三类 Overlay 互斥显示，调用任意一类时会自动关闭其他两类。

❗ Note: message, loading, and progress overlays are mutually exclusive; invoking one type will automatically dismiss the others.

📦 Installation 安装

Add the dependency manually or run flutter pub add:

在 pubspec.yaml 中添加依赖，或执行下方命令：

dependencies:
  flutter_toast_pro: ^latest

  flutter pub add flutter_toast_pro

🚀 Quick Start 快速开始

Wrap your root widget (e.g., MaterialApp) with FlutterToastProWrapper.

使用 FlutterToastProWrapper 包裹根 Widget（如 MaterialApp）。
Invoke static helpers such as FlutterToast.showSuccessMessage wherever needed.

在任意位置调用 FlutterToast 静态方法即可。

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return FlutterToastProWrapper(
      autoClose: true,
      closeDuration: const Duration(seconds: 3),
      child: MaterialApp(
        title: 'Flutter Toast Demo',
        home: const HomePage(),
      ),
    );
  }
}

class HomePage extends StatelessWidget {
  const HomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: FilledButton(
          onPressed: () => FlutterToast.showSuccessMessage('保存成功'),
          child: const Text('显示 Toast'),
        ),
      ),
    );
  }
}

🔔 Message API 消息接口

Method / 方法	Default Type / 默认类型	Key Params / 主要参数	Notes / 说明
`FlutterToast.showMessage`	`MessageType.info`	`message`, `closeDuration`, `type`, `alignment`, `extra`	Basic toast with configurable semantics and timer. 基础文本吐司，可自定义语义与倒计时。
`showSuccessMessage` / `showWarningMessage` / `showErrorMessage`	Semantic presets / 语义预设	Same as above / 同上	Sugar helpers that map to success, warning, and error styles. 语法糖，对应成功、警告、错误配色。
`hideMessage()`	–	–	Manually dismiss the current toast and cancel timers. 手动关闭当前消息并终止定时器。

Alignment defaults to Alignment.topCenter; extra carries arbitrary payloads for custom builders.

默认对齐为 Alignment.topCenter，extra 可传入任意扩展数据供自定义 Builder 使用。

Auto Close 自动关闭

FlutterToastProWrapper.autoClose: enable or disable auto dismissal for message toasts (default: true). 控制是否对消息吐司启用自动关闭（默认启用，仅对 ToastType.message 生效）。
FlutterToastProWrapper.closeDuration: global fallback duration, overridable per call. 全局默认倒计时，可在 showMessage 时单独指定。

⏳ Loading & Progress 加载与进度

Method / 方法	Purpose / 用途
`FlutterToast.showLoading({String? message, AlignmentGeometry alignment, Map<String, dynamic> extra})`	Show a modal loading overlay with optional text. 展示可选文案的加载遮罩。
`FlutterToast.hideLoading()`	Hide the active loading overlay. 隐藏当前加载层。
`FlutterToast.showProgress(double progress, {String? message, AlignmentGeometry alignment, Map<String, dynamic> extra})`	Display determinate progress (0.0–1.0). 展示 0.0~1.0 的确定性进度。
`FlutterToast.hideProgress()`	Dismiss the progress overlay. 关闭进度弹层。

Default widgets appear centered with a modal barrier; feel free to swap in custom builders just like messages.

默认 UI 为屏幕中心的模态遮罩，可像消息一样完全替换为自定义组件。

🎨 Custom UI 自定义界面

FlutterToastProWrapper exposes three builders. Supply your own widgets to align, animate, or theme the overlays.

三个 Builder 可用于完全定制 UI，以下示例演示如何替换默认消息组件：

FlutterToastProWrapper(
  messageBuilder: (
    BuildContext context,
    String message,
    MessageType type,
    AlignmentGeometry alignment,
    Map<String, dynamic> extra,
  ) {
    return Align(
      alignment: alignment,
      child: DecoratedBox(
        decoration: BoxDecoration(
          color: Colors.black.withOpacity(0.7),
          borderRadius: BorderRadius.circular(12),
        ),
        child: Padding(
          padding: const EdgeInsets.symmetric(horizontal: 24, vertical: 16),
          child: Text(message, style: const TextStyle(color: Colors.white)),
        ),
      ),
    );
  },
  loadingBuilder: (context, message, alignment, extra) => CustomLoading(message: message),
  progressBuilder: (context, progress, message, alignment, extra) => CustomProgress(value: progress),
  child: MaterialApp(...),
);

The wrapper covers the full screen; align widgets according to the provided alignment.

Wrapper 铺满全屏，根据传入的 alignment 自行定位。
Use extra can be extended data such as custom data, IDs, etc. at the business layer.

extra 可在业务层传入自定义的数据、 ID 等扩展数据。
