⚡ AnywhereLoader – Effortless Overlay Loader Without Context or Dependencies

A lightweight and customizable overlay loader for Flutter. No Stack, no context, no complex state management—just one-line integration to show loaders globally.

Features

• 🟢 Uses Overlay instead of Stack for smooth integration.
• 🎨 Customizable font size, font color, and font family.
• 🔄 Supports async operations.
• 🔍 Blur effect on background while loading.
• 🚀 Simple API: Just wrap your widget and call startLoader().

Installation

Add this to your pubspec.yaml:

dependencies:
anywhere_loader: latest_version

Then run:

flutter pub get

Usage

1️⃣ ⚙️ Setup

Wrap your screen (not the whole app) inside AnyWhereLoaderContextProvider. This should be placed inside the MaterialApp:

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

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Anywhere Loader Demo',
      debugShowCheckedModeBanner: false,
      home: AnyWhereLoaderContextProvider(
        child: HomePage(),
      ),
    );
  }
}

2️⃣ Start and Stop Loader

To start the loader anywhere in your app:

AnywhereLoader.instance.startLoader(
  text: "Loading data...",
  seconds: 5, // Default is 10 seconds
  fontSize: 18,
  fontColor: Colors.white,
  fontFamily: 'Arial',
);

To stop the loader manually:

AnywhereLoader.instance.stopLoader();

3️⃣ Using showAsyncLoader() (Recommended for async calls)

Use this method to automatically show a loader while executing any async function like API calls, database operations, etc.

await AnyWhereLoader.instance.showAsyncLoader(
 asyncFunction: () async {
 // Simulate a network call or long task
 await Future.delayed(const Duration(seconds: 5));
},
 text: "Loading, please wait...",
);

✅ The loader automatically starts and stops. 💡 Ideal for API calls or tasks where you don’t want to manually call startLoader() and stopLoader().

4️⃣ Use Custom Loader Widget

You can replace the default loader with your own widget:

AnywhereLoader.instance.startLoader(
  customWidget: Center(
    child: Column(
      mainAxisSize: MainAxisSize.min,
      children: [
        CircularProgressIndicator(),
        SizedBox(height: 10),
        Text("Fetching data...")
      ],
    ),
  ),
);

5️⃣ 🍎 Customization for iOS (Cupertino Loader)

You can enable a native iOS-style progress indicator using the isIos: true flag. You can also customize its radius.

ElevatedButton(
  onPressed: () {
    AnyWhereLoader.instance.startLoader(
      blurSigma: 5,
        backgroundColor: Colors.black,
        opacity: 0.5,
        isIos: true,              // 👈 Enables CupertinoActivityIndicator
        iosProgressRadius: 20,    // 👈 Customize the radius of the Cupertino spinner
        progressColor: Colors.blue, // 👈 Optional color for the Cupertino spinner
        );

        Future.delayed(const Duration(seconds: 3), () {
          AnyWhereLoader.instance.stopLoader();
        });
    },
    child: const Text("Show Loader"),
    );

✅ CupertinoActivityIndicator gives a native iOS feel 🎛️ Use isIos: false (default) to switch back to Material spinner 🎯 Great for iOS-specific UI consistency
