wifi_indicator 1.0.3

A WiFi indicator widget that supports real-time network monitoring, multiple signal states, and filled/outline styles

WiFi Indicator

A small, customizable Flutter package that draws a WiFi indicator using Canvas and monitors platform connectivity using connectivity_plus + provider under the hood.

This package provides a compact WiFi icon widget that can be used as a live network indicator or as a static icon on all platforms (mobile, web, desktop).

Features

• Real-time network monitoring using connectivity_plus.
• Lightweight state management with provider (exposed as WifiIndicatorProvider).
• Canvas-drawn WiFi icons: Filled and Outline variants.
• Signal-strength aware icons (No connection / 2G / 3G / 4G / 5G mapped to 0..4 bars).
• Built-in recovery animation: when connection is regained, a short step animation builds bars like macOS, then settles to the real status.
• Fully configurable color per-status via statusColors.

Installation

Add the package to your pubspec.yaml (this package already depends on connectivity_plus and provider):

dependencies:
  flutter:
    sdk: flutter
  wifi_indicator: ^1.0.3

If you are using the example in this repo, run:

cd example
flutter pub get
flutter run -d chrome

Quick Usage

Wrap your app (or a subtree) with WifiIndicatorProvider so the package can monitor connectivity changes. Place WifiIndicator where you want the icon to appear.

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

void main() => runApp(
  WifiIndicatorProvider(
    child: MaterialApp(home: Scaffold(body: Center(child: Home()))),
  ),
);

class Home extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        // Live indicator that follows device connectivity
        WifiIndicator(size: 36, type: WifiIndicatorType.filled),

        const SizedBox(width: 24),

        // Static indicator for documentation / UI (overrideStatus)
        WifiIndicator(
          size: 36,
          type: WifiIndicatorType.outline,
          overrideStatus: NetworkStatus.fast, // force 4G/3 bars look
        ),
      ],
    );
  }
}

Notes:

• WifiIndicator automatically listens to network updates from WifiIndicatorProvider (which instantiates the internal NetworkProvider).
• To show a static state (for design or testing), provide overrideStatus.

Multi-color guide (per-status colors)

You can pass a map of NetworkStatus to Color to the WifiIndicator so each status uses a color you choose:

final statusColors = {
  NetworkStatus.none: Colors.red,
  NetworkStatus.slow: Colors.orange,
  NetworkStatus.medium: Colors.yellow.shade700,
  NetworkStatus.fast: Colors.lightGreen,
  NetworkStatus.veryFast: Colors.green,
};

WifiIndicator( 
  size: 40,
  type: WifiIndicatorType.filled,
  statusColors: statusColors,
  overrideStatus: NetworkStatus.veryFast,
);

This is convenient for dashboards where you want color to reflect severity or quality.

API summary

• WifiIndicatorProvider — wrap your app and enables connectivity monitoring.
• WifiIndicator — the widget. Constructor highlights:
  • size (double) — width/height in logical pixels.
  • type (WifiIndicatorType.filled | WifiIndicatorType.outline).
  • color (Color) — default color when statusColors not provided.
