Unlike traditional connectivity packages that only report whether a device is connected to WiFi, mobile data, or Ethernet, internet_quality_codespark evaluates actual internet responsiveness and classifies network quality into meaningful categories such as Excellent, Good, Poor, Very Poor, and Offline.

Built with pure Dart and Flutter. No external dependencies.

---

Why internet_quality_codespark?

Most connectivity solutions answer:

WiFi
Mobile
Ethernet
Offline

However, applications often need answers to more important questions:

• Is the internet fast enough for a video call?
• Should I upload a large file right now?
• Is the network quality degrading?
• Can I safely fetch high-resolution content?
• Is the device connected but unable to reach the internet?

This package focuses on internet quality rather than simple connectivity status.

Internet Quality Levels

enum InternetQualityLevel {
  excellent,
  good,
  poor,
  veryPoor,
  offline,
}

Example classifications:

Latency	Quality
0-150ms	Excellent
151-400ms	Good
401-800ms	Poor
801ms+	Very Poor
Failure	Offline

---

Quick Start

---

Check Internet Quality Level

Check Internet Availability

final hasInternet =
    await InternetQuality.hasInternet();

Returns:

true
false

---

Check Internet Quality

// ...existing code...

---

Get Detailed Internet Quality Metrics

final quality =
    await InternetQuality.check();

Example:

if (quality ==
    InternetQualityLevel.poor) {
  // Reduce image quality
}

---

Get Detailed Results

// ...existing code...

---

Get Current Average Latency

final result =
    await InternetQuality.checkDetailed();

Example:

print(result.quality);
print(result.averageLatencyMs);

---

Detailed Result Model

class InternetQualityResult {
  final InternetQualityLevel quality;

  final int dnsLatencyMs;

  final int socketLatencyMs;

  final int httpLatencyMs;

  final int averageLatencyMs;

  final DateTime timestamp;
}

Example:

final result =
    await InternetQuality.checkDetailed();

print(result.dnsLatencyMs);
print(result.socketLatencyMs);
print(result.httpLatencyMs);
print(result.averageLatencyMs);

---

Monitor Internet Quality

// ...existing code...

---

Monitor Internet Quality Changes

Listen continuously for quality changes:

InternetQuality.monitor(
  interval: Duration(seconds: 5),
).listen(
  (result) {
    print(result.quality);
  },
);

---

Get Current Latency

final latency =
    await InternetQuality.getLatency();

print(latency);

Returns:

120

Latency is returned in milliseconds.

---

Example Use Cases

Adaptive Image Loading

final quality =
    await InternetQuality.check();

if (quality ==
    InternetQualityLevel.excellent) {
  loadHighResolutionImages();
} else {
  loadCompressedImages();
}

---

Video Upload Protection

final quality =
    await InternetQuality.check();

if (quality ==
    InternetQualityLevel.poor ||
    quality ==
    InternetQualityLevel.veryPoor) {
  showRetryMessage();
}

---

Network Diagnostics

final result =
    await InternetQuality.checkDetailed();

debugPrint(
  'Latency: ${result.averageLatencyMs}ms',
);

---

How It Works

The package evaluates internet quality using multiple network checks:

DNS Lookup

Measures DNS response latency.

InternetAddress.lookup(...)

Socket Connection

Measures raw connection latency.

Socket.connect(...)

HTTP Request

Measures actual internet responsiveness.

HttpClient(...)

The collected metrics are combined and classified into an internet quality level.
