How Blinkit Cracked Android's Performance Puzzle with Droid Dex

🚀 Features

📊 Get performance levels for:

1. CPU
2. Battery
3. Network
4. Storage
5. Memory

⚖️ Weighted performance scoring via custom importance

🔁 Real-time performance updates using event streams

⚡️ Simple API with enums and model wrappers

Usage

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  droid_dex_flutter: ^1.0.1

In your library add the following import:

import 'package:droid_dex_flutter/droid_dex_flutter.dart';

For help getting started with Flutter, view the online documentation.

🧪 Example

Here's a minimal example:

final droidDex = DroidDexFlutter();
await droidDex.init();

final pairs = [
PerformanceClassWeightPair(
performanceClass: PerformanceClass.cpu,
weight: 2.0,
),
PerformanceClassWeightPair(
performanceClass: PerformanceClass.battery,
weight: 1.5,
),
];

final staticLevel = await droidDex.getWeightedPerformanceLevel(pairs);
print("Static Level: ${staticLevel.name}");

// Start real-time stream
final stream = await droidDex.getWeightedPerformanceLevelLiveData(pairs);
stream.listen((level) {
print("Live Level: ${level.name}");
});

For a complete working demo, check the example app.

🎯 API Overview

Initialization

await DroidDexFlutter().init();

Get Performance Level
