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.
