Learn Dart: The First Step to Flutter

Solution: Smart Grid Energy Distributor

Understand how to apply Dart operators including truncating division, modulo, and logical AND within a practical context. This lesson guides you through using these operators to calculate fully charged batteries, remainder kilowatts, and logical conditions in an energy distribution scenario, helping you write clear and effective code.

We'll cover the following...
Dart
void main() {
  int totalKilowatts = 1250;
  int batteryCapacity = 100;
  int reserveThreshold = 10;
  int fullBatteries = totalKilowatts ~/ batteryCapacity;
  int remainingKilowatts = totalKilowatts % batteryCapacity;
  bool isStableSurplus = remainingKilowatts == 0 && fullBatteries > reserveThreshold;
  print("Full batteries: $fullBatteries");
  print("Remaining kilowatts: $remainingKilowatts");
  print("Stable surplus active: $isStableSurplus");
}
