Solution: Toxic Gas Leak Detection

Explore how to implement flow control in Dart using nested loops and conditional breaks to detect toxic gas leaks by evaluating sensor readings against a threshold. Understand how to manage loop execution and handle data safely with assertions for reliable detection logic.

We'll cover the following...
Dart
void main() {
  final sensorGrid = [
    [12, 45, 15],
    [50, 105, 120],
    [9, 14, 18],
    [200, 15, 30]
  ];
  
  assert(sensorGrid.isNotEmpty, 'Sensor grid data is missing.');
  for (final sector in sensorGrid) {
    for (final reading in sector) {
      if (reading > 100) {
        print('Evacuate sector! Leak level: $reading');
        break;
      }
    }
  }
}
