getDouble method

@override double getDouble(String key, { double defaultValue = 0.0, })

Retrieves a double value from an environment variable.

If the value cannot be parsed as a double, returns defaultValue.

final rate = env.getDouble('EXCHANGE_RATE', defaultValue: 1.0);
final threshold = env.getDouble('THRESHOLD'); // defaults to 0.0

Implementation

@override
double getDouble(String key, {double defaultValue = 0.0}) {
  final value = _env[key];
  if (value == null) return defaultValue;
  return double.tryParse(value) ?? defaultValue;
}
