nextBool method

@override bool nextBool()

Generates a random boolean value.

Example:

var boolValue = Random().nextBool(); // true or false, with equal chance.

Implementation

@override
bool nextBool() {
  // we're returning bits from higher to lower: like uint32s from int64s
  if (boolCache_prevShift == 0) {
    boolCache = nextRaw32();
    boolCache_prevShift = 31;
    return boolCache & 0x80000000 != 0;
  } else {
    assert(boolCache_prevShift > 0);
    boolCache_prevShift--;
    final result = (boolCache & (1 << boolCache_prevShift)) != 0;
    return result;
  }
}
