uniform method

Stream<num> uniform(num a, num b, { int? maxCount, })

returns uniformly distributed integer random number from [a,b) range The methods transform the state using the MWC algorithm and return the next uniformly-distributed random number of the specified type, deduced from the input parameter type, from the range [a, b) . https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#a8325cc562269b47bcac2343639b6fafc

Implementation

Stream<num> uniform(num a, num b, {int? maxCount}) async* {
  int count = 0;

  if (a is int && b is int) {
    final p = calloc<ffi.Int>();
    try {
      while (true) {
        cvRun(() => cffi.RNG_Uniform(ref, a, b, p));
        yield p.value;

        count++;
        if (maxCount != null && ++count >= maxCount) break;
      }
    } finally {
      calloc.free(p);
    }
  } else {
    final p = calloc<ffi.Double>();
    try {
      while (true) {
        cvRun(() => cffi.RNG_UniformDouble(ref, a.toDouble(), b.toDouble(), p));
        yield p.value;

        count++;
        if (maxCount != null && ++count >= maxCount) break;
      }
    } finally {
      calloc.free(p);
    }
