int compareVersions(String a, String b)

Implementation

int compareVersions(String a, String b) {
  final pa = a.split('.').map(int.parse).toList();
  final pb = b.split('.').map(int.parse).toList();

  final len = pa.length > pb.length ? pa.length : pb.length;

  for (var i = 0; i < len; i++) {
    final va = i < pa.length ? pa[i] : 0;
    final vb = i < pb.length ? pb[i] : 0;
    if (va != vb) {
      return va.compareTo(vb);
    }
  }
  return 0;
