Warns when the digit separators create inconsistent groups of digits.

Inconsistent groups are usually a sign of a typo and can significantly reduce readability.

Example​

❌ Bad:

void fn() {
  // LINT: This number has inconsistent number of digits in separated groups.
  //  Try making the groups consistent.
  final value = 1_00_000;

  // LINT: This number has inconsistent number of digits in separated groups.
  //  Try making the groups consistent.
  final value = 11_00_0;

  // LINT: This number has inconsistent number of digits in separated groups.
  //  Try making the groups consistent.
  final another = 1_00_00_000;

  // LINT: This number has inconsistent number of digits in separated groups.
  //  Try making the groups consistent.
  final another = 1_00.000_00_1;
}

✅ Good:

void fn() {
  final value = 10_00_00;
  final dbl = 1_10_00;
}
