charId static method
Returns UnitId.cycleId of given index
.
UnitId.az is used as input - so result is not case sensitive and without numbers.
Set digitOffset
to specify minimum length of final result.
For UnitId.aZ sequence results are: 0 - a 1 - b 26 - aa 27 - ab
Implementation
static String charId(int index, {int digitOffset = 0}) =>
cycleId(index + _digitCycleOffset(digitOffset, az.length), az);
