removeStartZero method

String removeStartZero(String barcode)

Removes leading zeros from the barcode.

This method removes all consecutive zeros at the beginning of the barcode. If the barcode contains only zeros, an empty string is returned.

Example:

final cleaner = BarcodeCleaner();
final result = cleaner.removeStartZero('00012345'); // Returns '12345'

Implementation

String removeStartZero(String barcode) {
  return barcode.replaceFirst(RegExp(r'^0+'), '');
}
